solution of c-hloro-naphtholeum was applied to the horses twice a week until the symp- 

 toms disappeared. 



Malignant mold fungus disease of horses, J. de Haan {Ccnibl. Bakt. u. Par., 

 1. Alt., 31 {1902), No. 15, Orig., pp. 7o8~70S,fgs. ;?).— The author described a disease 

 of horses caused by a mold fungus, and which was characterized by lesions of the 

 skin and mucous membranes. The mucous membrane of the mouth, lips, and nose 

 are most susceptible to atta-ks of the disease. The pathological process gradually 

 spreads to tissue surrounding the primary focus, without regard to the kind of tissue 

 involved. The process extends more rapidly in the mouth cavity than in the skin. 

 Experiments in the administration of iodid of potash indicate that this remedy may 

 have in some cases a beneficial effect. Otherwise the diseased patches should be 

 removed at once by ojieration. 



Wandering bot-fly larvse, C. Lekn,i5s {Nor.sk Yd. Tids.skr., 14 {1903), No. 1-2, 

 pp. 39-42) . — The author reports in detail observations made on a horse infested with 

 bot-fly larva2. A number of the larvse were found under the skin, in which sitvia- 

 tions they produced abscesses of considerable size. Eleven such abscesses were found 

 in the lumbar region of the animal, and others were observed on other parts of the 

 body. 



Tibio-peroneal neurectomy for the relief of spavin lameness, W. E. A.Wyman 

 {Ne}r York: IT. A', .leakim, 1902, j>p. 30, fig. l). — The author presents a detailed 

 description of this modification of the operation for the relief of spavin lameness. In 

 all, 91 operations of this sort were performed. Of this number there was a healing of 

 the tibial wound in 65 cases, while the peroneal site healed in 40 cases by first inten- 

 tion; muscular hernia o(;curred in 8 cases, loss of the hoof in 3 cases, and septic 

 infection in 1 case. Four cases remained lame. There was a complete removal of 

 lameness in 55 cases, while a slight lameness persisted in 18 cases. 



Diagnosis of anthrax, O. Hosang {Arch. Wiss. u. Prakt. Thierh., 28 {1902), No. 

 3-4, pp. 372-380). — In experiments instituted by the author it was found that 

 when material from animals dead with anthrax was smeared on a cover glass in a 

 thick layer and allowed to dry, the anthrax bacilli retained their virulence for 2 

 or 3 days. During these experiments it was found that blood and spleen tissue 

 which were taken from mice or guinea pigs 2 days after death and preserved for 3 

 days at a living temperature, were still capable of producing infection in healthy 

 mice. Blood and spleen tissue taken from guinea pigs 4 days after death and 

 preserved for from 24 to 48 hours were still virulent for the majority of mice on 

 which experiments were made, as shown by the fact that 7 out of 8 inoculated 

 mice died of anthrax. It is believed by the author that this method of placing a 

 thick layer of infected tissue or other material upon a cover glass and allowing it 

 to dry is a valual)le one and permits the preservation of the material in a virulent 

 condition for a reasonable length of time. 



The pyocyanase of Emmerich and Iieow in experimental anthrax, L. 

 Taveknaki {Cmthl. Bakl. n. Par., 1. Ab(., 31 {1902), No. 1.5, Orlg., pp. 786-793).— 

 Experiments on guinea pigs and a rabbit indicated the favorable effect of the uce 

 of pyocyanase, in that death from experimental anthrax was postponed for con- 

 siderable time. Pyocyanase, however, appeared not to have the effect of prevent- 

 ing a fatal outcome of the disease. The edematous swellings observed in experi- 

 mental animals after inoculation were developed to a much le.'s extent when the 

 animals were treated with pyocyanase. 



Some observations on the Bacillus anthracoides, F. A. Bainbridge {Jour. 

 Path, and Bad., 8 {1902), No. 1, p>p. 117-120).— The author's observations on this 

 organism were made on material obtained from Chinese horsehair, Avhich had 

 already been subjected to a boiling temperature long enough to destroy all except 

 si>ore-bearing organisms. The anthrax bacillus was also found associated with B. 

 anthracoides. The latter organism is described as a straight, short, thick rod, which 

 usually forms chains of 8 or 10 bacilli, is motile, stains with aniline dyes, and does not
