212 COMPENDIUM OF THE VETERINARY ART. 



the concave part or cleft of tlie sensible frog 

 in a state of ulceration, which of course ren- 

 dered it incapable of secreting horny, matter, 

 and proved a constant source of thrushes. 



With respect to those thrushes which attack 

 the hind feet, and which sometimes, though 

 rarely, happen also in the fore feet, independ- 

 ently of the aboA e cau^e, a ditferent treatment 

 is required. When the discharge has existed 

 for a considerable time, by stopping it hastily 

 we frequently produce intiammation and swell- 

 ing of the legs : still it is necessary to check 

 the disease, since, if neglected, it sometimes 

 degenerates into that dangerous disease termed 

 canker. It is advisable, therefore, in such 

 cases to keep the bowels open by the following 

 laxative ball, given every morning until the 

 desired effect is produced, and repeated oc- 

 casionally. The best application for the frog 

 is tar, and one of the above astrincfents : other 

 remedies, however, have be^n strongly re- 

 commended, among which are powdered 

 iinie, Eg}ptiacum, tincture of mynh, and 

 other astringents. This treatment will be 

 greatly assisted by two or tiiree hours' exer- 

 cise every day, and frequent hand-rubbing to 

 the legs.
