Abstract
THERE is probably no one who has reason occasionally to take a photograph, whether for simple pleasure or for scientific or business purposes, without having at command a well-equipped photographic laboratory, who does not consider the preparation of the various solutions required as a messy, troublesome and tedious performance. And the getting of some of the chemical substances in a fit state for use is a very real difficulty, only to be got over in some cases by procuring the original packages or bottles as issued by the manufacturer, and containing perhaps twenty times as much as is required. We have known several cases where so common a substance as sodium sulphite has been obtained only after seeking for it at several druggists, and other cases where the work was spoilt by reason of the gross impurity of the material.
