Tuberculosis in market milk of Chicago, F. O. Tonney (Jour. Amcr. Med. 

 .Issnc. 55 (1910), Ao. 15, pp. 1252-1255). — In an address at the meeting of the 

 American Medical Association in June, 1910, the author reports details of an 

 investigation of the milk supply of Chicago. 



Inoculations were made on guinea pigs with 163 samples of milk, with the 

 following results: "Of these, 51 caused the death of all the animals injected 

 from acute infections within 3 weeks, before diagnosis of tuberculosis was 

 possible. Eliminating these as lost, there remain 112 available for the series, 

 of which 10, or 8.9 per cent, proved tuberculous. Of 144 samples of raw milk, 

 49 were lost within 3 weeks, leaving 96 available for consideration. Of these, 

 10 specimens, or 10.5 per cent, were found tuberculous. Of 19 pasteurized 

 samples, 2 were eliminated, leaving 17 for consideration. None of the pasteur- 

 ised samples caused tubei'culosis in the animals injected." 



Report to the local government board on American methods for the con- 

 trol and improvement of the milk supply, A. Eastwood (Rpts. Local Govt. 

 B(L [67. Brit.]. Pub. Health and Med. Matters, n. ser., 1909, 'So. 1, pp. SO). — This 

 is a report on the methods adopted in different States to control bovine tubercu- 

 losis, and on the action of the British local health authorities in trying to 

 insure a sanitary supply of commercial milk. * 



The Manchester milk supply from a public health point of view, S. Del6- 

 piNE (London and Manchester, 1910, pp. 50, charts 3). — From the public health 

 point of view, this paper discusses the importance of regulating the milk 

 supply and presents in a popular manner the data and conclusions contained in 

 an article previously noted (B. S. R., 23, p. 81). 



Notes on the sterilization of milk by means of ultraviolet light, P. H. 

 RoMER and T. S.\mes (Hyg. Rundschau. 20 (1910), Xo. 16. pp. S73-S77). — Sev- 

 eral experiments are briefly reported on sterilizing milk with ultraviolet rays. 



The effectiveness as a germicide increased with the length of time treated. 

 The milk acquired an acrid taste at the end of 2i hours, although it was not 

 completely sterile at that time. The oxidase reaction was destroyed, but the 

 Schardinger reductase reaction was not affected unless the milk was treated 

 for a considerable length of time. The ultraviolet rays lowered the iodin num- 

 ber of butter, and to a less extent that of cream. Because of the destruction 

 of the oxidase, the sterilization of milk by ultraviolet rays is considered of 

 doubtful value from a dietetic standpoint. See also another article by the 

 authors on page 709 of this issue.

An act to provide for the protection of dairymen. — The Babcock test
