may be made use of without delay, or attendance to accompanying symptoms, at 

 least till they render themselves more conspicuous and certain than he had hitherto 

 been able to find them ; and as the operation is not at all dangerous, it neither

XXXVI. A Chemical Essay on the Action of Quicklime on the Volatile Alka- 

 line Salt. By I. A. Schlosser, M. D. of Utrecht, p. 222. 



As the true nature of quicklime was unknown at the date (1755*) of this 

 essay, the theory which Dr. S. has offered concerning the different phenomena 

 produced by the action of burnt lime on the volatile alkali, is wholly erroneous. 

 It is therefore deemed unnecessary to be more particular in the notice of this 

 paper. 



XXXVII. An Account of a very remarkable Case of a Boy, who, nottoith- 

 standing that a considerable Part of his Intestines was forced out by the Fall 

 of a Cart upon him, and afterwards cut off, recovered, and continued well. 

 By Mr. John Needham. p. 238. 



On the 3d of January 1755, Mr. N. was called to the son of Lancelot Watts 

 (a day-labourer, living at Brunsted) a servant boy to Mr. Pile, a farmer at West- 

 wick, near North-Walsham, Norfolk, aged 13 years. He was overturned in a 

 cart, and thrown flat on his face, with the round, or edge of one side of the 

 cart, bottom upwards, whelmed across his loins, the upper part of the body 

 lying beyond the wheel at right angles. In this helpless condition he continued 

 some time, and was found with a very large portion of the intestines forced out 

 at the anus, with part of the mesentery, and some loose pieces of fat, which 

 Mr. N. took to be part of the omentum, hanging down below the hams, double, 

 like the reins of a bridle, very much distended and inflamed. He had a conti- 

 nual nausea, and violent retchings to vomit, and threw up every thing he took. 

 The pain of the stomach and bowels was exquisite, attended with convulsions; 

 his pulse low and quick; and frequently he fell into cold sweats. After using an 

 emollient and spirituous fomentation, Mr. N. reduced the parts, though to no 

 purpose; the vomiting immediately returned, and forced them out again. Next 

 day the fever increased, the nausea and retchings to vomit continued, the parts 

 appeared livid and black, with all the signs of a mortification. On the 3d day 

 the mortification increasing, he cut off the intestine, with the mesentery, close 



• It was about a year after the above date that Dr. Black's experiments on quick-lime, which de- 

 monstrated so cleariy the difference between mild and caustic calcareous earth, mild and caustic 

 alkalis, &c. and which laid open so vast a field of discovery in gaseous chemistry, were first commu- 

 nicated to the world.
