lia, J. A. GiLRUTH {Proc. Roy. Soc. Victoria, n. scr., 25 {1912), No. 1, pp. 15- 

 22). — A historical account. 



The hypodermic affection of cattle. — The ox warble, Coppens {Ann. MM. 

 V^t., 62 {1913), Xos: 6, pp. 309-328; 7, pp. 3S-^-3SS) .—The first part of this 

 paper relates to losses caused by this pest through its injury to the hide, 

 flesh, etc.; the second part to its biology; and the third part to methods of 

 control. 



Bush sickness investig-ations, C. J. Rkakes and B. C. Aston {Jour. Agr. 

 [New Zeal.], 6 {1913), Nos. Jf. pp. 399-401, fig. 1; 6, pp. 616-624, figs. 2).— These 

 reports relate to experiments in which various top dressings were applied to the 

 soil and cattle and sheep then grazed upon the treated pastures. The best 

 results were obtained in the case of cattle with soil dressings of (1) supeiiDhos- 

 phate, (2) sulphate of iron, (3) blood and bones, and (4) guano; in the case of 

 sheep, with (1) sulphate of iron. (.2) basic slag, and (3) superphosphate. 



Vaccination ag-ainst g-angrenous mammitis in sheep and g-oats, J. BRiDRf; 

 {Bid. Soc. Cent. MM. Vqt., 90 {1913), No. S, pp. i8//-JS7).— This condition, with 

 the vaccine originally used against it, has been previously discussed (E. S. R., 

 19, p. 1185). The work has now been continued for the purpose of obtaining a 

 vaccine which will produce the smallest amount of lesions post-injection. Some 

 tests with sheep are included, from which the conclusion is drawn that it is 

 possible to obtain immunity against this condition by the treatment recom- 

 mended. 



Directions for using antihog cholera serum, J. F, Mitchell {California Sta. 

 Circ. 106, pp. 3-14, fiO^. 6). — A detailed account of the manner of immunizing 

 hogs against hog cholera. 



Virulent anthrax bacilli in the saliva of an affected horse, J, G. T. Arntz 

 {Berlin. Ticrarztl. Wchnschr., 20 {1913), No. 36, p. 640; abs. in Vet. Rec, 26 

 {1913), No. 1311, p. 2J7).— The author records the finding of virulent anthrax 

 bacilli in the saliva of an affected horse showing considerable swelling of the 

 throat. He thinks that transmission of the disease is possible by direct contact 

 through the saliva. 



The bacteriology and vaccine therapy of distemper in horses, W. Lintz 

 {Jour. Expt. Med., 17 {1913), No. 5, pp. 511-516).— ^egatixe results were 

 obtained in the attempt to immunize sick animals passively through the injec- 

 tion of serum from horses which had recovered from the disease. A vaccine 

 consisting of 800,000,000 each of the pneumococcus and of the bacillus isolated, 

 injected subcutaneously in the region of the neck, had a curative effect. An 

 immunity conferred by vaccination with 50,000,000 of each organism apparently 

 does not last longer than one year, though it lasts much longer if 3 inoculations 

 are given at intervals of 3 days. By vaccinating affected as well as unaffected 

 horses the following year the epidemic was promptly eradicated, not a single 

 case proving fatal. 



The diagnosis of dourine by complement fi.xation, J. R. Mohler, A. Eich- 

 HORN, and J. M. Buck {U. 8. Dept. Agr., Jour. Agr. Research, 1 {1913), No. 2, 

 pp. 99-107). — Dourine, which is caused by Trypanosoma equiperdum, was first 

 seen in the United States in 1886 and was noted at later periods in Nebraska. 

 South Dakota, and Iowa, and in Montana in 1912. The disease when present 

 in a chronic or latent form is difficult to diagnose, and a microscopic examina- 

 tion of the body fluids, etc., often fails to reveal the causative organism, although 

 it may occasionally be found in the serous exudate of the plaques and also in 

 the fluid obtained from the affected genital organs and in the edematous fluid 

 obtained from the affected genital organs of stallions and mares. In Montana 

 only a limited number of animals were clinically affected.
