ANDREWS, THOMAS. - THE NATURE OF OZONE

On the Constitution and Properties of Ozone. Received May 16, - Read June 21, 1855.

(London, Taylor and Francis, 1856). 4to. No wrappers as extracted from "Philosophical Transactions" 1856 - Vol. 146 - Part I. Pp. 1-13 a. 1 lithographed plates.

First printing of Andrew's paper in which he shows, that ozone is oxygen in allotropic form.

Andrews subsequently turned his attention to the problem of the constitution of ozone. This had been investigated by a number of chemists, including Schöonbein, its discoverer. Its nature was still unknown, however, and it was by no means certain that the ozone obtained from different sources was one and the same substance; it was thought by some to contain hydrogen. Andrews says his researches extended over four or five years, and he finally reached the conclusion that all the supposed varieties of ozone were identical and that it was in fact oxygen in an altered or allotropic condition.
