PROFILE VIEW OF THE SAME THREE PIN BROTHERS 



Some Microcephalics learn to read and write, but these three boys never could be taught to 

 count. Two of them had a mental age of three, the other of four years. On the theory that tne 

 condition is caused by too early ossification of the sutures and fontanels, operations have been 

 attempted to enlarge the cranial cavity, but they never resulted m any mcreased development ot 

 the brain. (Fig. 18.)
