intelligible to a beginner, \vho is plinigctl ob iiiiiin into a subject which lit. really cannot understand without tlie npijlicatioii of this la\v, by mean.< o f which the \vliole subject ilia!- lie niatlc. Ijcautiiully clear aiid siniple. Fro111 tlie purely analytical point (.)f vieiv. the most interesting colitributioii by Cottger is the use o i a systematic grouping of anions through the solubilities of the harium, lead and silver salts. F o r those ivho still favor the converting of the acids into soluble alkali salts as preliminary to the acid analysis. this grouping v.iI1 probably prove \velcome. I n the esptrience of the ivriter, the change into alkali salts is subject to so inany complications and exceptions ;ind the gain hy such a grouping is often so small, that it has been tliscartletl except for the so-called “insoluhle” (in acid) unknowns antl all tests for acids, group ant1 individual, are no\v carried out in acid solutions. ivithoat removing tlie cathions : most of the iniportant acid tests arc, as it is, carried out i n acid solutions and the results of tlie analysis for metal ions, with the solubilitites of solid 1111knoiviis ant1 the reaction of solutions, \vi11 usually give very considerablc information as to what groups oi acids may be present.

F o r years past this book has occupied a unique place as a treatise o : ~ chemistry antl although entitled Pliarniaceutical Chemistry ant1 containing much that is useful to the pharinacist it is really a hooli of the greatest value to chemists in general. -4s a book of refercncc it is of especial value as it contains a vast amount of information aiid is somewhat unique in that not a little part of the information is of the unconimon sort that oae is not apt to find included in a single‘book. T h e part under review is the first section of tlie first volume of the fifth etlitioii ivhich comprises the
