84 EXPERIMENT STATION RECOED. 



in the struggle of the infected organism against tubercle bacilli neither the com- 

 plement nor phagocytosis clue to polynuclear and mononuclear cells exercises a 

 decisive role. The phagocytosis which appears in a striking manner is largely 

 due to the action of leucocytes found in the lymphatic ghinds or in other places 

 where lymphocyte cells collect in large numl)ers. 



A special method for cultivating tubercle bacillus on potatoes, J. Anzi- 

 LOTTi {VcjtthJ. Bukt. [etc.]. 1. Aht., Ori;/.. 'lO (lOIK!). Xo. -Kjjp. 77).7-76*,S).— By a 

 combination of potatoes and glyrerin. the author found it possible to bring 

 about a more rapid and luxuriant growth of tubercle bac-illi than by any other 

 method with which he had experimented. The bacilli tlius obtained appeared 

 to remain in an active and virulent condition for long periods, and the virulence 

 of the cultures was in many cases greatly increased. 



The tubercle bacillus cultivated in a saccharine medium, L. Vailliant 

 (Compt. Rend. Hoc. Biol. \l>(iiix\. GO {1!)06), Xo. ].'>. p/). 7'//-77/.:?).— The author 

 ;idded saccharose and glucose to a bouillon medium for the purpose of testing 

 these substances. It appears from these experiments that saccharose and 

 glucose exercise an effect on the amount of chloroform-bacilline produced by 

 the tubercle bacillus. 



A method for demonstrating anthrax bacilli in blood and tissues, 

 J. FORSTER {Cciithl. Bitht. \c1(:\. 1. Aht.. Ori;/.. -'/O (HXIH). Xo. ■'>. pp. 7.')]-7.'j-',) . — 

 A simple metliod for demonstrating anthrax bacilli has been found in the use of 

 gypsum. After allowing the suspected material to grow for some time on a 

 gypsum rod, cultures are made from this material in order to subject them to 

 microscopic examination. If such cultures are heated to a temperature of 

 65° C. for 2 minutes, other bacteria such as coli bacillus and proteus will be 

 killed, while the anthrax bacilli will lie luiaffected. 



Protozoan blood diseases of man and animals in German East Africa, 

 A. Treutlein (.y a lichen. Med. Wc]iiif<c]ir.. .'>.i ilHiiC), Xo. 18, pp. S'io-S.jT). — 

 Brief notes are given on the classification of the protozoa which are concerned 

 in the production of blood diseases in man and animals. It was observed dur- 

 ing investigations made in the region of Dares-Salaam that organisms resem- 

 bling trypanosomes were freiiuently seen in blood preparations in cattle suffer- 

 ing from Texas fever or African coast fever. 



Ticks and African coast fever, C. P. Lounsbury {Af/r. .Jour. (Uipc Good 

 Hope, 28 (1906), Xo. J, pp. ().3J/-6o.'f). — The investigations of the author regard- 

 ing the means of transmission of African coast fever have been continued. At 

 first it was believed that only two species of ticks were concerned in transmit- 

 ting this disease. It has been found, however, that 5 species are implicated — 

 Uliipieephahis oppeudieHhituK. R. evcrtsi, R. siiinis, R. iiiteii.'<. and A*, capeiisis. 

 Otiier ticks belonging to different genera apparently have nothing to do in 

 transmitting African coast fever. In the author's experiments it was found 

 jHtssible to triUismit the disease by means of one infected tick, but usually more 

 were required. The incubation period averaged 13J days and the duration of 

 the disease 12 days. As a rule, the animals did not show serious symptoms 

 until within a few days before death. Often it is impossible to transmit the 

 Infection by means of the ticks from diseased animals. In 35 cases positive 

 results were obtained, and in all these cases the ticks had become infected in 

 one stage of growth and communicated the disease in the succeeding stage. 



Tissue alterations in the cows' udder in cases of sporadic galactophoritis. 

 Van der Linde (Arch. IF/.v.v. ». Prakt. Tierlieilk., 32 (1906), Xo. J,-5, pp. 3.31-362, 

 pis. 2). — Detailed clinical notes are given on 35 cases of this disease. As a 

 result of these studies the .•lutiior comes to the conclusion that the udder of the 

 cow exhibits a tubular chai'acter just before the jjeriod of lactation, while
