for the purposes in question. It is difficult to see the over- 

 powering necessity for running off the rain even in tropical 

 countries, and certainly vast numbers of animals even in the 

 moist climates of the Miocene age cannot have spent so large a 

 portion of their lives in torrential rain as to make any direc- 

 tion of hair adapted to such conditions a necessity of their 

 structure. In illustration of which I would adduce Eodents, 

 and burrowing animals in general, where the effects of pressure 

 would be so strongly operative. 



The most notable regions of the human body where arrange- 

 ments which I have termed 'peculiarities, for the sake of con- 

 venience, will now be considered. 



1. Frontal region. — Here a slope of hair is found which 

 results from a coalescence of the streams belonging to the 

 scalp and inter-orbital region. Over the frontal region the 



stream passes to each side in a curving direction to the tem- 

 poral regions. Towards the orbits it is lost in the eyebrows, 

 and towards the scalp, close to the middle line mainly, it passes 

 in a course parallel to the median plane to the edge of the 

 scalp, where it is lost in the hair of that region. Towards the 

 frontal eminences the direction has curved so as to point to the 

 temporal regions. The only peculiarity in this region is the
