VETERINARY SCIENCE AND PRACTICE. 87 



A critical examination of the position of Dr. Koch on the subject of human 

 tuberculosis, 8. Ahloino [Jour. Med. \'it. el Zootech., .5. ser., 5 [1901), Oct., pp. 

 577-593). — This article is controversial in nature and the author seeks to array the 

 many arguments which lead to conclusions contradictory to that of Koch. A report 

 is made on experiments showini; that goats, nmles, cattle, and rabbits may be infected 

 with tubercle bacilli of human origin. It is argued that the virulence of tubercle 

 bacilli may vary to a consideral)le extent under different conditions and that this 

 variation of virulence in different animals does not necessarily indicate different 

 s})ecies of bac^teria, but merely variations of the same species under different conditions 

 of growth and development. 



Report of the tuberculosis commission, C. H. Cook {New Jersey State Bd. Arjr. 

 Rpt. 1901, pp. 223-2&3). — The tuberculosis commission has continued to make exami- 

 nation of dairy cows which constitute the dairy herds within the State. Such 

 examination was made in all cases where application has been made according to law 

 so far as the appropriation permitted. During the year 1901 the total mnnber of 

 applications for examination was 190; the nuud)er of animals comprised in these 

 herds, ^,512; and the number condenine<l, ;>42. The total indenmity i)aid for animals 

 destroyed was $7,2ti0.75. The tul)erculin test has also been made upon all cattle 

 importetl from other States. 



Serum diagnosis in tuberculosis, <«. Cakriere {Compt. Bend. ,Soc. Biol. Paris, 

 53 {1901), No. 25, pp. 74'>, 747). — From numerous observations made by the author 

 it is believed that this method is subject to some practical difficulties and requires 

 special training for its application. It is an extremely sensitive method and gives 

 the same results in young and ol<l patients. 



On the subject of sensibilizing substances in the serum of tuberculous 

 patients, J. Camus and P. Pagniez {Compt. Bend. Soc. Biol. J'ari.'^, 53 {1901), No. 

 25, pp. 734, 735). — In samples of serum obtained from tuberculous patients the pres- 

 ence of a sensibilizing substance causing, to some extent, the disapi)earance of alexin 

 was determined. This phenomenon was not observed in every instance, but it is 

 believed to be of general occurrence. 



Tuberculin as a diagnostic of tuberculosis in cattle, J. Smith {Trans. High- 

 land and Agr. Soc. Scotland, 5. ser., 14 {1902), pp. 166-171). — On account of the 

 number of failures of a reaction from tuberi'ulin in cattle which were suljsecjuently 

 found to l)e tuberculous, further investigation of the subject was made by J. M. 

 Young, who presents a report on 42 cattle which were tested with tuljerculin. Of 

 the 42 cows which were tested, 21 were found after slaughtering to be tu])erculous, 

 and of these only 17 had reacted to the test. It is reconnnended that in using the 

 tuberculin test the temperature should ))e taken at least 4 times after inoculation, 

 viz, at 9, 12, 15, and 18 hours after injection. In cases where the temperature 

 appears to be gradually rismg at the last period, it is recommended that it be taken 

 subsequently, 21 hours after the inoculation. 



The tubercle bacillus in feces, D. Anglade {Compt. Rend. Soc. Biol. Paris, 53 

 {1901), No. 2S, pp. 829, 830). — According to observations by the author tubercle 

 bacillus is almost always found in the feces, in cases where the intestines are involved 

 in the progress of tuberculosis. Brief notes are given on a means of identitication of 

 tubercle bacillus in feces. These observations are considered of importance from a 

 sanitary standpoint. 



Lecithin in tuberculosis, H. Claude and A. Zaky {Compt. Bend. Soc. Biol. 

 Paris, 53 {1901), No. 28, pp. 821-823). — Experiments with tuberculous guinea pigs 

 and man showed that the use of lecithin does not directly check the development of 

 tuberculosis, but that it modifies the nutritive processes favorably; under its influ- 

 ence the weight of the body increases, metabolic processes become more active, and 

 the elimination of phosphorus is considerably diminished.
