‘The taint preduck camphor-chloralhydrate 
There is a pharmaceutical preparation, known under thes name of © 
Chloralum camphoratum, which is composed of equal parts by weight of 1 
: chloral hydrate and presents itself in the form of a highly viscous liquid. In 
ie to ascertain whether the components form a solution or an additive product, 
3 kalotos') thermically analyzed the mixture, determining the sol. ps. of varying
