Excerpt from Laboratory Studies in Chemistry One of the chief devices I have employed in attempting to give greater educational value to the work is classification. For instance, the facts which relate to some central topic such as the action of soluble hydroxides on salt solutions, or the effect of heat upon carbonates, are not scattered through the book in a wholly aimless way: they are organized into a compact laboratory exercise which serves, once for all, to make the matter clear. Examples of this general principle of ar rangement will be found in the exercises numbered 14, 22, 31, 37, 58, 59, and others.
