Treatment. — If the horse put his fore-legs down heel first, put on a 

 shoe worked very thin behind, such as described by Broad as follows : 

 " Extremely stout, wide-webbed, and long bar-shoes, make from iron 

 about twice the ordinary thickness of those of the particular animal 

 under treatment; make them gradually thin from behind the quarters, 

 so that the heel part of the shoes may be as wide and thin as possible, and 

 fitted rocker fashion to allow the weight of the horse to be on that part; 

 put them on with leather soles, using only suflQcient nails to insure their 

 staying on for two or three days." If, on the contrary, the horse walks 

 on his toe, shoe with a high-heeled shoe. 



Fomentations of hot water with laudanum, an ounce to a quart, will 

 allay the pain. Afterward apply blisters to hasten the ossific process. 

 The fly blister may be used, or biniodide of mercury, as preferred:

ANCHYLOSIS. 



Synonym.— Stiff joint. 



Definition. — Anchylosis or stiff joint is a result of previous disease, 

 rather than a disease itself. It is occasional by the presence of deposits 

 which have resulted from previous inflammation in the structure of, or 

 in the neighborhood of the joint. It consists in more or less complete 

 consolidation of the parts within or around the articulation. 



Anchylosis may arise from thickening and induration of the fibrous 

 capsule, or from the formation of fibroid bands within the joint; or it 

 may be caused by partial or complete erosion of the cartilages and syno- 

 vial membranes; their place being supplied by a fibroid or a fibro-cellular 

 tissue, by means of which the articular ends of the bones are united. Or 

 it may arise from shortening, contraction, or wasting away of the mus- 

 cles which in health move the joint. In other cases the anchylosis may
