888 EXPERIMENT STATION REOOED. 



may be named after the parasites which produce them, i. e., piroplasmosis (due 

 to Piroplasma [or Bahesial cahaUi Nuttall, 1910) and nuttalliosis (due to 

 Nuttallia cqiti Laveran, 1910, Franca, 1909)." 



A further contribution on the diagnosis of pernicious anemia of the horse, 

 E. Abderhalden and W. Buchal (Arch, Wiss. u. Pralct. TierlieUk., 37 (1911), 

 No. 3, pp. 309-313). — This is a continuation of the investigation previously 

 noted (E. S. R., 24, p. 392). The authors' studies led them to consider the 

 determination of the inhibitory power of serum an important aid in the recog- 

 nition of pernicious anemia of the horse. 



On the inhibition of saponin by the blood (serum and erythrocytes) of 

 horses suffering from pernicious anemia and from glanders, E. Abdeehaxden 

 and A. Weil (Arch. Wiss. u. Pralct. Tierheinc, 38 (1912), No. 3, pp. 2k3-2J,5).— 

 Continuing the investigations above noted, the authors find the inhibitory power 

 of the blood of animals suffering from pernicious anemia to be very great whftii 

 compared with that of animals affected by glanders or septicemia, and to 

 exceed that of any disease of the horse thus far met with. 



"Aphis foot" of horses in the Tamworth district, W, W. Fkoggatt (Agr. 

 Gaz. N. S. Wales, 22 (1911), No. 9, pp. 789-791, figs. 2).— The author finds that 

 aphis foot, a disease that appears at irregular intervals during the summer 

 when grass and lucern are growing most luxuriantly, is due to a mite closely 

 allied to Sijmljioies communis equi, the form that causes foot mange in horses 

 in the United States. " The name aphis foot has been given to this infestation 

 by the local farmers because, at the time when it first appears, the common 

 green aphis is abundant upon the lucern." 



'* I can find no reference in any reports on these mites in America to the re- 

 markable fact that the white legs and white patches on the animals are always 

 the first parts infested by these mites in Australia ; and it is also evident that 

 the foot mange of the horse in the United States, if identical with aphis foot is 

 not such a serious infestation as it is in Australia." 



Report of the veterinary department, R, A. Craig (Indiana Sta. Rpt. 1911, 

 pp. Jfi, 50).— During the year ended July 30, 1911, 1,262,296 cc. of antihog 

 cholera serum, or sufficient to vaccinate 31,557 hogs, was produced by the 

 department. " One hundred and fifty hyperimmune hogs were used in the 

 production of this serum. During the year 79 hyperimmunes were given a final 

 bleeding and killed; 57 hogs were hyperimmunized, and 14 hogs died from the 

 injections of virulent blood and injuries received in handling them. Twenty- 

 three bleedings were the greatest number for any one hjToerimmune. This hog 

 was used for serum production 7 months and produced during that time 34,860 

 cc. It received injections of virulent blood amounting to 18,900 cc. The in- 

 traperitoneal method of producing a hyperimmune hog was used, but it was 

 discarded because of the unsatisfactory results following its use." 



In the herds from which complete reports of the results were received, there 

 was an average loss of 2.25 per cent in the vaccinated herds, and 9.5 per cent in 

 the treated herds. 



The work is said to have shown that when 3,000 cc. of a virulent normal salt 

 solution are injected into the abdominal cavity of a virulent blood hog weighing 

 100 lbs. it is not of sufficient virulence to produce potent serum. Smaller injec- • 

 tions or about 20 cc. of normal salt solution per pound of body weight have 

 proved more virulent and may be considered one-half as valuable as cholera 

 blood in the production of the hyperimmune. 



Feeding experiments with Tilletia. A contribution to the hygiene of 

 nutrition, A. Scheunekt and E. Lotsch (Ztschr. Infektionskrank. u. Eyg. 

 Haustiere, 9 (1911), No. 3-^, pp. 177-187). — Experiments conducted in which 

 swine of various ages received large quantities of smutty food (Tilletia Icevis 

 and T. tritici (caries) gave negative results in that no ill effect was observed.
