charge, which should be kept up with hot fomentations. Firing 

 reduces the inflammation which is the cause of the unnatural 

 growth of bone, and in that way acts beneficially. 



Eingbone is a growth of bone from bone, situated around the 

 coronet, mostly near the pastern joint, at other times just above it ; 

 and not unfrequently the coffin bone and pastern bone become 

 united together by bony growth. Eingbones are the result of 

 hereditary predisposition, structural organisation, and accident. 

 The disease may be produced by a blow to the part, and from 

 the efforts made to increase speed, when concussion causes injury, 

 inflammation, and consequent exostosis to the bones of the pastern. 

 As to treatment, remove the shoes from the horse's feet, and turn 

 out to grass. If this, after a fair trial, fail, then the treatment 

 for spavin and other exostoses must be resorted to, such as blister- 

 ing the affected part, and keeping the animal on a low diet. 



EINGWORM. 



Apply, daily, over and around the ringworm an ointment con- 

 sistino- of one drachm of the iodide of zinc to the ounce of lard.

EOAEING AND WHISTLING. 



An able correspondent of the Fldd thus describes the various 

 methods of detecting this malady : "' Eoaring and whistling are 

 generally detected during a canter ; very few horses manifest the 

 defect during a walk or slow trot ; and some animals, when only 

 affected to a trifling extent, give no evidence of unsoundness during 

 a gallop. In many cases of incipient whistling the sound is only to 

 be distinguished at the moment the canter is commenced. After a 

 few paces the breathing becomes perfectly natural, and continues so 

 until the horse is pulled up for a time, and again started after a few 

 minutes' rest ; for this reason it is very important that doubtful or 

 disputed cases should be examined after rest ; and, if possible, the 

 examiner should be upon the horse's back, in order that he may 

 have the opportunity of listening to the breathing at the instant the 

 animal commences to canter. Presuming that the horse under 

 examination bears this test well, and that neither to the listener in 

 the saddle or to anyone standing near is any unsoundness apparent. 

 the next step will be to stop the animal suddenly in his career, and 

 listen with the ear placed conveniently near to the openings of the 

 nostrils. Very frequently a slight whistle will be detected in this 

 way, when no unhealthy sound can be heard while the horse is can- 

 tering or galloping.
