In order to gain information regarding the toxic properties of lysoform the author 

 conducted experiments on rabbits, dogs, cats, horses, cattle, sheep, and chickens. 

 In these investigations the subcutaneous, intravenous, and intraperitoneal methods 

 were avoided. Lysoform was given by way of the mouth. As a result of the 

 author's exp iriments it is concluded that lysoform is the least poisonous of the ordi- 

 nary disinfectants. It appears to satisfy the ordinary veterinary requirements for an 

 antiseptic Bubstance, and is more effective as a <1 lorizer than the majorit} of simi- 

 lar disinfectants. Lvsoform appears to be particularly adapted for use in veterinary 

 obstetric practice and in the treatment of weak animals.

During the experiments reported in the paper various races of tubercle bacilli of 

 different origin were utilized and inoculation experiments were made with various 

 laboratory animals. Detailed notes are given on the technique of the author-' experi- 

 ments. As a result of the authors' investigations it appear- thai in general the mul- 

 tiplication of tubercle bacilli post-mortem in tissues specifically altered by the bacilli 

 probably takes place in the absence of other micro-organisms and under favorable 

 temp, rature conditions, although this is not a matter of certainty. 



It was possible to observe various morphological alteration- in tin- tubercle bacilli, 

 Buch as segmentation, granular disintegration, branching, and other changes of form. 

 Dead tubercle bacilli which wore low in virulence when encapsulated in organs spe- 

 cifically affected by the bacilli are not able to cause specific alterations or general 

 infection in inoculated animals. 



Immunization of cattle against tuberculosis and serum experiments with 

 this disease, Libbertz and Ruppel ( Deut. Med. Wchnschr., 11 (1005), Nos. 4, />/>■ 189- 

 /.;/; 5, pp. 182-184)- — A test was made of a method of immunization recommended 

 by Friedmann in using tubercle bacilli obtained from turtles. During these ex] 

 ments the authors treated •"> cattle with tubercle bacilli from turtles and subsequently 

 examined the serum of the treated animals. 



As a resull of the test tin- authors conclude that Friedmann' s cultures are not with- 

 out danger for warm-blooded animals. It appears that they produce serious intoxi- 

 cation ami organic changes which may cause death without the development of true 

 tuberculosis. Intravenous injections of Friedmanu's culture- are not capable of pro- 

 tecting warm-bl led animals from later infection with tuberculosis. The injections 



of these cultures do not produce immune bodies in warm-blooded animals. 



Immunization against tuberculosis by means of tubercle bacilli from tur- 

 tles, F. Y. Friedmann {Devt. Med. Wchnschr., 81 [1905), No. 5, pp. 184-186) .— This 

 article is of a controversial nature and was written in reply to a criticism by Libbertz 

 and Ruppel. 



According to the author's experiments, guinea pigs may be successfully immunized 

 against tuberculosis by previous treatment with tubercle bacilli from turtles. The 

 control animals died within 3 weeks of generalised tuberculosis, while immunized 

 animal- were found to be quite free from the disease when killed and examined 70 

 days after inoculation. It is denied that the cultures of tuheivle bacilli from turtles 

 exercise any pronounced harmful action upon cattle. ( attic treated with such cul- 

 tures acquire a rather pronounced immunity, which can be further intensified by 

 inoculation with bovine tubercle bacilli.
