Experiments in protective inoculation against contagious coryza with 

 dead streptococci, T. Km Wonatsh. Prakt. Tierheilk., /: (19 p. 863- 



S67). — The experiments reported in this paper were carried ou1 on colts. It was 

 found possible to immunize colts to a considerable ext< nl by inoculating them with 

 dead cultures of the streptococcus of contagious coryza. The method, however, has 

 little to recommend it in actual practice, Bince in order to obtain a protective immu- 

 nity 6 or 7 treatments musl be given. Passive immunity which maybe produced 

 by means of injections of serum 1 kis only a shorl duration. 



Kimberley disease in horses, R. E. W'kii; i i m. Jour. Dept. Agr. West. 

 12 (1905), No. t, pp. 60-6S). This disease has a course of variable duration and is 

 characterized by symptoms of congestion and derangemenl of tin- brain. 



It appears that the extraordinary mortality which occurs from attacks of this dis- 

 ease '-an not he attributed Bolely to one cause. The presence "t' parasites, however, 

 particularly Spiroptera megastoma, maybe 1< •« ,U» ■, 1 upon as a predisposing cause, in 



connection with coarse forage and the ingestion of large quantities of green f 1. In 



treating the disease the author recommends antipyrin :: times daily in doses of l 

 dram together with a mixture containing \ dram calomel and .] oz. ginger. 



A skin disease in horses affecting only the white markings, E. E. M \i;n\ 

 | Vet. Rec, is {1906), No. 922, pp. 628, 629).— In Calcutta the author observed a 

 number of cases of skin disease in Australian horses which had just been landed. 

 The white parts only were affected and appeared as if blistered. The disease was 

 attributed to an attack of insects, bul the exacl species was not known. 



Osteomalacia in Tonquin, J. Sourrel (Rev. Gen. Med. Vtt., . 

 pp. $88-248, figs. ■>'). — During the years 1901-1904 the author had occasion t<» study 

 osteomalacia in horses and mules in Tonquin. 



It was found that the disease appears after a varying period following upon expos- 

 ure or introduction to an affected region. The usual period ranges from 6 months to 

 2 years. Animals first appear lame and depressed, later malformations may appear 

 particularly in the form of enlargements of the Hat bones and shorl articular bones. 

 Fractures of the long bones in the leg may occur at any time during the course of 

 the disease. Ultimately the stage of extreme cachexia results, so thai progn 

 always serious. 



It was found that osteomalacia occurs in regions where there is plenty of lime in 

 the soil and in the forage plants as shown by analysis. The absence of lime could, 

 therefore, not have been the cause in the cases observed by the author. It is 

 believed that the disease is of infectious origin, but the organism has not been 

 isolated. Therapeutic treatment is not very successful, but some benefit was derived 

 from the use of pilocarpin, purgatives, strychnin, and feeding green forage plants, 

 for which purpose the author recommends the use of Panicum sequinum. 



Use of artificial impregnator in horse breeding, L. L. Lewis and W. L Eng- 

 lish ( Oklahoma Sta. Circ. 5, pp. 8, Jigs. 6). — The importance and general use of the 

 artificial impregnator by stockmen led the station to Bend out a circular letter of 

 inquiry regarding the methods in common practice. 



It appears that there are two forms of impregnator in general nse, the Btraight ami 

 the curved. The latter is preferred, and may he used with <>r without a vaginal 

 speculum. If a breeding bag is used on the stallion a Bpeculum will be found 

 unnecessary. Before service it may he well to close the neck of the nterus with a 

 rubber plug. After service the plug is removed at once, a part of the semen injected 

 into the uterus and the rest used to impregnate other mart-. Before transferring 

 the semen the syringe should be warmed in water at a temperature of 100 P. and 

 the transfer should take place without delay. 



Experiments in preserving semen in vials for a period of '■> hours or more Bhowed 

 that a temperature ot 100-103° F. is less favorable to the vitality of the spermatozoa 

 than 85° F. In Oklahoma the breeding bag is used by about two-thirds of those who
