[Oct., 1922.] 



of ventilating cowsheds, which is largely used in the S.W. of Scotland, is 

 described by the author as the ideal one. The use of fireclay ridge ventilators 

 is condemned. A system of lighting cowsheds whereby the hindquarters 

 of the cows are clearly visible is reconimended, and those interested in the 

 production of clean milk will profit by the study of the notes given. The 

 text dealing with the reconstruction of insanitary buildings could be improved 

 on by illustrations showing what can be done with existing walls. Whole- 

 time municipal veterinary officers are frequently called upon to draw up a 

 specification of work required in reconstructing insanitary cowsheds, but one 

 looks in vain to the work under review for assistance. Methods of reporting 

 on buildings and animals are also omitted. 



Preventive medicine is discussed in a masterly manner, and many up-to- 

 date hard facts are quoted in connection with the scheduled diseases. The 

 author is in error in stating that " in the case of Swine Fever the disinfection 

 is under the control of the lay inspectors of the Ministry of Agricultui-e, 

 the Veterinary Inspector has nothing to do with it. " Further notes on the 

 disposal of carcasses are desirable and in these days of economy it is some- 

 what surprising to see so much space devoted to Bostock's expensive method 

 of cremation. 



Tuberculosis in animals is dealt with in detail and the statement is made 

 that milk from a tuberculous udder always contains Tubercle baccilli. Some 

 of the parasites found in animals are described and much useful information 

 is given concerning their control and ei adication. 



The section on Sanitary Law is dealt with in a concise manner and herein 

 lies its weakness. Many important Acts and Orders do not receive notice and 

 important legal decisions are not supplied. While discussing law it is always 

 advisable to quote the relevant section or article. 



Although a lew points in which improvement could be made have been 

 mentioned, the book can be thoroughly recommended as a safe guide and the 

 author deserves congratulations for having condensed the subjects under 

 discussion admiiably. The publishers have performed their duty in their 

 usual thorough mannei".
