high up as the groin. They should be opened and the matter 

 let out. 



Take Sulphate of Zinc 



Sugar of Lead, ....... 



Water, 



Mix, and bathe the legs with it once a day. Or, 



Take Carbolic Acid, ..... 6 drams. 



Water, ........ 1 pint. 



Mix, and use as above. 



Grease Grease-heel. This results from neglected 



c 



scratches. It is not contagious; nor are parasites present, un- 

 less they occur merely by accident. If grease is allowed to 

 run on, without being checked in its progress, it takes on a kind 

 of fungoid growth. It then presents an appearance something 

 like a bunch of grapes. This is called tl}e grapy stage, in 

 which there is a very offensive smell. 



CAUSES. Sudden changes in temperature; washing and not- 

 drying the legs; standing in filthy stalls; high feeding with- 

 out exercise; allowing a blister to affect the hollow of the 

 heel, just under the fetlock; getting the foot over a halter- 

 strap, etc. 



SYMPTOMS. At first a slight swelling, and (if in a white 

 horse) redness around the heels; the hair stands out; the heels 

 are hot and tender ; fissures or cracks appear in the heels, in 

 some cases extending up to the fetlock. There is a discharge 

 of matter, also, and the horse walks stiffly, almost lame. 



TREATMENT. If it has attained the grapy stage, it is diffi- 

 cult to cure it. If the animal is healthy and fat, give bran- 

 mashes for a day or two, and then dissolve seven drams of 

 aloes in hot water, and give when cool. If the hair stands out 

 much, clip it off, and apply a poultice of flaxseed meal, with a 

 little carbolic acid added, to destroy the bad smell. Then bathe 

 two or three times a day with 



Sugar of Lead, ....... 40 grains. 



Water, ........ 1 ounce. 



Or Chloride of Zinc, ...... 40 grains. 



Water, 1 ounce.
