PECULIAR TO HOKSES. 33 



When Gutta Serena comes on in a sIotv and insidious manner, 

 and has existed some time, it is sure to end in total Windness, but it 

 is often a sympathetic aftection, and subsides as soon as the disease 

 which gave rise to^it disappears. Whenever the affection is associ- 

 ated with -other derangements, a mixture of golden seal and ginger, 

 administered in two drachm doses once or twice daily, will afford 

 relief. 



PARTIAL PARALYSIS IN MARES DURING THE PERIOD 

 OF " HEAT » OR MENSTRUATION. 



My attention has often been called to 3Iares, the subjects of a 

 sort of hysterical affection, accompanied by partial paralysis of the 

 hind extremities. It is quite common for mares that are barren to be 

 afflicted with this malady, for the simple reason that they are often 

 the subjects of diseased ovaries. I once spayed a very valuable 

 mare, a regular hysterical subject, who, -during the menstrual period 

 was uncontrollable, yet was often afflicted with partial paralysis ot 

 the hind extremities. The operation was a perfect success, and the 

 mare was finally sold for the sura of fifteen hundred dollars. 



Partial paralysis, occurring in the male equine, is usually consid- 

 ered as incurable, and I think it is from the fact that most practi- 

 tioners resort to desperate means, in the use of strychnia, which, 

 when adminstered in popular doses, is better calculated to kill than 

 to cure ; the patients often die, secundum artem, poisoned by 

 Strychnine. 



All curable cases of partial paralysis may be benefited by the use 

 of antispasmodics^ which consist of camphor, Indian hemp, asa- 

 fcetida, musk or garlic; and this disease, like many others, is often 

 self-limited. A little patience, a small quantity of anti-spasmodic 

 medicine, given occasionally, will accomplish wonders, and often 

 save a valuable animal, which, when otherwise treated, would be sure 

 to die. As regards the " male," the affection is said to bo the pro 

 perty of the matured animal, very rarely affecting colts. Fast trot- 

 ters, omnibus horses, and animals subjected to extreme exertion, are 

 most liable to it. The disease in the male is supposed to be eccen- 

 tric, and therefore it is difldcult to say how it will terminate. It 

 generally ruins the horse. 



" STIFLE OUT." — [Luxation of the PateUa.) 



The Patella of the horse, or " Stifle-bone'"' as it is sometimes 

 called, corresponds to the knee-pan of the man, and performs the 

 same office. The position of the bone is at the lower part of Lhe 

 femur, and upper part of the tibia. The bone itself is kept in posi- 

 tion by strong ligaments, and in consequence of the presence of a 

 large prominence or condyle on the inner and lower part of the 

 femur. Dislocation inwardly very rarely, if ever, takes place ; the 

 bone is, therefore, in case of luxation — stijfie out — found on the outer 

 and lower part of the thigh.
