roumU'd by leucocytes and cai-ried by these corpuscles into various i)arts fit the 

 body. The author believes that nearly all internal localizations of tuberculous 

 infection are of intestinal origin. 



Resorption of dead tubercle bacilli, A. Marmokkk (HcrVni. Klin. Wchnschr., 

 .'i3 {1!J()6), Ao. 36, pp. 1119. ii8f>).— Different samples of cultures were sub- 

 jected to temperatures ranging from 100 to 120° C. for periods of 1 to 60 

 minutes, and experiments carried out on guinea pigs and rabbits with rela- 

 tively large quantities of dead tubercle bacilli showed conclusively that these 

 bacilli may be absorbed by the experimental animals without the production of 

 an abscess at the point of inoculation. 



In order to secure a resorption of the dead tubercle bacilli without the for- 

 mation of an abscess it is necessary to carefully pulverize the material before 

 making an injection, as if relatively large masses of dead tubercle cultures are 

 deposited under the skin in experimental animals an abscess is sure to follow. 



In general it is found that rabbits i)ossess a much more striking power of 

 absorbing the bodies of tubercle bacilli than guinea pigs, and therefore will 

 endure a large quantity of tubercle bacilli without showing the develo])ment of 

 extensive inflannnation or abscesses. 



The action of bovine and human tubercle bacilli upon anthropoid apes, 

 E. voN DuNGERN and H. Schmidt (Arh. K. Gsndhtmmt.. 23 {1906). A'o. 2. pp. 

 510-581). — A series of inoculation experiments was carried out upon anthropoid 

 apes, during which tubercle bacilli of human and bovine origin were used. 



It appeared that the bovine bacilli were fully as virulent for the gibbon as 

 human tubercle bacilli. Since the gibbon is considered as very closely related 

 to man, it is argued that the results obtained may be looked upon as applicable 

 also to man. Further experiments \Aill be made along this line. When human 

 tubercle bacilli were fed to gibbons, tuberculous foci appeared in the lungs, 

 while after feeding bovine bacilli the alimentary tract and mesenteric glands 

 were chiefly affected. 



Protective vaccination against Texas fever, Graffunder (Bniiii. Tieriirztl. 

 Wchnschr., 1906, Ao. 36, pp. 656-659). — As a result of the study of this disease in 

 Germany, the author concludes that a comi^lete innnunity can not be produced by 

 1 or 2 vaccinations. 



It is recommended that the vaccination l>e done on calves from weeks to 1 

 year old and preferably during the winter. The si/e of the vaccine dose varies 

 from 5 to 1." cc. 



Piroplasnia bigeniinuni in Texas fever in Lolland, A. F. Folcer (Mdinicil- 

 skr. Djjrlo'i/cr. IS (1906), No. 5, pp. 230-235, pfi. 1). — Historical references are 

 made to the literature of this subject with particular reference to the biology of 

 the blood i)arasite and the use of hemoglobin in treating the disease. 



Redwater in cattle, G. H. Wooldridge (Agr. t'^tttdcnts' Gaz., n. ser., 13 

 {1906), No. 1, pp. 2-12, pis. S). — The author describes in some detail the symp- 

 toms and post-mortem appearances which may be observed in acute and chronic 

 cases of Texas fever. The means of transmission as well as curative and pre- 

 ventive treatments are also discussed. 



The cattle tick in its relation to southern agriculture, A. Mayer iV. aS'. 

 Dept. Agr. Farmers' Btil. 261, pp. 22). — In the author's opinion the chief diffi- 

 culty in the way of improving the cattle industry of the South is the presence of 

 the cattle tick. It is recognized that the cattle tick on the range country is by 

 no means so serious as on improved pastures in which the infestation has become 

 continually woi^se. 



Attention is called to the injury to cattle from parasitism with ticks. Aside 

 from the agency of these pests in transmitting Texas fever, beef cattle badly
