Abstract

As an introduction to the subject, this book doubt less covers the requirements of students of pharma ceutical chemistry. It does not, however, in matters of detail, arouse the reviewer's enthusiasm. The introduction of unusual abbreviations is confusing; the arithmetical examples are frequently expounded in an unnecessarily elementary manner the use of exactly normal solutions, instead of the employment of a factor is directed; the explanation of the use of excess of free acid in permanganate titrations is incomplete, so as to be quite misleading; the use of the symbol O3, except to indicate a molecule of ozone, is to be deprecated; the standardisation of N-sulphuric acid by titrating 10 c.c. with “recently prepared and standardised N-potassium or sodium hydroxide” is open to obvious criticism. In addition to the usual in organic volumetric exercises, the analysis of sugars, oils, alkaloids, urea, formaldehyde, and organic nitrites is described, and a short section is devoted to the principles underlying the determination of hydrogen ion concentration.
