Of course, in applying the method means must be adopted for suitably diluting the bacterial mixture.

So that when a " toxin " is spoken of, a mixture with other organic substances is usually implied.

If such were the condition there would always be a certain amount both of free toxin and of free antitoxin in the mixture, and in this case also considerably more than a dose of toxin would have to be added to a " neutral mixture " before the amount of free toxin was increased by a dose, that is, before the mixture became lethal.

If, for example, the brain and spinal cord removed from an animal be bruised and brought into contact with tetanus toxin, a certain amount of the toxicity disappears, as shown by injecting the mixture into another animal.

Of this work, which contains no direct intimation of a fourth figure, and which in general exhibits an astonishing mixture of the Aristotelian and Stoic logic, Prantl speaks with the bitterest contempt.

As in India, after the expulsion of Buddhism, the degrading worship of Siva and his dusky bride had been incorporated into Hinduism from the savage devil worship of Aryan and of non-Aryan tribes, so, as pure Buddhism died away in the north, the Tantra system, a mixture of magic and witchcraft and sorcery, was incorporated into the corrupted Buddhism.

The chief building is the Church of Scotland church, a fine red brick building, a mixture of Norman and Byzantine styles, with lofty turrets and white domes.

His famous description of Greek fire has a most provoking mixture of circumstantial detail with absence of verifying particulars.

A few years after the establishment of the "Abode of Love," a peculiarly gross scandal, in which Prince and one of his female followers were involved, led to the secession of some of his most faithful friends, who were unable any longer to endure what they regarded as the amazing mixture of blasphemy and immorality offered for their acceptance.

These differences took two separate and extreme types, the one of which forcibly separated the two natures so as to deny anything like a real union, while the other insisted upon a mixture of the two, or an absorption of the human in the divine.

When the mixture has been in a tranquil state of fusion for a few minutes it is poured into a mould.

The ore (0 5 gramme) is digested with a mixture of potassium nitrate and nitric acid.

It is then heated with a mixture of ammonium chloride and ammonia, filtered and washed with a hot dilute solution of the same mixture.

In the electrolytic method from o 5 to 5 grammes of ore are treated in a flask or beaker, with a mixture of io cc. of nitric and ro cc. of sulphuric acid, until thoroughly decomposed.

One gramme of the ore is treated in a flask with a mixture of nitric and sulphuric acids and evaporated until all the nitric acid is expelled.

The leading silver minerals are native silver; argentite or silver glance, Ag 2 S, usually containing small amounts of lead, copper and tin; dyscrasite or antimonial silver, Ag 2 Sb to Ag,3Sb, an isomorphous mixture of silver and antimony; proustite or light red silver ore, Ag 3 AsS 3; pyrargyrite or dark red silver ore, Ag 3 SbS 3; stephanite, Ag 5 SbS 4; miargyrite, AgSbS2; stromeyerite, CuAgS; polybasite, 9(Cu 2 S,Ag 2 S) (Sb 2 S 3, As 2 S 3); cerargyrite or horn silver, AgCI; bromite or bromargyrite, AgBr; embolite, Ag(C1,Br); iodite or iodargyrite, AgI.

This may be effected by mixing the dry chloridewith one-fifth of its weight of pure quicklime or one-third of its weight of dry sodium carbonate, and fusing the mixture in a, fire-clay crucible at a bright red heat.

He soon made the crucial discovery - which proved the foundation of the huge industry of artificial alkali manufacture - that the desired end was to be attained by adding a proportion of chalk to the mixture of charcoal and sulphate of soda.

Kdnigs, Ber., 1879, 12, p. 2341) by passing a mixture of acetylene and hydrocyanic acid through a red-hot tube (W.

The whole book is a queer mixture of Hellenism and Hebraism, in which the same method of allegory is applied to Homer and Hesiod as to Moses.

The animal life of Maine shows a mixture of northern and southern forms, and very little that is peculiar as compared with surrounding regions.

The soil is for the most part glacial drift, containing a large mixture of clay with sand or gravel, and the sub-soil is mostly " hard-pan," i.e.

The epics in general show a mixture of Homeric, Ionic and Doric forms. The Bucolics, Mimes, and the " Marriage-song of Helen" (xviii.) are in Doric, with occasional forms from other dialects.

This state of things, due partly to mixture and crossing of races, and partly to independent variation of types, makes the attempt to arrange the whole human species within exactly bounded divisions an apparently hopeless task.

The mixture of the Israelites in Europe by marriage with other nations is probably much greater than is acknowledged by them; yet, on the whole, the race has been preserved with extraordinary strictness, as its physical characteristics sufficiently show.

The living substance, moreover, has its mixture of elaborate and simple compounds associated in a fashion that is peculiar.

Both ideas, or both modes of expressing what is fundamentally the same idea, have this in common, that life is not a sum of the qualities of the chemical elements contained in protoplasm, but a function first of the peculiar architecture of the mixture, and then of the high complexity of the compounds contained in the mixture.

Living matter is a mixture of substances chiefly dissolved in water; the comparison with the crystals has led to a supposed distinction in the mode of growth, crystals growing by the superficial apposition of new particles and living substance by intussusception.

In 1810 Gomez of Lisbon obtained a mixture of alkaloids which he named cinchonino, by treating an alcoholic extract of the bark with water and then adding a solution of caustic potash.

This mixture is known as cinchona febrifuge, and is prepared chiefly from C. succirubra, which succeeds better in India than the other species in cultivation, and grows at a lower elevation, being consequently procurable in large quantities at a comparatively low price.

A mixture of the cinchona alkaloids, consisting principally of cinchonidine sulphate, with smaller quantities of the sulphates of quinine and cinchonine, is sold under the name of "quinetum" at a cheaper rate than quinine.

The fused mass separates into two layers, the upper of which contains a mixture of potassium and lithium sulphates; this is lixiviated with water and converted into the mixed chlorides by adding barium chloride, the solution evaporated and the lithium chloride extracted by a mixture of dry alcohol and ether.

Owing to frequent restorations occasioned by earthquakes, it now presents an incongruous mixture of different styles.

Guaiacol carbonate is known as duotal, the phosphate as phosphatol, the phosphite as guaiaco-phosphal; phosphotal is a mixture of the phosphites of creosote phenols.

By heating the bromate it was partially converted into the bromide, and the resulting mixture was distilled with sulphuric acid.

The usual method employed for the preparation of the gas consists in dropping bromine on to a mixture of amorphous phosphorus and water, when a violent reaction takes place and the gas is rapidly liberated.

Zinc carbonate is added to the mixture (to neutralize the acid formed), which is kept warm for some days and well stirred.

Chromic acid oxidizes it to acetic acid and carbon dioxide; potassium permanganate oxidizes it to pyruvic acid; nitric acid to oxalic acid, and a mixture of manganese dioxide and sulphuric acid to acetaldehyde and carbon dioxide.

Aeneas Tacticus in the following century mentions a mixture of sulphur, pitch, charcoal, incense and tow, which was packed in wooden vessels and thrown lighted upon the decks of the enemy's ships.

The art of compounding this mixture, which is also referred to as zrup Oaxa6vcov, or sea fire, was jealously guarded at Constantinople, and the possession of the secret on several occasions proved of great advantage to the city.

The mixture, then, was composed of such materials as sulphur and naphtha with quicklime, and took fire spontaneously when wetted - whence the name of wet fire or sea fire; and portions of it were "projected and at the same time ignited by applying the hose of a water engine to the breech" of the siphon, which was a wooden tube, cased with bronze.

The crude phosphorus is purified by melting under water and then filtering through animal black and afterwards through chamois leather, or by treating it, when molten, with chromic acid or a mixture of potassium bichromate and sulphuric acid; this causes the impurities to rise to the surface as a scum which can be skimmed off.

The reaction mixture on treatment with water yields the primary phosphine, the secondary phosphine being then liberated from its hydriodide by caustic soda.

It is probable, however, that pure phosphorous oxide vapour is odourless, and the odour of phosphorus as ordinarily perceived is that of a mixture of the oxide with ozone.

On heating they yield phosphine and leave a residue of pyrophosphate, or a mixture of metaand pyrophosphates, with a little phosphorus.

The metallic phosphites are stable both dry and in solution; when strongly heated they evolve hydrogen and yield a pyrophosphate, or, especially with the heavy metals, they give hydrogen and a mixture of phosphide and pyrophosphate.

The first is formed when 30% hydrogen peroxide reacts with phosphorus pentoxide or metaor pyrophosphoric acids at low temperatures and the mixture diluted with ice-cold water.

The second, P4S7, is obtained by heating a mixture of red phosphorus and sulphur in the proportions given by P4S7+5% P4S3, and crystallizing from carbon disulphide in which P 4 S 3 is readily soluble.

The mixture can be separated by shaking with sulphuric acid, whereupon the ortho and meta forms are converted into soluble sulphonic acids, the para form being soluble only in concentrated acid; the ortho and meta acids may be separated by crystallization of their salts or sulphonamides.

Since conhydrine is dehydrated by phosphorus pentoxide into a mixture of a and f3 coniceines, it may be considered an oxyconine.

It is a mixture of moral and ecclesiastical instruction.

Ordinary sulphuric acid, H 2 SO 4, may be prepared by dissolving sulphur trioxide in water, a reaction accompanied by a great evolution of heat; by the gradual oxidation of an aqueous solution of sulphur dioxide, a fact which probably explains the frequent occurrence of sulphuric acid in the natural waters rising in volcanic districts; or by deflagrating a mixture of sulphur and nitre in large glass bells or jars, absorbing the vapours in water and concentrating the solution.

Neither is there any advantage gained by mixing this hydrate with sulphur trioxide; for when such a mixture is concentrated by evaporation, sulphur trioxide is vaporized until the same hydrate is left.

It is evident that the "nitrous gases" present in the vitriol chamber consist essentially of a mixture of NO and N02, the latter being formed from NO by the excess of oxygen present.

Here the reactions sketched above take place, so that "chamber-acid" as already described is formed, while a mixture of gases escapes containing all the atmospheric nitrogen, some oxygen in excess, about 0.5% of the total S02, and some oxides of nitrogen.

Many attempts have been made to reduce the chamber space by apparatus intended to bring about a better mixture of the gases, and to facilitate the interaction of the misty particles of nitrous vitriol and dilute acid floating in the chamber with each other and with the chamber atmosphere.

Fuming or Nordhausen Oil of Vitriol, a mixture or chemical com pound of H 2 SO 4, with more or less S03, has been made for centuries by exposing pyritic schist to the influence of atmospheric agents, collecting the solution of ferrous and ferric sulphate thus formed, boiling it down into a hard mass ("vitriolstein") and heating this to a low red heat in small earthenware retorts.

It was soon found that the production of a mixture of SO 2 and 0 from sulphuric acid, as above described, was both too troublesome and costly, and after a number of experiments in other directions inventors went back to the use of ordinary burner-gas from pyrites and sulphur burners.

As the Badische process effects this prevention by cooling the contact apparatus by means of the gaseous mixture to be later submitted to the catalytic action, the mixture is at the time heated up to the requisite temperature, and a considerable saving of fuel is the consequence.

The roots are cut into fingers and supplemented by an allowance of concentrated food made up of a mixture of ground cakes and meal, 4 lb rising to about 1 lb; and a lb to I lb of hay per day.

Baeyer obtained what was probably a mixture of the two by heating I.

It condenses under the influence of sulphuric acid to form dodecahydrotriphenylene, C H and a mixture of ketones (C. Mannul, Ber., 1907, 40, p. 153).

Treaties and occasional very important contracts were made "blood-covenants" and inviolable by drawing a drop of blood from the little finger of each of the contracting parties, blending this with water, and both drinking the mixture out of the same cup. The forms of legal evidence were pledges, documents, witnesses and oaths.

In 1547 he won the great but barren victory of Pinkie Cleugh over the Scots, and attempted to push on the marriage and Admlnisunion by a mixture of conciliation and coercion.

Finally, the invention of a new rifle led to the introduction of a cartridge which, though it was officially denied at the moment, was in fact lubricated with a mixture of cows fat and lard.

The more usual method is to take milling soap, neutralize it with sodium bicarbonate or a mixture of fatty acids, and, after perfuming, it is aerated by mixing the hot soap with air in a specially designed crutcher.

Experience has shown that such mono-derivatives as nitro compounds, sulphonic acids, carboxylic acids, aldehydes, and ketones yield as a general rule chiefly the meta-compounds, and this is independent of the nature of the second group introduced; on the other hand, benzene haloids, amino-, homologous-, and hydroxy-benzenes yield principally a mixture of the orthoand para-compounds.

Another mixture of this type is formic acid and water.

Mixture by fusion is the general method of producing an alloy, but it is not the only method possible.

Let us suppose that a molten mixture of two substances A and B, which at a sufficiently high temperature form a uniform liquid, and which do not combine to form definite compounds, is slowly cooled until it becomes wholly solid.

If a mixture of A and B be melted and then allowed to cool, a thermometer immersed in the mixture will indicate a gradually falling temperature.

This halt in the cooling, due to the heat evolved in the solidification of the first crystals that form in the liquid, is called the freezingpoint of the mixture; the freezing-point can generally be observed with considerable accuracy.

There may be other halts in the cooling, both before and after complete solidification, due to evolution of heat in the mixture.

These halts in temperature that occur during the cooling of a mixture should be carefully noted, as they give valuable information concerning the physical and chemical changes that are taking place.

In such a diagram, a point P defines a particular mixture, both as to percentage, composition and temperature; a vertical line through P corresponds to the mixture at all possible temperatures, the point Q being its freezing-point.

It consists of two branches AC and BC, which meet in a lowest point C. It will be seen that as we increase the percentage of B from nothing up to that of the mixture C, the freezing-point becomes lower and lower, but that if we further increase the percentage of B in the mixture, the freezing-point rises.

The mixture C has a lower freezing or melting point than that of any other mixture; it is called the eutectic mixture.

Let us con sider a little more closely the solidification of the mixture represented by the vertical line Pqrs.

Consequently the temperature does not change and there is another well-marked halt in the cooling, and this halt lasts until the mixture has become wholly solid.

It is evident that every mixture except the eutectic mixture C will have two halts in its cooling, and that its solidification will take place in two stages.

At temperatures between the solidus and the liquidus a mixture is partly solid and partly liquid.

The addition of a third metal will sometimes render the mixture of two other metals homogeneous.

Ambrosius Macrobius Theodosius (c. 400) wrote a treatise on Cicero's Somnium Scipionis and seven books of miscellanies (Saturnalia); and Martianus Capella (c. 430), a native of Africa, published a compendium of the seven liberal arts, written in a mixture of prose and verse, with some literary pretensions.

It mixes with water in all proportions, the mixing being attended by a contraction in volume and a rise in temperature; the maximum contraction corresponds to a mixture of 3 molecules of alcohol and I of water.

It was found, however, that certain classes were addicted to drinking this mixture, and since 1891 the sale of such spirit has been confined to manufacturers who must purchase it in bulk from the "methylators."

Its general colour is blackish, lighter by mixture of brown or grey on the head and upper fore part of the body, with no light patch on the throat, and unlike other martens generally darker below than above.

It is insoluble in hydrochloric, nitric and sulphuric acids, but dissolves in aqua regia - a mixture of hydrochloric and nitric acids - and when very finely divided in a heated mixture of strong sulphuric acid and a little nitric acid; dilution with water, however, precipitates the metal as a violet or brown powder from this solution.

In solution minute quantities of gold may be detected by the formation of " purple of Cassius," a bluish-purple precipitate thrown down by a mixture of ferric and stannous chlorides.

Thorpe and Laurie converted potassium auribromide into a mixture of metallic gold and potassium bromide by careful heating.

The Japanese use for ornament an alloy of gold and silver, the standard of which varies from 350 to 500, the colour of the precious metal being developed by " pickling " in a mixture of plum-juice, vinegar and copper sulphate.

The separation of gold from silver in the wet way may be effected by nitric acid, sulphuric acid or by a mixture of sulphuric acid and aqua regia.

Generally the reaction mixture is allowed to cool, and the residue, which settles to the bottom of the pot, consists of gold together with copper, lead and iron sulphates, which are insoluble in strong sulphuric acid; silver sulphate may also separate if present in sufficient quantity and the solution be sufficiently cooled.

Another process consists in treating a mixture of the residue with one-quarter of its weight of calcined sodium sulphate with sulphuric acid, the residue being finally boiled with a large quantity of acid.

Its causes and results are fundamental for the study of ethnology (formation and mixture of races), of political and social history (formation of states and survival of institutions), and of political economy (mobility of labour and utilization of productive forces).

This V Olkerwanderung, as it is called by German historians, again transformed the face of Europe, resulting in the establishment of independent kingdoms and a great mixture of races and institutions.

On the plateau there are but few hills; the streams run slowly and the country is a mixture of plain and undulating ground covered by dense sdl forests.

Their conversion by St Paul added difference of religion to the causes which prevented mixture of race.

The plants are slow growers and must have plenty of sun heat; they require sandy loam with a mixture of sand and bricks finely broken and must be kept dry in winter.

Further, it is probably in the mixture of Greek, Persian and Indian deities which characterizes the pantheon of the Kushan kings that are to be sought many of the features found in Mahayanist Buddhism and Hinduism (as distinguished from the earlier Brahmanism).

The method of using these liquids is in all cases the same; a particle is dropped in; if it floats a diluent is added and the mixture well stirred.

Blomstrand, and others, especially of Marignac, proved the identity of columbium, dianium and niobium, and that ilmenium was a mixture of columbium and tantalum.

It is very probable that neptunium is a similar mixture.

It is unaffected by any acid or mixture of acids, but burns to the pentoxide when heated.

A particularly fine-grained mud is formed on the low coasts of the eastern border of the North Sea by a mixture of the finest sediment carried down by the slow-running rivers with the calcareous or siliceous remains of plankton.

Hemipelagic deposits are a mixture of deposits of terrigenous and pelagic origin.

One can look on sea-water as a mixture of very dilute solutions of particular salts, each one of which after the lapse of sufficient time fills the whole space as if the other constituents did not exist, and this interdiffusion accounts easily for the uniformity of composition in the sea-water throughout the whole ocean, the only appreciable difference from point to point being the salinity or degree of concentration of the mixed solutions.

Such, for instance, were those of Spindler and Wrangell in the Black Sea by sinking an electric lamp, those of Paul Regnard by measuring the change of electric resistance in a selenium cell or the chemical action of the light on a mixture of chlorine and hydrogen, by which he found a very rapid diminution in the intensity of light even in the surface layers of water.

The colour of sea-water as it is seen on board ship is most readily determined by comparison with the tints of Forel's xanthometer or colour scale, which consists of a series of glass tubes fixed like the rungs of a ladder in a frame and filled with a mixture of blue and yellow liquids in varying proportions.

This is well shown by taking a cylinder one-half full of acetylene and one-half of air; on applying a light to the mixture a lurid flame runs down the cylinder and a cloud of soot is thrown up, the cylinder also being thickly coated with it, and often containing a ball of carbon.

If now, after a few moments' interval to allow some air to diffuse into the cylinder, a taper again be applied, an explosion takes place, due to a mixture of carbon monoxide and air.

A good working mixture of these materials may be taken as being loo parts by weight of lime with 68 parts c arbide.

The arc is struck in a crucible into which the mixture is allowed to flow, partially filling it.

Pure crystalline calcium carbide yields 5.8 cubic feet of acetylene per pound at ordinary temperatures, but the carbide as sold commercially, being a mixture of the pure crystalline material with the crust which in the electric furnace surrounds the ingot, yields at the best 5 cubic feet of gas per pound under proper conditions of generation.

The run carbide, however, is never so rich as the ingot carbide, since an excess of lime is nearly always used in the mixture to act as a flux, and this remaining in the carbide lowers its gasyielding power.

The vessel, however, which contains this mixture has to be of earthenware, porcelain or enamelled iron on account of the free acid present; the gas must be washed after purification to remove traces of hydrochloric acid, and care must be taken to prevent the complete neutralization of the acid by the ammonia present in the gas.

The loess soil, chiefly a mixture of porous clay and carbonate of lime, forms the bluffs that border the bottom lands of the Missouri.

Let a mixture of gases contain per unit volume v molecules of the first kind, v' of the second kind, and so on.

His curious encyclopaedic work, entitled Satyricon, or De Nuptiis Philologiae et Mercurii et de septem Artibus liberalibus libri novem, is an elaborate allegory in nine books, written in a mixture of prose and verse, after the manner of the Menippean satires of Varro.

The mixture of races among the inhabitants, especially the presence of numerous Malays, who on all festive occasions appear in gorgeous raiment, gives additional animation and colour to the street scenes.
