522 PHILOSOPHICAL TRANSACTIONS. [anNO IZOQ. 



shake my belief at all ; for besides a nice examination of all the circumstances, 

 at first, I am still persuaded, that it came through the urethra, and was neither 

 conveyed, rior by any accident dropped into the pot, by such evidence as is little 

 short of demonstration ; as, that the tumour in the side of the belly vanished 

 wiih it ; with all those other symptoms which molested her, viz. strangury, 

 fetid and purulent urine, and have not now in 2 years made any return. 



I have a couple of other rarities to present to the Royal Society, one of 

 which is matchless, and to me wholly new. 



A girl in Plymouth, id years of age, had about the end of April a few hot 

 pimples rise on her cheeks, which bleeding and a purge or two cured. She 

 continued very well till about a month after, when her face suddenly turned 

 black, like that of a negro. This surprising accident much frightened the girl, 

 even to distraction, when n>y assistance was required. By the arguments I 

 used, and some composing an ti- hysterical remedies, the violence of her fits was 

 much abated ; I also directed a lotion for her face, which took off the disco- 

 louration, but it returned frequently, though not regularly, sometimes twice or 

 thrice in 24 hours, sometimes five or six times. It comes on insensibly, without 

 pain, sickness, or any symptoms of its approach, excepting a little warm flush- 

 ing just before it appears. It easily comes away, and leaves the skin clear and 

 white, but smuts the cloth that wipes it from the face ; it feels unctuous, and 

 seems like grease and soot or blacking mixed. It has no taste, which'^eems 

 very strange, that a fuliginous exudation should be insipid. 



She never had the menses, is thin, but healthful ; the blackness appears no 

 where but in the prominent part of her face. 



A clergyman communicated the following occurrence to me, viz. A gentle- 

 man's servant having killed a ewe, which was thought fat, and taking out the 

 bowels, found a very unusual and monstrous lump of fat, proceeding like a wen 

 from the middle of the omentum. The clergyman having cut it open, found 

 inclosed a lamb, of the same parts and dimensions as others of that kind. The 

 question was, how it came there ? and how it was nourished ? I soon appre- 

 hended what it was that seemed so strange and unaccountable, having 30 

 years since been shown the like, found in a bitch, by a surgeon in Oxford ; 

 and from that time observed and considered all of that nature which have oc- 

 curred to me in books or otherwise ; and hence concluded, that the lamb was 

 not conceived in the womb, but in one of the Fallopian tubes ; where growing 

 too large to be contained, it either broke out into the place where it was found, 

 or slipped back towards the upper orifice, and through it into the ewe's belly ; 

 that afterwards, assisted by the prone and inclining jx)sture of the sheep's body, it 

 slipped forward to the omentum, and was there nourished in the usual way, viz«
