158 " THE HORSE AND ITS DISEASES. 



Lameness in the Shoulder. 



It is easily distinguished from lameness in any other 

 part, by the horse dragging his toe and moving his foot 

 in an outward circular manner at every step. Fomenta- 

 tion to the part four times a day, one hour at the time, 

 will be found extremely beneficial ; the animal should 

 not be allowed to lie down during the time. If lameness 

 appears obstinate, a blister should be applied and 

 repeated, if necessary, composed as follows : — 



Spanish Flies 4 drachms. 



Spirits of Turpentine 4 , , 



Hogs' Lard 3 ounces. 



Mixed together and rubbed on the part for twenty 

 minutes. 



CLASS IX. 



STRING HALT — BROKEN KNEES — WIND GALLS — SPLINTS — STRAIN 

 IN THE BACK SINEWS — GREASE. 



String Halt. 



String halt is evidently an aff'ection of some of the 

 nerves which communicate motion to these muscles. It 

 is an irregular action of the nervous energy, but what 

 particular fibre is affected, or what muscle is chiefiy 

 spasmed has never been ascertained. The horse's action 

 is unpleasant to the rider, but it cannot be denominated 

 unsoundness ; on the contrary, the general opinion of 

 farriers of great experience is, that a horse with string 

 halt has more than usual strength and endurance. 



By some it has been supposed to exist in the spinal 

 marrow, and by others, to be situated in the nerves 

 supplying some of the muscles of the leg. ISTo cure has 

 ever been discovered.
