There are many other remedies for grease, but most of them are not 

 very efficacious. When all remedies prove unavailing, it is often 

 advantageous to turn the animal out to graze for a time. Some time ago, we 

 were called to a valuable three-year old stallion suffering from a very severe 

 form of grease. The disease began at the heels, and spread rapidly as far 

 as the hocks of both legs. Very large hard elevations grew quickly, and the 

 fetlocks were soon co\'ered with thickly-crowded masses of these unhealthy 

 excrescences. From them there oozed continually a thick fetid discharge. 

 Internal remedies proved unavaihng. The animal was cast, and through the 

 tissues diseased lines were drawn longitudinally with the firing-iron. In about 

 a month the horse was nearly well, though shortly afterwards he lost flesh, 

 and his appetite failed. He was then turned out to graze, and soon _ 

 recovered his strength. The legs also greatly improved. Unfortunately, 

 since the horse has come up, the affection has again broken out. In this 

 case, so inveterate is the disease, that when cured for a time it breaks out 

 again, and remedies, prove valueless. Just lately, we have had two similar 

 cases in older animals. These have been treated similarly with firing and 

 the administration of internal remedies, and are now cured. 



M ALLEN DERS x\ND SALLENDERS. 



The affection termed mallenders, when the skin behind the knees is attacked, 

 and sallenders, when the integument on part of the hocks is involved, is a 

 similar disease to ihat scaly condition of the skin on the human being, which 

 goes by the name of psoriasis. Psoriasis also sometimes affects the 

 integument of other parts of the horse, and is not very uncommonly seen in 

 front of the withers. It is a difficult affection to cure radically, and for this 

 reason it is regarded as constituting unsoundness. Of its causes we know 

 very little indeed, but overfeeding and heredity both seem to play their part 

 in its production. 



In these cases the diet should be laxative, and limited in amount. It is 

 well to commence treatment by the administration of a moderate dose of 

 physic. The patches should (when it is feasible) be poulticed, to remove the 

 scales, and they should then be anointed twice daily with ointment, made of 

 chrysophanic acid half a drachm, and benzoated lard one ounce. Internally, 

 two drachms of Fowler's solution, with six drachms of bicarbonate of 

 potassium,, may be given twice daily, in the drinking water, for a fortnight. 

 This treatment may then be discontinued for a week or so, and then, if 

 necessary, may be again resumed for a similar period. 



MUD FEVER. 



Mud fever is an inflammatory condition of the skin of the limbs, of a nature 

 similar to that of cracked heels. It depends upon similar causes, being 

 commonly brought on by washing the limbs in hot water after a day's work. 

 It may also be brought on after work in wet weather, by the irritating action
