i8 PATHOLOGICAL OBSERVATIONS 



brownifli matter in the bottom, on touching of which with the 

 knife, I difcovered Itony concretions, which were taken out and 

 waflied. Several of them broke into fand on the flighteft 

 touch ; but four or five of them, each about the fixth of an 

 inch in length and breadth, and a little thicker than the fhell 

 of an egg, I faved, and afterwards gave to Dr Monro, who was 

 not then prefent. 



Case 2. William C. about forty-five, of a corpulent ha- 

 bit, was, for feveral years, fubjedl to epileptic fits, which com- 

 monly returned every three or four weeks, and any irregularity 

 in eating or drinking would immediately bring them on ; but 

 when cautious, living fparingly, and taking fome laxative, he 

 •was often free from them for four or five months. 



The fits always came on with convulfive motions in the right 

 arm and leg, which, in a few minutes, were fucceeded by ftu- 

 por, in which he continued above half an hour. In November 

 1775, he received a ftroke on his head, which brought him to 

 the ground ; was inftantly feized with one of the fits ; and, in 

 twenty-four hours, had ten or twelve of them, in all of which 

 the only parts convulfed were the right arm and leg ; the fits 

 became more frequent, a total ftupor came on, and he died 

 fourteen days after. 



On opening his head, on the left hemifphere, immediately 

 under the coronal future, and an inch from the falx, the dura 

 mater adhered to the brain, for about the fize of a fhilling, and 

 was fo much thickened and hardened as to be in a cartilaginous 

 ftate ; the brain, for the fize of a large walnut, was much 

 hardened, and the under part of it adhered flightly to the falx ; 

 on the outer fide of this hardnefs, on that fide furthefl from the 

 falx, and in the middle of the fubflance of the cerebrum, there 

 was about an ounce and a half of extravafated blood, which 

 was foft, and of a black colour. .
