bladders came from her stomach, and urged the following reasons for her opi- 

 nion; first, had they been originally in the bowels, in all likelihood the purges, 

 of which she took many in the jaundice, would, as she said, have carried them 

 off much sooner. Secondly, from the almost constant pain of her stomach, 

 and frequent inclination to vomit, ever since her fever, to the time of discharg- 

 ing the bladders. Thirdly, from the rawness and soreness of her stomach after 

 the bladders came off. This was her opinion, and these her reasons for it; and 

 indeed I think they may be esteemed so far of force, as to prove, that some, 

 and perhaps a great number of these bladders came from her stomach. 



There was no appearance in any one of these bladders of such an order of 

 parts, or organs, as showed them to be insects; nor upon examination was there 

 any animal discerned in the liquor contained in them. Indeed, these observa- 

 tions were made only by the naked eye. 



The medicines given, after I was called in, were chiefly of the vulnerary 

 and digestive kinds; that which did her most service, but it was after the 

 bladders were come off^ was a tincture of myrrh and gentian, in large and fre- 

 quent doses, and with a proper vehicle; under the use of this slight but advan- 

 tageous medicine, from a very weak condition, she recovered an appetite, &c. 

 and is now perfectly well. 



Abstract of a Letter from Mr. John Thorpe, M.A. to Dr. Hans Sloane. S.R.S, 

 concerning Worms in the Heads of Sheep, &c. Dated Oxford, July 24, 1704. 

 N°295, p. 1800. 



With this you receive the delineation of a worm,* fig. 1, pi. 7, found in 

 dissecting the head of a sheep, in the cells formed between the laminae of the 

 OS frontis; it is an apode, and seems to be a species of the eulae, though much 

 different from the common sort breeding in putrid flesh. It is every where of 

 a fair pale colour, excepting its tail, which ends a little obliquely in a plane, on 

 which are impressed two remarkable black spots. Besides two small white cor-, 

 niculae, its head is armed with a pair of black, sharp, and crooked forcipes, 

 which, in contracting and extending its body, it draws in, and puts out at plea- 

 sure; with these, in creeping, it takes hold of the surface of the body on which 

 it moves, and draws itself forward on pretty large, protuberant, and somewhat 

 flattish toruli, fewer in number than those on its back, as in fig. 2; which alter- 

 nately swelled and relaxed, seem instrumental to its motion, and supply the place 



* Seemingly the larva of some insect, perhaps the larva of the oestrus ovis ? The vertigo or giddi- 

 ness of sheep is ascribed to the presence of a diflFerent animal breeding in the substance of the brain, 

 viz. to the hydatis multiceps.
