a firm but regular pressure must be applied oil 

 it by means of layers of tov/, over which may be 

 placed a piece of stiff leather, kept in its situation by 

 means of cross bars of iron placed under the shoe. 

 The dressing should be repeated every other or every 

 third day, as the growth of the fungus appears more or

 very luxurious, to dress every day is m.uch more 

 proper. I have in some very inveterate cases found 

 much benefit from sprinkling over the fungus, before 

 I applied the Paste, a powder of equal parts of red 

 precipitate and alum. It is to be remembered in the 

 cure of canker, that though pressure is one of the 

 great means of cure, this pressure ought not to be 

 made by the hoof; on the contrary, wherever this 

 binds in on the affected part, it must be taken away, 

 m- at least thinned sufficiently.

A COLD. 



A cold, as applied to disease, is what in human 

 medicine is termed catarrh, and in old books of far-

 with more or less violence, the fever is more or less, 

 and the disease becomes formidable or trifling. 



A cold is caught from exposure to cold, particu-
