the wife and children secure, depend upon the efficiency with which the household 

 turns the wage income into economic good. The home can become responsible 

 for malnutrition and insanitary living by improper preparation and waste of food. 

 The little book is interesting and instructive.

Microscopy of Vegetable Foods, with Special Reference to the Detection of 

 Adulteration and the Diagnosis of Mixtures. By Drs. Andrew L. Winton, 

 Josef Moeller, and Kate Winton. [Second Edition. Pp. xiv + 701, 

 with illustrations.] (New York : John Wiley & Sons; London : Chapman 

 & Hall, Ltd. Price 27s. 6d. net.) 



THE importance of food-microscopy is fully recognised, and the second edition of 

 the comprehensive work on the subject by the present authors is evidence of the 

 value of their previous work. The book is intended primarily for the student and 

 worker, as well as the public analyst. The account of the method of preparing 

 the materials for examination, and the description of the chief histological elements 

 will be useful, but the volume presupposes some preliminary training in botanical 

 science. The microscopical characters of the principal vegetable foodstuffs, as 

 well as those of every common adulterant or impurity, are given in full detail, 

 which makes their recognition easy. The excellent character of the drawings 

 throughout the volume should further assist in countering and limiting the scope 

 of the perverse ingenuity of the adulterant. The volume should be in the hands 

 of every public analyst.

Catalogue of the Serial Publications possessed by the Geological Com- 

 mission of Cape Colony, the Royal Observatory, the Royal Society of 

 South Africa, the South African Association for the Advancement of 

 Science, the South African Museum, and the South African Public 

 Library. With an Appendix containing a List of the Serials in the Bolus 

 Herbarium of the South African College. [Pp. 54.] (Published by the 

 Trustees of the South African Public Library, Capetown, 191 2.) 



THE printed work of South African geologists, and no doubt that of specialists in 

 other branches of science, frequently contains the plaint that they are hampered 

 by the lack of literature or by its inaccessibility. A partial remedy for this defect 

 is attempted by the publication of this catalogue, which lists scientific and other 

 periodicals in the possession of several South African public bodies. The list is 

 in alphabetical order, place names are emphasised by italic type, and the volumes 

 in possession of the six public bodies are noted in six parallel columns following 

 the name of the periodical. The letters inc., denoting " incomplete," occur with 

 distressing frequency throughout the list. - In geology, for example, even the 

 Transactions of the Geological Society of South Africa are incomplete, not to 

 speak of other well-known periodicals. It is to be hoped that all interested in 

 South African scientific work will note the appeal made at the end of the catalogue, 

 and assist in filling up the numerous gaps.
