4 PHILOSOPHICAL TRANSACTIONS. [aNNO J 703. 



phurs, vitriols, mercuries, simple precipitate or sublimate, and such sort of cor- 

 rosive and penetrating medicines. These being infallibly powerful to kill the 

 vermin lodged in the cavities of the skin, which scratching will never do, partly 

 by reason of their hardness, and partly because they are so minute as scarcely to 

 be found by the nails. 



Neither do inward medicines perform any real service in this case, it being 

 always necessary, after a tedious use of these, to have recourse to those external 

 ones already mentioned. And if in practice we often experience that this disease, 

 when we think it quite cured by unction, yet in a short time returns again ; 

 this is not surprising, since though the ointment may have killed all the living 

 creatures, yet it may not probably have destroyed all their eggs, laid as it were 

 in the nests of the skin, from which they may afterwards breed again and renew 

 the distemper. And on this account, it is very advisable, after the cure is 

 once performed, still to continue the anointing for a day or two more, which it 

 is the easier to do, beamse these liniments may be made agreeable enough, and 

 of a good smell, as particularly is that compounded of the ointment of orange 

 flowers or roses, and a small quantity of red praecipitate. 



An Account of the successful Excision of a Portion of a Dogs Intestine. By 

 Mr, John Shipton, Surgeon. Abridged from the Latin. N° 283, p. 1299. 



After remarking that wounds of the intestines have always been considered as 

 mortal (in the human subject) by the best surgical writers, both ancient* and 

 modern,-^- with the exception of Barbette ;:{: Mr. Shipton proceeds to the rela- 

 tion of an experiment which shows that such wounds do not always prove fatal 

 in the canine race. In these experiments he was assisted by Mr. Pleahill and 

 Mr. Dobyns. 



Having tied down a dog in the usual manner, and made a large incision into 

 the animal's abdomen, they drew out the nearest portion of the ileum ; and 

 after securing the mesaraic vessels by ligatures, they snipped the intestine across 

 in two places with scissars, and cut out a considerable portion (portionem duos 

 circiter digitos longam) ; they then sewed up the wounded gut with the glover's 

 suture, and the wound of the abdomen with the interrupted suture, after which 

 they applied a plaster and bandage. When the dog was set at liberty he tottered 

 and reeled about in attempting to walk, and appeared to be extremely weak- 

 ened; the same night he vomited twice. After some days it became necessary to
