The variation in the pathogenic power of cultures from different species of animals 

 was very marked. 



The present aspect of the tuberculosis problem in the United States, S. A. 

 Knopf {Jour. Amer. ^fe(l Assoc, 39 {1902), Xos. 21, pp. 1309-1314; 22, pp. 1367-1373, 

 Jigs. 16). — Circular letters of inquiry were sent to various parts of the different States 

 and Territories of this country for the purpose of learning the extent and nature of 

 laws for the control of tuberculosis. The answers received to these inquiries are 

 summarized by the author. From a study of this summary it is apparent that a 

 great lack of interest i:)revails in many States and cities Avith regard to the danger of 

 transmission of tuberculosis from animals to man or from one individual to another. 



Recent investigations concerning the relation of human and bovine tuber- 

 culosis, D. v.. Salmon {.Tour. Aiuer. Med. Assoc, 39 {1902), No. 25, pp. 1571-1574)- — 

 Notes are given on recent experiments and observations which indicate the inocula- 

 tion of monkeys with bovine tubercle bacilli, and the transmission of tuberculosis 

 from man to cattle and from cattle to man. Statistics are given concerning tul)ercu- 

 losis among children who drink cows' milk, and brief notes are presented on Euro- 

 pean and American customs with regard to sterilization of milk. 



The intertransmissibility of human and bovine tuberculosis, R. R. Din- 

 wiDDiE {Jour. Amer. Med. Assoc, 39 {1902), No. 2.i, pp. 157-}- Jo77).— The author 

 discusses the anatomical lesions in cases of bovine tuberculosis and devotes special 

 attention to an account of experiments which have been made to determine the 

 conq)arative virulence of bovine tubercle bacilli for different species of animals. 

 During the author's tirst experiments he was inclined to the belief that the bovine 

 tubercle bacilli exercised a sort of selection among different animals, but later experi- 

 ments indicate that this organism possesses an indiscriminate excess of virulence 

 over the human tul)erc]e Imcillus. 



Sanitary measures for the prevention of tuberculosis in Nevr York City and 

 their results, H. ]M. Biggs {Jour. Amer. Med. Assoc, 39 {1902), No. 26, pp. 1635- 

 1640). — The origin of tuberculosis in human patients and the means of transmission 

 of this disease from man to man and from tuberculous animal products to man are 

 discussed. Attention is called to the slow development of tuberculosis and the con- 

 sequent ditiiculties in determining the source of infection. The author urges the 

 desirability of exercising special precautions in preventing the transmission of this 

 disease by whatever agency. 



Transmission of bovine tuberculosis to man by accidental inoculation, and 

 the experimental reinoculation of calves, Sproxck and HoEFNACiEL {^iiin. Med. 

 TV/., 51 {1902), No. 11, })p. 589-599). — A detailed account is given of a case in which 

 the authors believe that bovine tuberculosis was transmitted to man through a skin 

 wound. The Avound was on the finger and the apparent results of infection were 

 seen in swelling of the arm and inflammation of some of the lymphatic glands. 

 Material taken from the finger, which was amputated in treating the case, was used 

 in inoculating guinea pigs, in which tuberculosis developed after the usual incuba- 

 tion period. The organism was then passed a second time through a guinea pig and 

 virus obtained from the second guinea pig was used in inoculating a heifer, which 

 rapidly developed signs of tuberculous infection. 



Tubercular peritonitis in early life, T. M. Rotch {.Jour. Amer. Med. A^soc,.40 

 {1903), No. 2, pp. 69-73). — Notes are given on the clinical symptoms, diagnosis, and 

 pathological anatomy of tubercular peritonitis in children, with regard to its rela- 

 tionship to bovine tuberculosis. The mesenteric lymph glands may often be affected 

 as well as the alimentary tract, lungs, and other organs. The region of the infection 

 in such cases is frequently doubtful. 



Ohio combating tuberculosis, J. C. Burneson {Ayner. Vet. Rer., 26 {1902), No. 

 4, pp. 328-333) . — Notes are given on the methods adopted in inspecting cattle in
