or thinner the conductor the greater the resistance and the less 

 the flow of current." Thus endeth the discussion on "Electrical 

 Measurements." This fault of inaccuracy, glaring as it is, is 

 of minor importance, however, compared with another fault 

 which mars the book. Instead of presenting the data obtained 

 from the experiments in such a way as to lead the student to 

 reason on the facts presented and so to develop the scientific 

 attitude and habit of thought, the author presents to the student 

 the conclusions ready made, and thus anticipates and forestalls 

 all independent thought, making scientific training impossible.

In view of the scope of a work of this character it is quite 

 impossible for a man of average training in the subject to pass 

 a critical judgment upon the accuracy of all phases of the subject 

 matter. In glancing through a book for this purpose one natur- 

 ally pauses at the topics with which one feels especially familiar 

 and subjects the statements of the author to scrutiny. Judged 

 by such a method, the book is satisfactory and up to date with 

 few exceptions. 



The space devoted to Von Pirquet's cutaneous tuberculin re- 

 action might better have been allotted to a discussion of the 

 intradermal test for tuberculosis in cattle as described by Moussu 

 and Mantoux. Their work was confirmed by Ward and Baker 

 in a paper published in the Proceedings of the American Veteri- 

 nary Medical Association for 1910 and in the American Veteri- 

 nary Review for November, 1910, page 184. It is hoped that 

 by the time the book is revised the intradermal test will have 

 won more general recognition. 



A review is not quite complete without a criticism of the use 

 of at least one word. With all humility for my own short- 

 comings it is pointed out that the author uses the word epidemic 

 instead of epizootic on page 302. On the same line Dr. Brim- 

 hall's identity is masked by an unfortunate typographical error. 

 Elsewhere the spelling of Johne is distorted by the addition of s. 



In discussing antirinderpest serum the author accepts, as have 

 many others, the statement of Kolle and Turner that "An injec- 

 tion of 50 to 100 cubic centimeters of the serum so secured will 

 protect an animal against infection for a space of from 2 to 4
