Its vapour is spontaneously inflammable when exposed to air.
Monoclinic sulphur, obtained by crystallizing fused sulphur, melts at I 19.5°, and admits of undercooling even to ordinary temperatures, but contact with a fragment of the rhombic modification spontaneously brings about the transformation.
The soldiers, swinging their arms and keeping time spontaneously, marched with long steps.
All colours are complementary, or go in pairs; each pair makes up the whole activity of the retina, and so is equivalent to white; and the two partial activities are so connected that when the first is exhausted the other spontaneously succeeds.
By the action of zinc methyl on ethyl borate, in the requisite proportions, boron trimethyl is obtained, thus :-2B(OC2H5)2+ 6Zn(CH 3) 2 =2B(CH 3) 3 +6Zn< OC2H5 as a colourless spontaneously inflammable gas of unbearable smell.
That conviction he put into practice with extreme rigour during the thirty years of his reign (1825-55), endeavouring by every means at his disposal to prevent revolutionary ideas from germinating spontaneously among his subjects and from being imported from abroad.
In other words, are these organisms not spontaneously generated?
It is difficult to believe that this work of Diophantus arose spontaneously in a period of general stagnation.
Tumours appear to arise spontaneously, i.e.
Returns spontaneously to its fine-grained ductile state (cooling past Ara does not have this effect); or by breaking up the coarse grains by mechanical distortion, e.g.
The slurry, in drying on the floor of the flue, forms a fairly tough cake which cracks spontaneously in the process of drying into rough blocks suitable for loading into the kiln.
It is found, more especially in the case of organic compounds, that if a substance which oxidizes readily at ordinary temperature be mixed with another which is not capable of such oxidation, then both are oxidized simultaneously, the amount of oxygen used being shared equally between them; or in some cases when the substance is spontaneously oxidized an equivalent amount of oxygen is converted into ozone or hydrogen peroxide.
The fact is that the uniformity of nature stands to induction as the axioms of syllogism do to syllogism; they are not premises, but conditions of inference, which ordinary men use spontaneously, as was pointed out in Physical Realism, and afterwards in Venn's Empirical Logic. The axiom of contradiction is not a major premise of a judgment: the dictum de omni et nullo is not a major premise of a syllogism: the principle of uniformity is not a major premise of an induction.
The war began in Massachusetts, troops from New England flocking to the neighbourhood of Boston almost spontaneously; but the resistance, if it was to be effective, must have the support of the colonies to the southward, and the Virginia colonel who was serving on all the military committees of Congress, and whose experience in the Braddock campaign had made his name favourably known in England, was the obvious as well as the politic choice.
In this connexion it is very interesting to observe that Messrs Sutton of Reading find that the seedlings of many of the varieties of potato that occur spontaneously in different parts of America come quite true to type from seed.
In the less exposed localities, on northern slopes and sheltered valleys, the European forms become more numerous, and we find species of alder, birch, ash, elm, maple, holly, hornbeam, Pyrus, &c. At greater elevations in the interior, besides the above are met Corylus, the common walnut, found wild throughout the range, horse chestnut, yew, also Picea Webbiana, Pinus, excelsa, Abies Smithiana, Cedrus Deodara (which tree does not grow spontaneously east of Kumaon), and several junipers.
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.
450) by the action of potash upon phosphorus, the gas so prepared being spontaneously inflammable.
Some time later Davy, by heating phosphorous acid, obtained a phosphoretted hydrogen which was not spontaneously inflammable.
It burns with a brightly luminous flame, and is spontaneously inflammable at about too° C. When mixed with oxygen it combines explosively if the mixture be under diminished pressure, and is violently decomposed by the halogens.
It crystallizes in colourless cubes, is deliquescent, and often inflames spontaneously on exposure to air.
They oxidize very rapidly on exposure, in many cases being spontaneously inflammable.
It slowly reacts with cold water to form phosphorous acid; but with hot water it is energetically decomposed, giving much red phosphorus or the suboxide being formed with an explosive evolution of spontaneously inflammable phosphoretted hydrogen; phosphoric acid is also formed.
It spontaneously inflames in air or oxygen; and when the gas is issuing from a jet into air the flame is greyish green, with a faintly luminous and yellow tip; the flame is probably one of the coldest known.
We must have willed thus spontaneously first, otherwise we could not know, before our reflective volition, that we could will and act.
This view of liberty of will is the only one in accordance with the facts of humanity; it excludes reflective volition, and explains the enthusiasm of the poet and the artist in the act of creation; it explains also the ordinary actions of mankind, which are done as a rule spontaneously and not after reflective deliberation.
It may be that we first of all of'h primitively or spontaneously affirm cause, substance, sophy.
He seeks to trace the steps which the reason has spontaneously and consciously, but irreflectively, followed.
In 1876 this policy revived as a matter of course in the cabinet, and as spontaneously, though not upon a first provocation, became popular almost to fury.
Passing on to Anselrn (1033-1109), we observe that the Augustinian doctrine of original sin and man's absolute need of unmerited grace is retained in his theory of salvation; he also follows Augustine in defining freedom as the " power not to sin "; though in saying that Adam fell " spontaneously " and " by his free choice," though not " through its freedom," he has implicitly made the distinction that Peter the Lombard afterwards expressly draws between the freedom that is opposed to necessity and freedom from the slavery to sin.
On distillation of equal parts of dry potassium acetate and arsenious oxide, a colourless liquid of unbearable smell passes over, which is spontaneously inflammable and excessively poisonous.
What Cousin finds psychologically in the individual consciousness, he finds also spontaneously expressed in the common sense or universal experience of humanity.
It is a colourless liquid, slightly soluble in water, and is spontaneously inflammable.
Fermentation is induced spontaneously by the yeast cells which are always present in large numbers in the grape itself.
The oil for ink-making is prepared by heating it in an iron pot up to the point where it either takes fire spontaneously or can be ignited with any flaming substance.
It is a very powerful oxidant; a mixture of potassium chlorate and sugar in about equal proportions spontaneously inflames when touched with a rod moistened with concentrated sulphuric acid, the chlorine peroxide liberated setting fire to the sugar, which goes on burning.
It spread from Pali to the province of Meywar, but died out spontaneously in the hot season of 1837.
If left, they usually suppurate and open outwards by sloughing of the skin, but they may subside spontaneously, or remain hard and indurated.
The free acid is not known; by the addition of the potassium salt to 50% acetic acid at - 20° C., the acid anhydride, benzene diazo oxide, (C6H5N2)20, is obtained as a very unstable, yellow, insoluble compound, exploding spontaneously at o° C. Strong acids convert it into a diazonium salt, and potash converts it into the diazotate.
Passing from Moleschott to Lyell's view of the evolution of the earth's crust and later to Darwin's theory of natural selection and environment, he reached the general inference that, not God but evolution of matter, is the cause of the order of the world; that life is a combination of matter which in favourable circumstances is spontaneously generated; that there is no vital principle, because all forces, non-vital and vital, are movements; that movement and evolution proceed from life to consciousness; that it is foolish for man to believe that the earth was made for him, in the face of the difficulties he encounters in inhabiting it; that there is no God, no final cause, no immortality, no freedom, no substance of the soul; and that mind, like light or heat, electricity or magnetism, or any other physical fact, is a movement of matter.
Caesar-worship as an organized cult developed spontaneously in many provincial towns during the reign of Augustus, and was fostered by him and his successors as a means of promoting in these centres of vigour and prosperity a strong loyalty to Rome and the emperor, which was one of the firmest supports of the latter's power.
