In cases v/here cracks appear, the treatment will greatly 

 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 vitri'i], 

 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 ])c 

 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 

 the 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 wdien 

 sufliciently incorporated, allow the mixture to stand until 

 nearly cold, then add the calamine, and stir tliem 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, Avhich will stimulate them 

 til heal more speedily. Administer the following diuretic : — 

 Turpentine . . -g ounce,
