Abstract
THERE is a gratifying tendency for modern general text-books on analysis to become something more than collections of tables and recipes by the extension of their scope to include other matter: thus, a text on the quantitative side will deal with the underlying physico-chemical considerations. In the present handy volume, which for the sake of brevity confines itself to the familiar arbitrary common radicles, an attempt is made to emphasise the connexion between the analytical groups and the groups of the Periodic Table, thus combining the general behaviour of an element with its analytical reactions. As an example, it is pointed out that, with one exception, those metals which are precipitated by hydrogen sulphide from acid solution occur in Nature predominantly as sulphides; this relationship, which can be extended to other insoluble compounds utilised in qualitative work, has a perfectly simple explanation, and yet is almost universally overlooked.
