presents a greater diversity of conditions than that of the latter, rendering it a fit habi- 

 tation for a greater variety of life. Such a view is in no way inconsistent with the 

 supposition that the number of species per unit area is as great, or even greater, in

It is true that an insignificant proportion, numerically considered, of those who fre-

 systematic zoology or botany. But every working biologist, whatever his specialty,
