After the integuments were removed, the top of the cranium appeared soft and 

 membranous. The extent of the membrane, from one temple to the other, 

 was 8 inches, between the parietal bones 3^- ; from the os frontis to the os 

 occipitis, 12. In the middle, just on the crown, lay a bone (in some places a 

 little cartilaginous) 3 inches long, and 1 broad, joined to the membranes on 

 every side, of the same thickness with the rest of the upper part of the cranium 

 that was bony, which was extremely thin every where, and the laminae lay so 

 close, that in many places no diploe could be discerned. The membrane was as 

 thin as the pericranium, which yet was easily divided from it. None of the 

 sutures were entirely closed ; those of the upper jaw were very loose. In the 

 temporal and lambdoidal sutures there was a vast number of the triquetra Wor- 

 miana, all which had so many distinct sutures. 



Upon piercing the dura mater, a great quantity of water flowed out ; which 

 lay as well between the dura mater and the pia as in the ventricles of the brain : 

 the liquor was thin, pale, and insipid, and amounted to 5 quarts. The dura 

 mater was firm and entire, of its usual thickness, and stuck very close, as well 

 to the membranous as to the bony parts of the cranium. All its processes and 

 sinuses were singular, the 4lli sinus somewhat larger than ordinary. A very
