All remaining impurities, including the excess of oxygen, can then be taken out of the gas by Sir James Dewar's ingenious method of absorption with charcoal cooled in liquid air.
Dewar 's soulful vocals really blend well with the rock riffs.
The process patented by Dewar and Redwood in 1889 consists in the use of a suitable still and condenser in free communication with each other - i.e.
In 1866 Sir James Dewar proposed an unsymmetrical form (II); while in 1867, A.
CH CH HC, N CH HC CH HC HC HC Hcch Hc Ch Ch Kekule t i Dewar Ladenburg One of the earliest and strongest objections urged against Kekule's formula was that it demanded two isomeric ortho-di-substitution derivatives; for if we number the carbon atoms in cyclical order from i to 6, then the derivatives 1.2 and 1.6 should be different.'
The third formula is based on Dewar's benzene formula, which we have seen to be incorrect.
In 1882 Claus suggested a combination of his own and Dewar's benzene formulae.

It may be remarked that, whereas Fleming and Dewar employed the ballistic method, their specimens having the form of rings, Honda and Shimizu worked magnetometrically with metals shaped as ovoids.

Fleming and Dewar determined the susceptibility of liquid oxygen (Proc. Roy.
Fleming and Dewar give for the susceptibility the values-13.7 X 6 at 15° C. and - 15.9X 10 -6 at - 182°, the latter being approximately equivalent to KX Io 6 = - 1.62.
Putting t°= - 182 in the equation given above for Curie's results, we get K X Io 6 = - 1.66, a value sufficiently near that obtained by Fleming and Dewar to suggest the probability that the diamagnetic susceptibility varies inversely as the temperature between-182° and the melting-point.

Another relic was the saint's staff or crozier, which became known as the coygerach or quigrich, and was long in the possession of a family of the name of Jore or Dewar, who were its hereditary guardians.

Dewar and Jones suggest that in the latter reaction it is the metallic nickel which is probably the reducing agent effecting the change, since it is only dissolved in any quantity when the anthracene hydrocarbon is produced.
This work to an important extent prepared the way for the "smokeless powders" which came into general use towards the end of the 19th century; cordite, the particular form adopted by the British government in 1891, was invented jointly by him and Professor James Dewar.
Dewar and H.
Dewar and Fleming, working at very low temperatures, were compelled to use the platinum thermometer, and expressed their results in terms of the platinum scale.
Noll's values apply to the temperature of +Ioo° C., Dewar and Fleming's to that of -Ioo° C., approximately.
A number of similar deviations at temperatures below o° C. were found by the writer in reducing the curves representing the observations of Dewar and Fleming (Phil.
It would appear, for instance, according to the observations of Dewar and Fleming, that the value of s for iron is positive below - 150° C., at which point it vanishes.

Polymeric material was violently ejected from the Dewar flask.
Dewar led him to see the true dynamical explanation of the Crookes radiometer in the largeness of the free path of the molecule of the highly rarefied air.
He admitted the possibility of the formulae of Kekule, Claus, Dewar and Ladenburg, although as to the last di-trimethylene derivatives should be possible reduction products, being formed by severing two of the prism edges; and he attempted to solve the problem by a systematic investigation of the reduced phthalic acids.
The relative merits of the formulae of Kekule, Claus and Dewar were next investigated by means of the reduction products of benzene, it being Baeyer's intention to detect whether double linkages were or were not present in the benzene complex.
