440 PHILOSOPHICAL TRANSACTIONS. [aNNO 1740. 



appeared, from the eyebrow all over the left side of his head ; and after having 

 shaved him, Mr. C. was surprised to feel, with his fingers, so many rugged 

 splinters of the cranium, confusedly depressed through the dura and pia mater, 

 into the substance of the brain ; the extremities of which appearing above the 

 dura mater, he extracted to the number of 5, besides several other bits and 

 small pieces ; in taking out the last splinter, being part of the superior and in- 

 terior part of the orbit, containing some of the basis and inferior part of the 

 OS frontis, joining by the sutura transversalis to the superior part of the os 

 malae, with part of the said suture and the upper extremity of the sphenoides, 

 almost to the lower end of the sutura coronalis and squamosa; this splinter was, 

 the major part of it, depressed under the superior part of the great depression 

 of the OS frontis, on extracting of which', 2 pieces of the substance of the 

 brain, with clotted blood, came out with it, one as large as a kidney bean, 

 and the other as large as a pea ; at which time the patient fainting and vomit- 

 ing, brought up most of what was contained in his stomach, mixed with bilious 

 and bloody matter. 



The dura mater was very much contused, lacerated, and bare, upwards of 3-J- 

 inches in length, and at one end 1-l inch over, the remainder about ] inch, 

 and the edges rugged; from the upper part of the fracture, there was a depres- 

 sion of the OS frontis, which reached up to the sutura sagittalis, near the co- 

 ronal suture; one part of the cranium lapped over the other, which he sawed 

 off on the 3d or 4th day, it being an inch long, and occasioned a great deal of 

 trouble, before it could be raised up with the elevator, the inferior part of the 

 fracture being so thin and weak; the depressed part terminated in a long fissure 

 about an inch behind the coronal suture in the bregma. The scalp was so much 

 contused and lacerated, that the next day it began to mortify, which obliged 

 him to lay bare all that side of the coronal, and the greatest part of tlie 

 bregma, home to the lamboid suture, from the upper part of his head down 

 to his ear. 



The dura and pia mater were very livid, and insensible to the touch, except 

 those parts where the brain was wounded, in the dressing of which the motion 

 or pulsation of the brain was very strong, and sometimes to that degree, that 

 it would rise considerably above the surface of the cranium; which obliged him 

 to keep it down sometimes more than 2 or 3 minutes with his fingers, and a 

 large and thick sindon dipped in a warm detergent lotion, before it would cease, 

 introducing it between the dura mater and the edges of the fracture. 



The upper eyelid in a week's time imposthumated; and formed a tumour as 

 large as a hen's egg, which he opened, and kept it so a considerable time, be- 

 cause there was a plentiful discharge of matter from it, which was at first very
