becomes more aggravated with age, and as the value of animals afflicted 
with it, is depreciated by this unsoundness, it is important to be able to 
recognise the affection, when only slightly developed. It is advisable to 
have the animal turned from one side to the other, and then in the reverse 
direction. In cases of slight stringhalt, the peculiar convulsive twitching is 
often shown only as the animal turns one way. 
Stringhalt is a disease which generally comes on gradually, but cases 
where the malady has come on in the night are recorded. We are of the 
same opinion as Professor Williams, in considering that the chief cause of 
stringhalt is an inflamed condition of the nerves, supplying the affected 
limb. Stringhalt coming on more rapidly, is in many cases a rheumatic 
affection, due to cold, damp, or exposure. 
Although on the continent, methods of treating chronic stringhalt by 
certain surgical operations have been advocated, yet at present we are not 
able to say how far these methods have been successful. This subject, 
indeed, is at present engaging the attention of veterinarians at home and 
abroad. In cases where the symptoms become aggravated from any cause, ' 
or when the disease suddenly manifests itself, the animal should be rested ; 
and if the disease be due to rheumatism, the malady should be treated as we 
have already mentioned. In such cases nothing need be done locally, beyond 
hot water fomentations. When not traceable to rheumatism, rest, a dose of 
physic, hot fomentations, and three drachms of bromide of potassium, given 
in the drinking water three times daily, may prove serviceable, 
CHOREA, OR ST. VITUS’ DANCE. 
WE will now speak briefly of the disease called chorea, and better known in 
the human being under the name of St. Vitus’ dance. It is a peculiar 
disorder, characterised by irregular contractions of different muscles. It is 
not a common malady in the horse. It is usually traceable to hereditary 
predisposition, although mal-hygienic conditions, overwork, and exhaustion, 
may also act as exciting causes. Stringhalt itself may be regarded as a 
peculiar choreic disease. In treating chorea, it is necessary whenever it is 
possible, to remove the cause when that is to be ascertained. The general 
hygienic conditions should be attended to, the diet should be good and 
nutritious, and the work proportzoned to the strength of the animal. Internally 
half an ounce of Fowler’s solution, and three drachms of bromide of 
potassium, may be given twice daily in the drinking water. ‘ Shivering” is 
a peculiar disorder affecting the muscles of the back and posterior 
extremities. When a horse subject to this affection is backed or turned, the 
muscles of this region are thrown into a spasmodic condition, contracting 
and relaxing irregularly. The tail is often spasmodically elevated, and then 
depressed. When the horse is trotted forwards, the spasms are very seldom 
developed, but they may be brought into action by the head being rapidly 
turned round, ;
