The Bacillus abortivus equinus as an etiological factor in infectious 

 arthritis of colts, E. S. Good and W. V. Smith {Jour. Infect. Diseases, 15 

 {1914), iS^o. 2, pp. 347-349). — The authors have isolated the organism causing 

 infectious abortion in mares from a colt affected with infectious arthritis. "At 

 the present time it is impossible to say as to what role the B. abortivus equinus 

 plays in the disease of infectious arthritis of colts, but that it is capable of pro- 

 ducing this disease, as are the other germs noted by investigators, is evidenced 

 in this instance." 



The etiology of pyemic arthritis in foals, F. W. Schofield (Jour. Infect. 

 Diseases, 15 (1914), ^^o. 2, pp. 409-416). — The author's studies of the charac- 

 teristics of the bacillus which causes pyemic arthritis in foals show it to belong 

 to the colon-typhoid group and to be closely related to Bacillus parati/phosus B. 



Attention is called to the fact that the organism isolated, and here described, 

 has a very close relationship to the one recently isolated by Good (E. S. R., 

 29, p. 779) in contagious equine abortion. " In cultures the only difference 

 observed is that the bacillus of equine abortion causes fennentation in raflSnose 

 while my organism does not attack this carbohydrate. However, difference in. 

 strains would readily account for this. The most convincing evidence that 

 these organisms are but strains of the same species is that they can not be- 

 differentiated by means of the complement fixation test. Serams giving com- 

 plete fixation with antigen prepared from my organism also give fixation in 

 corresponding dilutions with antigen prepared from the bacillus of equine abor- 

 tion. With characteristics that correspond so closely, these organisms appear 

 to be but strains of the same species, and it is quite probable that the same 

 organism may be responsible for both septic arthritis and abortion. These dis- 

 eases commonly coexist in the same locality ; furthermore, it is of frequent 

 occurrence for a mare to abort one season and during the next to deliver a colt 

 that develops septic arthritis. The more one studies the clinical history of 

 these diseases the more convincing becomes the probability of their common 

 etiology in many instances." 



A text-book of horseshoeing for horseshoers and veterinarians, A. Lttng- 

 wiTz and J. W. Adams (Philadelphia and London, [1913], 11. ed., pp. 216, . 

 figs. 229). — In this eleventh edition of Lungwitz's work, J. W. Adams assumes ' 

 entire responsibility owing to the author's having reached the age of retire- | 

 ment. In revising the tenth edition, translated in 1904, many chapters have | 

 been rewritten and illustrations withdrawn and others added in order to keep '\ 

 pace with the progress in farriery. The effect of weight in the shoe in altering ■ 

 the flight of the foot is discussed, as are rubber pads, so widely used in the 

 United States. Attention is directed to many innovations of more or less value 

 that have appeared during recent years. 



The various chapters deal with (1) the gross anatomy of the horse, (2) 

 the foot in its relation to the entire limb, (3) shoeing healthy hoofs, (4) shoeing 

 horses that forge and interfere, (5) winter shoeing, (6) hoof nurture, (7) general , 

 remarks concerning the shoeing of defective hoofs and lame horses, (8) inflam- 

 mations of the pododerm (pododermatitis), (9) defects of the hoof, and (10) 

 shoeing mules, asses, and oxen. 



Vaccine treatment of chicken pox in fowls (Wisconsin 8ta. Bui. 240 (1914), 

 pp. 36, 37, fig. 1). — In experiments with the vaccine treatment of chicken pox, 

 first suggested by Manteufel (E. S. R., 23, p. 792), highly beneficial results were 

 obtained by F. B. Hadley, B. A. Beach, and J. G. Halpin in ailing as well as 

 in bealthy fowls. 



The vaccines were prepared by grinding diseased tissues, such as pox scabs 

 and afl'ected membranes, and subjecting them to a temperature of 55° C. (131" 

 F. ) for one hour. " Four hundred and forty fowls were treated five days apart
