2s. 6d. net. London: Balli~re, Tindall and Cox. 1906. This little book contains 500 questions which have been set at Public Health examinations. They are divided into sections according to their subject matter. There can be no doubt of the value of a familiarity with examination questions, not only in view of the examination merely, but as a method Of testing one's precise knowledge of a subject as opposed to a mere generalized idea. W e Can recommend this collection, and can confidently state that if a candidate can accurately answer all these questions, he need not fear the ordeal which lies before him. THE STUDENT'S HYGIENE.

CORRESPONDENCE. THE FAT CONTENT IN MILK, To the Editor of "Public Health."
SIR,--I think the following analyses of milks are of interest. A sample was taken in the city during the course of delivery, and its analysis was : Solids not fat, 9"18 ; Fat, 2"65 ; Water, 88"17 ; the farm from which*he milk came was visited by Mr. J . K. Crawshaw, the Sanitary Inspector. He found two cowsheds, one containing eight, and the other ten cows. These cows were milked in his presence. The milk of the first eight cows (including the strippings)was .mixed, and its analysis gave the following figures : Solids not fat, 8-65 ; Fat, 2"85; Water, 88"50. The same process was gone through with the ten Cows in the second shed, and the analysis gave : Solids not fat, 8"73 ; Fat, 2"97 ; Water, 88"30. I think it is unusual for a mixed milk (known to be genuine) of eight cows to give an analysis below the Board of Agriculture standard. Yours truly, March 26tk, 1906. E.W. Rees Jones, M.D.
