The softest and least dense part of the skull

This area [bregma] where the sutures just mentioned join is thought to be the softest and least dense part of the entire skull: this is the part [fonticulus anterior] 97 that in newborn infants is still membranous, and feels like fresh cheese; it moves visibly when babies chew and breathe. Because this spot, called Zeudech by the Arabs, is the thinnest among the unfleshed parts of the head, and the sutures nowhere hold more loosely, doctors apply to this point what is commonly called cautery, either with glowing gold, or iron, or whatever caustic medication they think appropriate to the condition (unsafe though this is). 98 In ourselves, the place is readily guessed with the tip of the middle finger if one places the beginning of the wrist between the brows or the top of the nose 99 and presses the middle finger straight down upon the top of the head.
