designed as laboratory guides. The first, by Dr. Moore, gives a series of 

 sixty-four lessons in bacteriological technique, covering the general topics which 

 students study in practical bacteriology. The Laboratory Guide, by Frost, is 

 more specially designed as a laboratory note-book in the study of bacteriology. 

 About half of it is taken up with blanks to be used by students in describing species 

 of bacteria, while the other half is devoted to various exercises in general bacteri- 

 ology. The Practical Bacteriology, by Curtis, is a somewhat more extended work, 

 and contains a great deal more information than the other two books. It is full of 

 illustrations of apparatus and laboratory devices, as well as of the chief 

 species of bacteria. In addition to laboratory technique it gives a large amount 

 of information in regard to various bacteria, and their relations to disease. This 

 work is especially useful as giving the student not only a knowledge of laboratory 

 technique, but also a great amount of information in regard to the significance 

 of the organisms which he is studying. The work is especially full in its descrip- 

 tions of some of the more unusual forms of bacteria. Ringworms and cancer 

 are considered in very considerable detail, with the purpose of indicating lines 

 of research for advanced students. A more detailed study of the Actinomyces 

 and its allies is given than can be found in most works of bacteriology. For 

 these reasons the student will obtain from the work much more than would be 

 indicated by a common course in laboratory bacteriology. h. w. c.

 63 Ark. Agri. Exp. Sta. clusion as to whether the bovine and 



human tubercle bacillus are, as has been claimed by Smith, different in 

 their pathological properties. For this purpose he experiments not only with 

 cattle, but with other animals. The result of the experiment is not only to 

 verify Smith's conclusions, but to extend them. He finds that the bovine 

 bacillus is always more virulent than the human bacillus, and that this is true 

 whether the tests are made on cattle, sheep or pigs. So far as his experiments 

 go, they appear to indicate that the bovine bacillus is more virulent for all sus- 

 ceptible animals. It certainly appeared to be for all animals experimented with, 

 and the author infers that it is also more virulent for men. This inference, 

 which is of extreme importance, the author recognizes, however, as not yet 

 proved. h. w. c.
