DAVY, HUMPHREY. - THE DISCOVERY OF CHLORINE DIOXYD.

Some experiments on a solid compound of iodine and oxygene, and on its chemical agencies. Read April 20, 1815. (+) On the action of acids on the salts usually called hyperoxymuriates. Read May 4, 1815. (2 papers).

(London, W. Bulmer and Co., 1815). 4to. No wrappers as extracted from "Philosophical Transactions" 1815 - Part II. Pp. 203-213 a. pp. 214-219.

First appearance of two importent papers by davy. In the second paper offered, he relates his discovery of chlorine dioxyd.

"By explosion over mercury he found that 2 vols. give from 2.7 to 2.9 of gas, and this would probably be 3 vols. if no chlorine had been absorbed by the mercury. This gas contains 2 vols. of oxygen and the remainder chlorine, hence the compound consists of 'two in volume of oxygen and one of chlorine, condensed into the space of two volumes' (ClO2). He found it to explode at about 100 deg. with more viollence than euchlorine."(Partington III, p. 57).

Together with ROBERT PORRETT "Further analytical experiments relative to the constitution of the prussic; of the ferruretted chyazic, and of the sulphuretted chyazic acids; and of their salts; together with the application of the atomic theory to the analysis of these bodies.", pp. 220-230 a. 2 tables, one folding.
