near four inches one way, and three the other, and tied the blood veiTels. 
The fracture extended acrofs the os bregmatis, from the fagittal future to 
the temporal bone; that part next the os frontis was deprefled equal to 
its thicknels, and a great deal of cxtravalated blood and matter lay under 
the other pai t of the lame bone. I made two perforations with the tre¬ 
phine, dole to the fradure, that I might raife it up lleadily through both, 
and have more room for the extravafated blood to difeharge: And ten 
days after the former operation, the apertures being almoll filled up with 
the callous, I was obliged to make another perforation, to difeharge the 
matter more freely; for during a month, it ran through all the drelfings 
down her face, twice every day, and was exceedingly foetid; and for the 
Ipace of five months the matter decreafed very little in quantity, but
