776 EXPERIMENT STATION RECORD. 



Primary tuberculosis of the larynx, H. Holterbach {Deut. Tierdrzil. 

 Wchnschr., i-J {1906), No. J,Ji, pp. 541, 5Ji2). — Tuberculosis of the larynx in the 

 primary form is not of common occurrence. On this account the author de- 

 scribes in detail an undoubted case in a cow resulting in death after 1 year and 

 causing a complete loss of voice, which persisted for 10 months before death. 

 The tuberculous infection in the region of the larynx was of an' acute and 

 rapidly extending nature, but there were no lesions in the lungs or even in 

 the lymph glands in the region of the larynx. 



Immobility in cattle as a result of tuberculosis, E. Bisnoit (Rec. Yet. 

 [Toiiloii.sc]. 31 [li)O(l). A'o. 11. pii. 101-710). — Considerable attention has been 

 given by the author to cases of tuberculosis affecting the brain and causing 

 some form of meningitis which results in a loss of the power of motion on the 

 part of the affected animal. In the cases which have come under his obser- 

 vation there were tuberculous lesions in the lungs and other organs and the 

 cerebral symptoms were so pronounced as to indicate serious lesions in the 

 l)rain. 



Cases of apparent recovery from experimental tuberculosis, L. Martin 

 and A. Vaudre.mer (Vompt. Rend. tSoc. Biol. [Paris], 61 {1906), No. 28, pp. 

 260-262). — As a result of treatment with tubercle bacilli from which the fatty 

 substances had been removed, apparent recoveries took place in rabbits, but in 

 some cases the tubercles wliich apparently had healed subsequently showed 

 virulence. The authors, therefore, recommend caution in experiments of this 

 sort to avoid mistakes of judgment after the use of tubercle bacilli of low 

 virulence. 



The actual status of vaccination and serotherapy for tuberculosis, G. 

 Moussu {Rec. Med. Fdt, 83 {1906), No. 21, pp. 741-758).— In this article the 

 position is taken that the views commonly expressed regarding the present 

 methods of serotherapy for tuberculosis are nmch too optimistic. The author 

 expresses the o])inion that a relinl)le method of treatment is still to be found. 



Quantitative relations of agglutination of tubercle bacilli, L. Karwacki 

 and W. Benni {Ceutbl. Bald, [etc.], l.AU., Orig., 42 {1906), Nos. 3, pp. 252-254; 

 4, pp. 345-348). — The agglutinating power of tuberculous sera for tubercle 

 bacilli is much less than in the case of such diseases as typhoid and cholera. 

 In general the absorption coefficient diminishes as the concentration of the serum 

 increases. The agglutinins were apparently destroyed by heating the serum to 

 a temperature of 100° C. diluted in 3 parts of water to which 3 per cent of 

 glycerin had been added. 



Abdominal zoogleic tuberculosis of birds, J. Roger {Rev. Vet. [Toulovse], 

 31 {1906). No. 12, pp. 761.762). — Quite frequently, supposed cases of tuberculosis 

 of tlie internal organs of fowls prove to be due to mites or some other organ- 

 ism than the tubercle bacillus. In most cases of true tuberculosis of fowls, the 

 spleen is affected and the liver is almost invariably attacked. 



Experinaents with fish tubercle bacilli cultivated at a temperature of 37° C, 

 A. AuJESZKY {Ceiithl. Bakt. [vtc]. 1. AM.. Orhj., i^ {1906), No. 5, pp. 

 397-401). — Considerable difficulty has been experienced in getting tubercle 

 bacilli from fish to live at a blood temperature. The author began with a 

 medium containing potatoes and glycerin water at a temperature of 28 to 30° C. 

 and after 6 weeks, or at the end of the fifth generation, the temperature was 

 increased to 37° C. In the meantime the cultures had ceased to be white and 

 glistening, as is the case with ordinary tubercle bacilli from fish, and had 

 assumed a yellowish-gray color resembling that of the ordinary maunnalian 

 tubercle bacilli. 



These bacilli after cultivaticm on the media maintained at a temperature of
