30 HEAD. 



.B. Now we can understand why what always 

 seems to be so dangerous should be attended with no 

 more injury, the falling of boys upon the ice, as if 

 they would sometimes beat their heads in. It is in- 

 deed a beautiful fact, that the part of our head which 

 cannot have the protection of our hands, when we

 are the thinnest part of the box, are placed directly 

 over the shoulders, which secure them in case of a 

 fall ; and, besides, are a little flattened in within the 

 general circle of the head, which preserves them still 

 further from any blow ; and what is again remarkable,

 matter in the whole body. " Generally it is observ- 

 able," says Dr. Bell, " of the whole structure of the 

 head, that those parts which would be most apt to 

 strike the ground when a man falls are the strongest."

 pressure of the blood.

T. Apoplexy, the most fatal of all disorders in

 known to be brought on by persons whose vessels
