Página 120 - ... manufacture of it and the residual oil I have described, on a commercial scale, I have devoted a great deal of time to the study of those conditions which are calculated to lead to the most desirable results. In this attempt I have received much help from Mr. J. Brown, FCS, which I have the pleasure to acknowledge.
Página 270 - A cup-shaped radiometer similar to the above, but having the convex surfaces black and the concave bright. Light shining on this instrument causes it to rotate rapidly, the convex black being repelled. No movement is produced on letting the light shine on the bright concave surface, but good rotation is produced when only the black convex surface is illuminated.

Página 36 - If, as we doubt not, Mr. Rich wishes to render his note-book really useful to analysts, he will agree with us that every step in a novel analytical method should be fully described. A great part of the matter given relates to the adulteration of food and drugs, and must have already come under the notice of the majority of chemists in this country. The fad that certain impure ammonia turns a "gooseberry red colour " on admixture with nitric acid is not a recent observation. To our certain knowledge...
Página 92 - ... are we, with Angstrom, to attribute this line to a fluorescent or phosphorescent light produced by the electrical discharge to which the aurora is due ? This question awaits further observations before it can be definitely settled, as does also that of the source of the remarkable green line which ;s everywhere conspicuous in the solar corona.
Página 101 - Respecting this colour-change, we make out : — (1) that it arises from increased structural absorption with elevation of temperature, the more refrangible increment increasing at a greater rate than the less refrangible ; and (2) that the only necessary concomitant is alteration of atomic potentiality — a change from the white towards the black end of the metachromatic scale signifying atomic recession, and a change from the black towards the white end, atomic approach. (1) In support of this...
Página 270 - ... attracted. These experiments show that the repulsive action of radiation on the convex side is about equal to the attractive action of radiation on the concave side, and that the double speed with which the fly moves when no screen is interposed is the sum of the attractive and repulsive actions.
