In cases where cracks appear, the treatment will great!) 
depend upon their extent and depth : when they are small, 
the following lotion will be found beneficial :— 
Blue vitriol (or sulphate of copper) 2 drachms, 
Water .... 1 pint; 
or four drachms of alum may be substituted for the vitriol, 
with the same quantity of water. This will speedily dry 
them up and close them. When the cracks are large and 
deep, and discharge an ichorous matter, accompanied with 
considerable lameness, a poultice of lintseed-meal will be 
indispensable ; but when the discharge is thin and accom¬ 
panied by a fetid smell, it will be necessary to mix an 
ounce of finely powdered charcoal with the lintseed-meal, 
as it is a powerful antiseptic ; or a carrot poultice may be 
used in its stead : the carrots to be boiled and mashed. 
The poultices to be applied until the inflammation has 
abated, and a thicker and more healthy matter flows from 
jhe cracks. After this apply the following ointment 
Resin .... 1 ounce, 
Calamine powder . . 1 ounce, 
Lard .... 3 ounces. 
Let the resin and lard be melted together, and when 
sufficiently incorporated, allow the mixture to stand until 
nearly cold, then add the calamine, and stir them well 
together. This precaution is necessary, as the calamine 
would fall to the bottom if the mixture were thin. During 
the time of the above application, the cracks should be fre¬ 
quently washed with the solution, which will stimulate them 
to heal more speedily. Administer the following diuretic :— 
Turpentine . . ^ ounce, 
Ginger . 
Purified nitre . 
Lintseed-meal
