and air and report experiments to determine the more common 
forme and decomposition products.— Ber. d. pharm. Gesellsch., 1905,

Cushing, E. W., discusses the decomposition of chloroform vapor 
by the flame of illuminating gas and quotes several cases of fatal and 
of untoward results recorded in the literature. — Y. Y. M. J., 1905, v.

Imbert, L. (from L’Union pharm. 1905), reviews the work done 
on the decomposition of chloroform vapor. He finds that at red 
heat chloroform is decomposed into C, HC1, and Cl 2 . In the pres- 
ence of air the carbon is decomposed into carbon monoxide. — Pharm.
