II. — The appearances whicli these spots present are 

 peculiar. Some are round, others are of an irregular form. 

 The hair ia connection with them is of a dirty grey colour ; 

 the spots appear, in fact, as though they had been dusted 

 with fine grey-coloured powder, and afterwards a gummy 

 fluid dropt amongst it, and there allowed to remain until the 

 whole became dry and encrusted. 



III. — If I place my forefinger firmly upon one of these 

 encrustations, the crust is readUy forced aside, and a raw 

 surface is exposed, which upon examination with a common 

 magnifying lens I find to consist of a number of minute pits 

 or cavities, many of which are filled with purulent matter ; 

 while running round the border of each of these cavities ia a 

 delicate red line of variable thickness. 



The symptoms as described above are such as will be fomid 

 peculiar to every case of the disease. 



The Patho&onomic Symptoms are the circular form of 

 the sores, and the raw swrfaces which are exposed to view when 

 the crusts are removed. 



Tebatment. — Eingworm, like Mange, requires to be treated 

 topically. The disease is not difficult to cure. The best topical 

 applicants in general are, — Iodine and the Liquor Arsenicalis. 



Iodine. — The Iodine may be applied either in the form of 

 tincture or as ointment. If the tincture is used — first remove 

 the encrustations, then apply the remedy by means of a camel- 

 hair pencil. The sores should be painted with the drug, at 

 least twice a day, for several days in succession. The oint- 

 ment should be made as follows : — 



Iodine ... ... ... 1 drachm 



Lard ... .... ... 1 oz.
