injections of the fluid obtained by filtering tuberculous material conferred a more 

 T)ronounced chenaotactic action upon the serum of experimental goats, rendering it 

 more decidedly antituberculous. 



Contagion and tuberculosis in man and beast, G. F. Keene {Rhode Island 

 State Bd. Agr. Rpt. 1901, pp. 8S-9S). —Thii^ article is of a controversial nature and 

 contains a brief summary of evidence which indicates the possibility of transmission 

 of tuberculosis from animals to man. 



Further contribution to the possibility of transmission of tuberculosis 

 from man to hogs, M. Tempel {Ztschr. Fleisrh u. Milrhhijg., 12 {1902), No. 8, pp. 231, 

 ^,5;_>)._The author had previously suspected the possibility of transmission of tuber- 

 culosis from tuberculous attendants to hogs. A number of cases of tuberculosis in 

 hogs have been observed in which the disease appeared to have gained entrance 

 through the wound in the scrotum in consequence of the operation of emasculation. 

 Further observation on this point indicated that such cases are rather frequent. In 

 one instance 4 hogs were apparently infected in that manner by an operator who was 

 suffering from tuberculosis of the larynx and who had the habit of holding his knife^ 

 between his teeth. 



Is tuberculosis hereditary? A. van Leeuwen ( Tijdschr. Veeartsenijk. Maanblady 

 29 {1902), No. 5, pp. 197-201). — This article is of a controversial nature, and in it the 

 author makes the assertion that even if tuberculosis is not strictly hereditary, it may 

 nevertheless be congenital or may take its origin during the development of the fetus. 

 It is also argued that evidence exists for the assumption of predisposition to tubercu- 

 losis in the offspring of tuberculous animals. 



The tuberculin test for tuberculosis, D. E. Salmon ( U. S. Dept. Agr. Yearbook 

 1901, pp. 581-592) . — The author presents a brief review of the opinions of various 

 European and American investigators as to the efficacy and effect of the tuberculin 

 test. It is concluded that the test is exceedingly accurate, that by its use tuberculosis 

 in its incipient stage may be detected, and that no injurious effects are produced by 

 tuberculin in healthy cattle. 



A report on the proceedings of the British Congress on Tuberculosis, held 

 in London, July, 1901, M. P. Ravenel {Fenmylvanm DepA. Agr. Bpt. 1901, pt. 1, 

 pp. 447-488) . 



Diagnosis of anthrax, J. BoNtiEKT {Ztschr. Fleisch u. Milchhyg., 12 {1902), No. 7, 

 pp. 193-202, Jigs. 8) . — The objects of the experiments reported in this paper were to 

 determine how long after death the anthrax bacillus could be demonstrated in mate- 

 rial from the dead body by one or another of the staining methods of Johne, Klett, 

 and Olt, and also to determine the best and surest method for identifying the anthrax 

 bacillus in such material. During these experiments it was found that the demon- 

 stration of anthrax bacilli by streak cultures frequently failed. The causes of these 

 failures were found in the changes in form that the anthrax bacillus undergoes in 

 consequence of the action of putrefactive bacteria and in the fact that anthrax bacilli 

 are frequently not present in the blood in sufficient numbers to enable their ready 

 identification by streak cultures. As a result of the experiments the author concludes 

 that the morphological demonstration of anthrax bacillus in streak culture does not 

 offer a certain means of determining whether a given animal died of anthrax or not.' 

 The best and most certain method of bacteriological diagnosis of anthrax is found in 

 plate cultures. The most suitable method for pi-eserving anthrax material which is 

 to be studied later or shipped some distance is by slow drying of the virulent matter 

 in a thick layer upon glass slides or on the inside of glass tubes. 



The disinfection of animal hair by means of steam, Proskauer and Conraui 

 {Ztschr. Ilgg. u. htfertionskrank., 40 {1901), No. 1, pp. 134-140). — Experiments were 

 made for the inirposeof determining the effectiveness of different methods in killing 

 anthrax spores on animal hair. Three forms of steam sterilizing apparatus were 

 used, and it was found impossible to obtain the same results by the 3 forms of appa-
