The records of convocation in Chicheley's time are a curious mixture of persecutions for heresy, which largely consisted in attacks on clerical endowments, with negotiations with the ministers of the crown for the object of cutting down to the lowest level the clerical contributions to the public revenues in respect of their endowments.
His investigations on vinegar-making revolutionized that industry, and he showed how, instead of waiting two or three months for the elaboration of the process, the vinegar could be made in eight or ten days by exposing the vats containing the mixture of wine and vinegar to a temperature of 20 to 25° C., and sowing with a small quantity of the acetic organism.
It may be obtained as a dark brown amorphous powder by placing a mixture of io parts of the roughly powdered oxide with 6 parts of metallic sodium in a red-hot crucible, and covering the mixture with a layer of well-dried common salt.
Boron hydride has probably never been isolated in the pure condition; on heating boron trioxide with magnesium filings, a magnesium boride Mg 3 B 2 is obtained, and if this be decomposed with dilute hydrochloric acid a very evil-smelling gas, consisting of a mixture of hydrogen and boron hydride, is obtained.
Boron nitride BN is formed when boron is burned either in air or in nitrogen, but can be obtained more readily by heating to redness in a platinum crucible a mixture of one part of anhydrous borax with two parts of dry ammonium chloride.
The conceptions of "element," "compound" and "mixture" became more precise than they had been hitherto; in an element all the atoms are alike, in a compound all the molecules are alike, in a mixture there are different kinds of molecules.
With this or a mixture of horse-dung, loam, old mushroom-bed dung, and half-decayed leaves, the beds are built up in successive layers of about 3 in.
A mixture of the melanistic with the albinistic type will of course give rise to parti-coloured cats.
In order to get rid of hydrogen, some oxygen is added to the helium, and the mixture exploded by an electric spark.
Potash solution converts it into a mixture of potassium cyanide and cyanate.
By strongly heating a mixture of boron trioxide and aluminium, protected from the air by a layer of charcoal, F.
Thenard and is best obtained by heating a mixture of the trioxide and fluorspar with concentrated sulphuric acid.
A-propylene glycol, CH 3 CH(OH) CH 2 OH, a liquid boiling at 188° to 189°, and obtained by heating glycerin with sodium hydroxide and distilling the mixture; and trimethylene glycol, CH 2 OH CH 2 CH 2 OH, a liquid boiling at 214° C. and prepared by boiling trimethylene bromide with potash solution (A.
Thus the most prominent subdivision of the older school, the Taittiriyas, in their Samhita, have treated the main portion of the ceremonial in this promiscuous fashion, and to add to the confusion they have, by way of supplement, put forth a so-called Taittiriya-brahmana, which, so far from being a real Brahmana, merely deals with some additional rites in the same confused mixture of sacrificial formulae and dogmatic explanations.
Galen believed in the doctrine of humours originated by Hippocrates, which supposes the condition of the body to depend upon the proper mixture of the four elements, hot, cold, moist and dry, and that drugs possess the same elementary qualities, and that on the principle of contraries one or other was indicated, e.g.
Phenol dissolves readily in concentrated sulphuric acid, a mixture of phenol-orthoand -para-sulphonic acids being formed.
The right and left halves are completely divided by septa, no mixture of the venous and arterial blood being possible, an advance upon reptilian conditions, even the highest.
Boron chloride BC1 3 results when amorphous boron is heated in chlorine gas, or more readily, on passing a stream of chlorine over a heated mixture of boron trioxide and charcoal, the volatile product being condensed in a tube surrounded by a freezing mixture.
It is obtained by the oxidation of orthophenylene diamine with ferric chloride; when a mixture of para-aminodimethylaniline and meta-toluylenediamine is oxidized in the cold, toluylene blue, an indamine, being formed as an intermediate product and passing into the red when boiled; and also by the oxidation of dimethylparaphenylene diamine with metatoluylene diamine.
Nicotine may be recognized by the addition of a drop of 30% formaldehyde, the mixture being allowed to stand for one hour and the solid residue then moistened by a drop of concentrated sulphruic acid, when an intense rose-red colour is produced (I.
Notre-Dame d'Afrique, a church built (1858-1872) in a mixture of the Roman and Byzantine styles, is conspicuously situated, overlooking the sea, on the shoulder of the Bu Zarea hills, m.
Meta-aminophenol is prepared by reducing metanitrophenol, or by heating resorcin with ammonium chloride and ammonia to 200° C. Dimethyl-meta-aminophenol is prepared by heating meta-aminophenol with methyl alcohol and hydrochloric acid in an autoclave; by sulphonation of dimethylaniline, the sulphonic acid formed being finally fused with potash; or by nitrating dimethylaniline, in the presence of sulphuric acid at 0° C. In the latter case a mixture of nitro-compounds is obtained which can be separated by the addition of sodium carbonate.
The chamber has a safety value at the top of its vault, which is so balanced that the least surplus pressure from within sends it up. The first puff of sulphur vapour which enters the chamber takes fire and converts the air of the chamber into a mixture of nitrogen and sulphur dioxide.
I tried flour also; but have at last found a mixture of rye and Indian meal most convenient and agreeable.
These fine jet droppers with a mixture of alcohol and water have proved very effective for balloon observations.
Sainte-Claire Deville obtained a grey product, from which, on dissolving out the aluminium with sodium hydroxide, they obtained a crystalline product, which they thought to be a modification of boron, but which was shown later to be a mixture of aluminium borides with more or less carbon.
