CROOKES, WILLIAM.

On the Viscosity of Gases at High Temperatures. Received December 28, 1880, Read febiary 17, 1881.

(London, Harrison and Sons, 1881). 4to. No wrappers as extracted from "Philosophical Transactions" 1881 - Vol. 172 - Part II. Pp. 387-434, textillustr. and 4 plates (3 double-page folding). One plate showing apparatus.

First appearance of an importent paper which reports a series of experiments with the radiometer, invented 1875 by Crookes. In these experiments Crookes showed how the radiometer confirmed Maxwell's prediction that the viscosity of a gas was independent of its pressure except at the highest exhaustions.

Sir William Crookes (1832-1919) studied at the Royal College of Chemistry , London, and served there as an assistant to Hoffmann. In 1859 he founded the Chemical News and remained its proprietor and editor until his death. he early attracted attentuion by his discovery of the element thallium by spectroscopic methods. He was an active investigator in many fields of physics and contributed greatly to the advance of knowledge by his study of the radiometer and of the electric discharge in rarefied gases. -
