Laboratory Manual in General Microbiology. Ward Giltner. Pp. 

 418. John Wiley and Sons. 1916. 



It is refreshing to have a laboratory guide for the study of micro- 

 organisms with a new title. This Manual is the result of the teaching 

 experience of the author and co-workers at the Michigan Agricultural 

 College and aims to be a guide for the teaching of general microbiology. 



I suspect that many teachers experience the same difficulty the 

 reviewer has felt in adapting another's laboratory directions to his 

 own classroom work. The present Manual will be found extremely 

 helpful and suggestive in the hands of the teacher but its wide accept- 

 ance as a class book seems doubtful, partly because of its length, and 

 partly because of its lack of emphasis on any particular field or group. 



The Manual is divided into three parts: Part I, General Morphologi- 

 cal and Cultural Methods with 53 exercises; Part II, Physiology of 

 Microorganisms with 33 exercises; Part III, Applied Microbiology, 

 including 1 exercise on Air, 4 exercises on Water and Sewage, 10 exer- 

 cises on Soil, 10 exercises on the Dairy, 1 exercise on Plant Micro- 

 biology, and 14 exercises on Animal Diseases and Immunity. The 

 Appendix is of great value, including directions for the preparation 

 of special media, stains, various tables and other data. 



The illustrations are admirable and an excellent selection of perti- 

 nent references is given at the end of each exercise. 



The book may be highly commended to teachers, who will cull 

 from it many valuable suggestions, and when sufficiently extensive 

 courses in general microbiology are offered it may well be adopted in the 

 classroom.
