THERAPEUTIC TREATMENT. 333 



insidious effects of this long-continued irritation ; or excite anotlier 

 and healthier and more powerful action, and before which the other 

 must succumb." And, moreover, Mr. Youatt thinks that, while 

 the copper answers this end, it " has a pecuhar local determina- 

 tion to the Schneiderian membrane ;" and, also, that its effect '' in 

 healing abrasions and arresting nasal gleet is undeniable." The 

 following case, sent me by my relation, Mr. Charles Percivall, ex- 

 hibits all the appearances of recovery from the employment of 

 sulphate of copper in solution : — 



While I was (veterinary surgeon), says my cousin, in the Enniskillen Dra- 

 goons, a squadron of the regiment, then stationed in Ireland, became detached 

 for upwards of a fortnight ; during which time the horses were cantoned in 

 filthy close stabling, wherein glandered horses were known frequently to have 

 stood on former occasions, glanders being no uncommon occurrence in this 

 part of the country. On the return of the squadron to head-quarters, one of 

 the finest horses belonging to it — in perfect health at the time he went out — 

 was brought to me on account of a copious discharge from his off nostril, 

 accompanied by extensive ulceration upon the same side of the septum nasi, 

 and tumefaction of the off submaxillary lymphatic glands. He was imme- 

 diately shut up in a box appropriated for contagious subjects, bled (being in 

 high condition), and had his glands blistered ; and was ordered to take, daily, 

 half an ounce of sulphate of copper in solution, a dose that was afterwards 

 increased to an ounce. On the ninth day, being off his feed, the medicine 

 was discontinued. On the eleventh it was resumed. On the fifteenth, for the 

 same reason as before, it was again omitted. On the seventeenth the dose 

 recommenced with was jvj, which he continued to take with but few omissions 

 until the fifty-seventh day. By that period the ulcers, which for some time 

 past had been gradually growing cleaner and healthier , were quite healed ; 

 and the discharge from the nose, which likewise had been for some time 

 diminishing, had also ceased. Apprehending, nay, looking for a relapse, the 

 animal was still detained in the infirmary box, and kept there for two months 

 longer before he was allowed to rejoin his troop. Twelve months afterwards 

 my cousin left the regiment ; up to that time the horse continued free from 

 disease. 



The Sulphate of Iron is a favourite medicine with Mr. 

 Turner, of Regent-street. He prescribes it, " not in nauseat- 

 ing, overwhelming doses, but dissolved in the water (the horse 

 drinks) in his bucket suspended in his box, so that the patient may 

 drink a little at a time, and as often as he pleases. Mr. Turner in-
