be equal in size or one may be distinctly larger tban the others. Frequently the 

 space between them is stained less intensely than the remainder of the corpuscle 

 and this somewhat clearer space bounded by faint, thread-like lines with just 

 a suspicion of blue stain in them. 



"Occasionally ring-shaped bodies, faintly defined, with a slightly bluish tint, 

 are observed with usually 1, rarely 2 or 3, deeply stained granules situated 

 at the periphery of the ring. They are very minute and easily overlooked. 

 Whether the smaller forms bear any relation to the larger, ' coccus-like ' bodies 

 first mentioned remains to be determined. These bodies may be seen In slides 

 fixed in methyl alcohol and unstained. . . . 



"The frequency with which these bodies occur varies widely in different 

 cases. In some they are comparatively few in numbers, in others numer- 

 ous. ... A diligent search for them in blood films prepared from several 

 supposedly normal horses, several affected with ]ineumonia, influenza, strangles, 

 etc., and from several surgical cases has failed to reveal them." 



The " coccus-like " form is said to quite closely resemble the description and 

 photographs of the protozoan genus Anaplasma described by Theiler as the 

 cause of gall sickness in South African cattle. It is suggested that these 

 bodies may be found to represent a new species of Anaplasma. 



In sections of the liver from a tjTical case of equine anemia, stained by the 

 Gram-Weigert method, the author found inside the hepatic cells certain very 

 minute, ring-shaped bodies with a small granule at one side, at the periphery 

 of the ring. Search for them in sections of liver from several animals where 

 the liver showed various types and degrees of degeneration resulted negatively. 

 The author thinks these ring-shaped bodies to be too definite and too uniform 

 for degeneration products, as supposed by Todd and Wolbach (E. S. R., 25, 

 p. 89) in work with swamp fever. 



Studies on the etiology' of equine influenza, N. S. Feeey ( Vet. Jour., 68 

 (1912), No. IiJf2, pp. '185-197). — The data presented in this paper, which was 

 read at the meeting of the Society of American Bacteriologists at Washington, 

 D. C, in December, 1911, have been noted from another source (E. S. R., 27, 

 p. 86), 



The etiology of equine influenza (Vet. Jour., 68 (1912), No. 443, pp. 246r- 

 248). — This is a review of the paper noted above. 



Glanders of the lungs in horses with some notes on the serological detec- 

 tion of the disease, Schutz (CentM. Bakt. [etc.], 1. Abt., Orig., 64 (1912), 

 Festschrift F. Loeffler, pp. 87-99). — The glanderous nodules in the lungs of 

 horses are either hematogenic or bronchogenic in origin. The following varieties 

 of pulmonary infections with the glanders bacillus are mentioned and discussed 

 in detail: (1) A glanderous cellular or cellular fibrinous inflammation of the 

 lungs; (2) chronic (glanderous) indurative pneumonia and broncho-pneumonia ; 

 and (3) purulent bronchitis and peribronchitis. Mixed infections are also 

 described. The agglutination and complement fixation tests are good methods 

 for detecting this disease in horses. 



A contribution on the treatment of contagious pneumonia of the horse 

 with salvarsan, Jacob (Ztschr. Veterindrlc, 23 (1911), No. 8-9, pp. 40 6-41 1 ; 

 ahs. ill Berlin. Tierarztl. Wchnschr., 28 (1912), No. 32, p. 588).— In all of 12 

 cases of the pectoral form of influenza (brustseuche) in which the author 

 administered salvarsan intravenously the temperature sank to normal within 

 from 15 to 24 hours and continued so. 



Bovine variola in chickens, O. Casageandi (Bev. Intemat. Vaccine, 1 (1910),

 which has been scarified or rubbed with sandpaper, the specific lesions (Cy-
