110 HEPWORTH, ON THE MICROSCOPE. 



I was mistaken. To my surprise (in so young a man) I found 

 abundance of Sa7'cina Ventriculi amongst the secretions attached 

 to the hair. I prescribed, and the man got well in three 

 weeks. Had I not accidentally made the discovery, he might 

 have gone on vomiting three or six months longer. 



J. W., aged twenty-eight, complained of great pain and irrita- 

 tion on micturition, and stated that he passed great quantities 

 of matter. On examining the secretion, I concluded from its 

 appearance, together with the symptoms, that the matter it 

 contained was pus ; but with the aid of the microscope I 

 found it to be triple phosphate. I mentioned this case to a 

 friend, a (microscopical) sceptic, who observed that I might 

 have ascertained that by chemical analysis. I admitted it ; 

 but such a tedious process would have taken up too much 

 time ; whereas, with the instrument, I convinced myself of 

 the fact in a few seconds, and was able immediately to give 

 an opinion as to the probable result. I may further state, 

 that the man, although so young, had lost all his upper teeth, 

 and the first step towards his improvement was to procure an 

 efficient set of these necessary articles : this he succeeded in 

 doing (thanks to the dentists), and there was a gradual return 

 to health, which I attribute more to the dentist's skill than to 

 any other remedy. 



T. v., a boy five years old, had general anarsarca after 

 scarlatina : there was a brownish deposit in the urine. On 

 examination I found it contained altered blood discs (having 

 the appearance of toothed wheels), triple phosphate, abund- 

 ance of casts of the tiihuH uriniferi, and, I thought, a few pus 

 globules (they might be mucous), but no brown epithelial 

 scales, which is a usual accompaniment with casts, as far 

 as I have remarked. The urine coagulated on the addition 

 of nitric acid. These appearances told a tale, which could 

 not have been so fully known without the aid of the micro- 

 scope. 



1 received from a friend a substance stated to be a portion 

 of a concretion passed per anum by a patient at the Man- 

 chester Infirmary : the case was one of Dr. E. Wilkinson's, 

 who has kindly furnished me with some particulars, a few of 

 which I shall state. R. L., aetat fifty-two, a weaver, four 

 years ago began to complain of pain in the stomach and right 

 side ; it was so severe at times that he could not retain the 

 erect posture : soon after he perceived a fulness in the side, 

 the tumour gradually increased, and about two years ago
