A Laboratory Guide In Elementary BacterioiOKy * 



The third revised edition of W. D. I'rost's " Laboratory Bac- 

 teriology," a handy volume of four hundred pages and forty or 

 more illustrations, has just been published by the Macmillan Co. 

 Previous editions of this work have been used with great success- 

 by Professor Frost at the University of Wisconsin, and in the 

 present edition only such changes have been made as are neces- 

 sitated by the rapid progress of this science and improvements 

 in methods employed in its study and application. 



The plan of the work remains the same. In the first part,, 

 requiring a half year for its completion, the general subject of 

 bacteriology is taken up in the following order : technique, phys- 

 iology, taxonomy, representative nonpathogenic forms and bac- 

 teriological analysis. The second part, dealing with medical" 

 bacteriology, is an application of the knowledge and skill gained 

 in the first to a rather serious study of pathogenic bacteria, more- 

 recent and more technical methods being used in connection with 

 many of the forms treated. 



The author regards directions for laboratory exercises as fun- 

 damental. These directions have a constant and a variable part, 

 the latter subject to modification as changes become necessary in 

 the kind of organism, the kind of medium, the temperature, etc. 

 An attempt is made to observe a logical order in the experi- 

 ments, though the time required for individual experiments may 

 vary wideh'. Cultural observations are conveniently recorded by 

 means of charts, with which the book abounds. 



The system of classification adopted is that of Migula, which 

 is quite generally used. Many of the older names are to be 

 looked for in the list of .synonyms. Like all other good labora- 

 tory guides, Professor Frost's book is well supplied with lists of 

 apparatus, te.xts, appendices, etc., and with helpful suggestions- 

 relative to their use. Appendix A is a key to the most common 

 forms of bacteria usually encountered by the student.
