 skin, circular in outUne, similar to those observed 

 in ringworm. 



The spots are at first very small, and may appear 

 upon any part of the body, head or limbs. Some- 

 times they attain the size of a two-shilhng piece. 

 Treatment comprises dressing the parts with the 

 following lotion: 



Sulphurated potash ... 3 ozs. 

 Boiling water . . . . i pint. 



Apply to all the diseased patches daily, taking 

 particular care to thoroughly wet the skin. Five- 

 drop doses of Fowler's solution of arsenic should 

 be given with the food, three or four times a day; 

 but as hounds are commonly fed only once a day ten- 

 drop doses can be allowed for a full-grown hound, 

 but this should not be continued for longer than 

 three weeks at a time, to be followed by a four- or 

 five-grain pill of calomel. At the end of a week or 

 ten days' time the arsenic may be repeated. This 

 method of the administration of arsenic is applicable 

 in the case of all skin diseases in hounds, and it may 

 be accepted, as a general rule, that it is a drug which 

 proves beneficial in most chronic skin diseases.
