the pillars of the dlapliragm. One piece only should be taken from each pig. 

 Twenty-four preparations the size of an oat grain should be examined from 

 each piece taken. The piece of tissue removed should always contain tendon 

 tissue. If trichinae are found, fresh pieces should be taken for control exami- 

 nations." 



Cause and treatment of pulmonary emphysema, W. G. Hollingwobth 

 {Amer. Vet.. Rev., JfO (1911), No. 2, pp. 223-228).— This is a discussion in 

 regard to the supposed etiological factors of the various forms of this condi- 

 tion and the curative, or palliative treatment. A discussion is also included in 

 regard to the setting aside of a contract or sale on the basis of diagnosing the 

 presence of broken wind in horses. 



Administration of Salvarsan for the treatment of contagious pleuro- 

 pneumonia in horses, Rips (Berlin. Tierdrztl. Wchnschr., 21 (1911), No. IS, 

 pp. 321-323).— A description of the methods and the precautions to be taken 

 while administering Salvarsan for the treatment of the pectoral form of 

 equine influenza. 



The trypanosomes found in two horses naturally infected in the Gambia, 

 W. YoRKE and B. Blacklock (Ann. Trap. Med. and Par., 5 (1911), No. 3, pp. 

 4IS-43I1, pi. 1). — The trypanosome found in one of the horses is thought to 

 have been Trypanosoma dimorphon. A long form found in the other horse ap- 

 peared to be T. vivax, but a short form was not assigned a position. It is 

 thought that it may have been either a dimorphon-like trypanosome of low 

 pathogenicity or simply a modification of the long parasite. 



The distribution of Piroplasma canis in infected dogs that have been 

 treated with arsenic preparations, E. Goldschmid (Ztschr. Immunitdtsf. u. 

 Expt. Ther., I, Orig., 5 (1910), No. 6, pp. 663-6S8, pi. i).— This work reports 

 investigations of the patho-anatomical changes in dogs infected with a Russian 

 virus of P. canis which in part were treated with arsenic preparations. 



Contributions to the pathological anatomy of fowl cholera, O. Preuss 

 (Beitrag sur Pathologischeii Anaiomie dcr Gcflilgclcholcra. Inaiig. Diss., 

 Univ. Bern, 1909, pp. 63). — The material for this work was obtained from an 

 enzootic which involved the death of 30 chickens. All animals came to autopsy. 



It is concluded from this investigation that the pathological changes in the 

 air sacs and other serous membranes of birds succumbing to fowl cholera are 

 not constant ones, and therefore can not serve as a criterion for determining 

 the length of time the disease is present or fixing the extent of the infection. 

 The small grayish white to grayish yellow caseous foci in the liver were pres- 

 ent in acute, subacute, and chronic cases. Their presence indicates infection 

 with small amounts of fowl cholera bacteria. The receptivity of animals for 

 the fowl cholera bacteria and the development of the pathological processes 

 are not characteristic of a few types or species of birds, but vary among the 

 individuals themselves. Guinea pigs and mice which were infected with this 

 bacterium do not show any particular changes in the organs. The intestinal 

 tract is the chief area infected. 



Pellagrous symptoms produced experimentally in fowls by feeding maize 

 spoiled by inoculation with a specific bacterium, C. C Bass (Jour. Amer. 

 Med. Assoc, 57 (1911), No. 21, pp. 1681,, 1685, figs. 2).— The author, for a series 

 of years, has collected bacteria from the stools of pellagra patients and from 

 corn meal or bread supposed to have been the food of such patients at the time 

 of intoxication. The cultures obtained were inoculated on sterile corn meal 

 and fed to chickens from 2^ to Si months old. One of the chickens so fed con- 

 tracted a disease which symptomatically resembled pellagra in man. 



Tuberculosis of fowls, S. F. Edwards (Ontario Dept. Agr. Bui. 193, 1911,
