Fig. 64. Tarsius spectrum. Cortical areas of the brain. This figure is based 

 upon a sketch by Professor Elliot Smith. The numbers have been added tentatively 

 by the writer. They provide for the comparison of the brain of Tarsius with that 

 of the Lemur (Fig. 46) and with other brains described in the sequel. Attention is 

 directed especially to the areas marked 1, 4 and 17 respectively, corresponding to 

 those named by Brodmann as follows : 



No. 1. Area post-centralis. 

 No. 4. Area giganto-pyramidalis. 

 No. 17. Area striata. "(Elliot Smith.)

 Professor Elliot Smith). These brains of Insectivora, together with that of Tarsius 

 (Fig. 64), serve well to illustrate the evolution of the cortical areas, and the general 

 form of the brain.
