The epizootic diarrhea of calves and meat poisoning, W Fally (Iter. 

 Crii. M('(l. \ rl.. II (I'.IOH), So. l.iO, pp. .•j7.5-.5.SJ ) .— The author has studied the 

 micro-or.irauisms to determine the relations existing between epizootic diarrhea, 

 a wide-spread affection of young cattle, and the poisoning that has frequently 

 been observed to follow the consumption of veal. Calves affected with the 

 disease were killed in extremis at the Brussels abattoir and the bacilli studied. 

 When their cultural characters and agglutinin reactions were comiiared with 

 those of the meat jioisoning bacilli a close i-esemblance was found, it being 

 imi)0Ssible to distinguish the i)aracoloH li.icilli encountered in the calves from 

 those belonging to the tirst enlei-itidis subgroup. 



The dehorning' of cattle. K. W. IIk kman {TJ. /S. Dcpt. Agr., Bur. Aiiini. 

 /itdiis. Rpt. JU07, pp. 2'.n-.U)G. /if/s. li ; l'(tnii<rx' Jiul. 3.')0. pp. I), fif/s. (it. — The 

 author here furnishes directions for the guidance of the dairy farmer or other 

 cattle owner in the dehorning of cattle. Methods of dehorning as practiced on 

 the range are briefly described, as is also the prevention of horn growth in 

 youug calves. 



The inoculation of sheep against blue tongue and the results in practice, 

 A Theileb (Transvaal Agr. Jour., 7 (7.908), No. 25, pp. 30-39).— A report of the 

 results of Inoculation with viitis obtained after the eleventh generation from 

 sheep, a brief report of which has been previously noted (E. S. K., 20, p. 679). 

 Tietween September. 1007, and February, lOOS. over 00.000 doses of this vaccine 

 were distributed in the Transvaal and over 100.000 doses among the other South 

 African colonies. The absence of heavy rain during the season apjteared to 

 corroborate the theory that the carrier of the blue tongue micro-orgauism is 

 a biting insect which requires water for its development. Detailed directions 

 are given for the use of the vaccine, which has ])roved eminently successful. 



Tuberculosis of hogs: Its cause and suppression, J. R. Mohler and H. J.

Embryonal adenosarcoma of the kidney in swine, Ij. E. D.\y (U. S. Dcpt. 

 Agr.. Bur. Anim. Indus. Rpt. 1907. pp. 2J,7-257. figs. 8).— The author reports 

 the discovery of these neoplasms during the course of meat inspection work. 

 They are said to usually escape notice until the post-mortem examination is 

 made. " They appear as a large, encapsulated, iri-egular mass in the sublumbar 

 region, extending perhaps from the diaphragm to the border of the pelvic 

 cavity. T'sually only one kidney is involved, but in some cases both are affected. 

 When but one kidney is involved there is no predilection as to the side, the 

 left kidney being affected as often as the right, and vice versa. These growths 

 are comparatively rare and occur only in young hogs up to 18 months old. 

 They grow very rapidly and may become very large. Recently one of these 

 tumors weighing GO lbs. was observed by the writer in a Chicago abattoir. 



"The writer has never found such neoplasms in cattle or sheep and has no 

 information that they have been observed in those animals by others." 



The results of a histological study of these tumors are presented.
