VOL. XXIII.] PHILOSOPHICAL TRANSACTIONS. 5 



tighten the sutures, which had become loose. The dressing and bandages were 

 afterwards laid aside, and in the course of three weeks the wound was healed 

 merely by the dog's licking it. 



After keeping the dog for some weeks, during which time he was perfectly 

 healthy and lively, he was hanged and opened ; when the part of the intestine 

 where the suture had been made was found in the left hypochondrium (at a con- 

 siderable distance from the external wound which was made in the right hypo- 

 gastrium) firmly united to the peritoneum, see fig. f, and enlarged into the 

 form of a sac, ddd. The omentum, g, also adhered to it, and there were 

 moreover adhesions of the intestines, ** ee, in several places. In order to exa- 

 mine the cicatrix on the inside, they cut open the intestine longitudinally, when 

 it appeared that the lips of the wound had formed adhesions on one side to the 

 peritonaeum, and on the other to the adjacent intestines ; so that the external 

 coats of these last constituted the internal surface or side of the gut that was 

 wounded, forming a continuation of the intestinal tube, and thus affording a 

 convenient passage for the food. 



Mr. S. then proceeds to notice similar experiments made on brutes by other 

 persons, viz. by Brunner, (see the preface to his Experimenta Nova circa Pan- 

 creas), who made a wound I4- inch long in the small intestine of a dog, after 

 which the animal, though with difficulty, recovered ; and by Mr. Cowper, see 

 N° 208 of these Transactions : but in neither of these instances was a portion 

 of the gut cut away. Lastly, Mr. S. refers, as connected with the subject, to 

 Dr. Wallis's account of a horse, that staked himself in the stomach in leaping 

 over a fence, inserted in N° 219 of the same Transactions. 



Although there is a great difference (Mr. S. remarks) between the condition 

 of the intestines in man and brutes, yet he infers that the above-mentioned 

 successful experiments upon dogs, may serve as an encouragement to surgeons to 

 sew up wounds of the intestines, especially of the larger intestines, whenever 

 those parts become wounded in the human subject. 



The figure which accompanies this account was drawn by Mr. Cowper.
