arises. Perhaps a breast-band can supplant the collar. The 

 term " sit fast " is a})plied to an indolent sore u])on the back. 

 It is a scar imbedded in a zone of dead — or practically so^ 

 tissue. Unction with iodine ointment will often excite repara- 

 tive inflammation ; if not, the part recjnires surgical inter- 

 ference. 



NETTLE RASH (URTICARIA). 



Nettle rash is characterised by the appearance of numerous 

 variously sized oval or round elevations upon the skin, especi- 

 ally about the trunk. These " weals " cause a great deal of 

 irritation, yet the skin remains intact. The departure of the 

 " weals " is almost as sudden as that of their onset. Distur- 

 bance of the digestive and nervous systems are probably at the 

 root of the whole affair. 



Treatment. — Give a change of food, and a mild dose of 

 Barbados aloes. Green food can be allowed. To aUay the 

 irritation, bathe the parts with a strong solution of baking 

 soda. Boracic acid ointment is also a useful appHcation for 

 this purpose. 



RING-WORM. 



This ring-like diseased conchtion of the skin is due to a 

 microscopic parasite known as tyycophvtoii tonsurans. The 

 patches have a scurfy and stubbly appearance. 



Dress with iodide of sulphur ointment or ])aint wiiii iodine.
