 Attention is called to the importance of meat and milk as human food and to the 

 possible dangers to human health from the consumption of tul)erculous products. 

 Brief notes are given on the classification of meat in abattoirs according to its 

 hygienic condition. The author believes that, as a result of tiiese studies and experi- 

 ments, tuberculosis of man and cattle are 2 forms of the same disease. Brief notes 

 ari^ also given on the distribution and statistics of tu])erculosis. 



The Public Health (Scotland) Act, 1897, and its relation to owners of stock, 

 J. llic.NDiCKSOX ( Tr(in><. Iliglildml itud A(jr. Sac. Scotlmid, .7. .vcr., 15 {1,903), jip. 63-6!)). — 

 Attention is called to the provisions of this law which relate to the sale of diseased 

 animals and meat products. It is argued that in many instances the stoc-k raiser 

 may be unable to recognize the symptoms of disease and is not therefore criminally 

 responsible for selling such animals for meat. 



Cerebral tuberculosis, G. Nuvoletti {Gior. li. ^'o^. ^[rcdd. \'<i. JloL, 51 {1902), 

 No. 37, pp. 921-924). — The g,uthor describes the gross and microscoi)ic features of 

 tubercles obtained from the surface of the brain in cases of bovine tuberculosis. 



Extracts of tubercle bacilli and other tuberculins other than those of Koch, 

 L. (IriXAKD (7u7'. Tithi'rciiJo.sc, 9 (1902), Xo. 3, pp. ;.W>-5/.'y) .—Tlie author gives a 

 detailed description of the methods used in obtaining extracts of tul)ercle bacilli and 

 producing tuberculin as ])ract'ceii by Hunter, Cheyne, Klebs, Hirschfelder, Weyl, 

 Denvs, Vesely, de Schwemitz. ^laragliano, von Behring, Arloing, (Juinard, and

Variations in the virulence of different cultured of turbercle bacilli, D. 

 Vkszpremi {Centbl. Bali. n. Par., I Aid., 33 {1903), .Vo.s'. ,5, Orlg., pp. 176-184; 4, PP- 

 255-259). — The purpose of the investigations reported in the present paper was to 

 determine whether there is in general a variation in the virulence of different cul- 

 tures of tubercle l)acilli corresponding to the differences in malignity of various cases 

 of tul)erculosis among human beings. 



In these experiments 8 cultures were used from diiferent human cases of tu))ercu- 

 losis; and from each culture material was taken for inoculation of 2 or more rabbits 

 in the auricular vein. The amount of material used was about 3 mg. for each rab- 

 bit. Details are given concerning the effects of these different cultures on the 

 experimental animals. It was found that tubercle bacilli in pure cultures when 

 injected in suitable quantities into animal organisms may produce toxins which 

 operate unfavorably upon experimental animals. These toxins arc of considerable 

 influence upon the severity of the infection. It was found also during these experi- 

 ments that tubercle bacilli may indicate spontaneous degeneration and that artificial 

 cases of tuberculosis may finally result in recovery. The tul)ercle l)acilli in fresh 

 cultures from different cases of human tuberculosis, especially of the ])ulmonary 

 form, showed decided differences in virulence. Cultures of tubercle bacnlli kept for 

 a considerable period upon artificial mitrient media were gra(Uially attenuated or 

 completely lost their virulence. 



It is believed as a result of these experiments that tubercle bacilli from different 

 cases of this disease possess essentially different degrees of virulence, which may 

 account in part for the observed differences in virulence and rapidity of extension in 

 different cases of tuberculosis. 



Treatment of parturient paresis with iodid of potash, L. Misier (AVc. Med. 

 Vcl., S. ser., 9 {1902), No. 11, pp. 342-345).— Ex ceWent results were ol)tained from 

 the use of hypodermic and intramammary injections with iodid of potash. After 

 the administration of this chemical the author recommends the use of a hypodermic 

 injection containing benzoate of eserin and sulphate of veratrin in water.
