and meat dealert^. Details are given concerning the history of a few of these cases. 

 While among the patients which were examined by the author less than 0.03 per 

 cent were affected with cutaneous tuberculosis, this is believed nevertheless to indi- 

 cate the comparatively serious danger from infection by l)ovine tuberculosis in skin 

 wounds. 



Pearl disease and human tuberculosis, .M. Wolff {Dfut. Med. Wdmschr., :^S 

 {1902), No. 32, pp. 566-570). — Tliis artick' is (if a controversial nature. The author 

 argues from the results of experiments and from ol)servations that bovine tubercu- 

 losis may l)e transmitted to man. Detaile<l notes are given on a case of pi-imary 

 alimentary tul)erculosis of man which can only be explained as the result of infection 

 from tuberculous animal products. A number of experiments were made in inocu- 

 lating animals with material obtained from this and other cases. As a result of these 

 inoculations and post-mortem examinations it is argued that tuberculosis may a[)iiear 

 in man and cattle under the same form, and that the 2 diseases are identical. It is 

 urged, therefore, that all measures which have been ado|)ted for preventing the 

 spread of tuberculosis by means of animal products should l)e rigidly adhered to. 



"What is pearl disease? J. Orth {Berlin. Klin. Wclim^chr., S9 {1902), No. 34, pp. 

 793-79S). — Brief notes are given on the different views which have been held regard- 

 ing the nature of jjearl disease and its relationship to human tuberculosis. A num- 

 ber of experiments were conducted in which experimental animals were inoculated 

 with tuberculous material of human origin and the material obtained from these 

 animals was then used in testing the susceptibility of calves, hogs, and goats. Three 

 of each of these animals were used in the experiments. Among the calves, 2 showed 

 only local changes while 1 exhibited considerable evidence of generalized tubercu- 

 losis, including swelling of the mesenteric, portal, and cardiac lymjihatic glands. 

 Similar results were obtained with the hogs, of which 2 were only slightly infected, 

 while 1 exhibited considerable tuberculous alterations. All three of the goats became 

 affected with generalized tuberculosis. The author concludes, therefore, that tuber- 

 cle bacilli of human origin may l)e so increased in virulence as to become pathogenic 

 for domesticated animals. 



Tuberculosis of the transversely striated muscles, 8. Saltykow ( Centhl. 

 AUg. Path. v. Path. Anat., 1.-, {1902), No. 18, pp. 715-718).— X brief review is given 

 of the literature relating to the suV)ject of the l>ehavior of tlie musculature toward 

 infection with tuberculosis. The author made a number of experimeiats on rabbits. 

 The animals were inoculated intravenously with tubercle baccilli and the tu]:)ercles 

 which developed as a result of this infection were carefully studied with regard to 

 histological details. The muscles were examined at various periods ranging from 2 

 to 25 days after the inoculation. Detailed notes are given on the histological features 

 and changes observed in the muscles. The tubercles appeared to arise first in the 

 walls of the blood vessels, and were at first formed by the cells of these walls. Later, 

 muscle and other tissues seemed to T)e concerned in the formation of the tubercles. 

 It was not until 12 days after inoculation that any proliferation of muscle cells 

 could be observed in the neighborhood of the forming tubercles. 



Combating' bovine tuberculosis in Norway, O. Malm {Tidssh-. Nori^ke Landhr., 

 9 {1902), No. 10, pp. 4.55-467). — An appropriation was made for the study of the 

 <liagnostic value of tuberculin in 1891, and in 1895 systematic work on the prol)lem 

 of bovine tuberculosis in Norway was begun. Extensive tuberculin tests were made 

 between this date and 1901 and the results of these tests were summarized. It was 

 found that the number of infected animals varied from 3.3 to 8.4 i)er cent. The 

 smallest infestation was found in younger animals, while the more extensive infesta- 

 tion was observed in animals 5 years or more old. It is believed that a successful 

 fight can be Avaged against the bovine tuberculosis in Norway by means of thorough 

 tuberculin tests and through the cooperation of veterinarians, progressive stock 

 farmers, and officials. — f. w. woll.
