URTICARIA — GREASINESS OF SKIN. 269 



of the year in particular, on the approach of warm weather. 

 After freely bleeding and purging, I recommend a course of 

 alterative medicine. To the eruption, prior to ulceration, 

 applj^ either Goulard lotion, or salt and water. When sores 

 appear, let them be fomented daily, and dressed with some 

 escharotic or stimulating application, such as solution of lunar 

 caustic, or white vitriol, or alum ; and afterwards sprinkled 

 with astringent powder : charcoal, or common flour. 



I am quite persuaded eruptions appear in horses as in 

 children^ during the time of the cutting of the teeth. I 

 have seen large, irregularly-shaped " lamps" make their 

 appearance almost suddenly upon the neck, body, quarters, 

 and arms of young horses while cutting their tushes ; their 

 gums also being red, swollen, and feeling hot ; the pulse, 

 likewise, quicker; the animal dull, though not, perhaps, off 

 its feed. Lancing the gums is evidently indicated here, 

 though, like similar effects from other causes, this febrile 

 commotion once excited, will not subside directly ; and will, 

 therefore, be best met by aperients, loose diet, &c.

Slight inflammation of the skin, characterised by pro- 

 minent spots of a redder or paler hue than the neigh- 

 bouring parts. The pale spots are accompanied by a 

 feeble, circumscribed engorgement, which rarely continues ; 

 but re-appears with another attack. Sometimes, these are 

 covered by white vesicles, analogous to those which follow 

 the pricking of nettles.

 returned from grass, and is now, (Sept. 1835,) shedding the 

 coat, evinces an exceedingly greasy condition of the skin. 

 The coat feels remarkably soft and slippery, and the fingers, 

 after stroking it, are uncomfortably greasy. I have had
