Note 39 — ON STEPPES AND DESERTS.
Henry G. (Henry George) Bohn translation
p. 16.—“The humid clay soil is seen to rise slowly in a broad flake.”
Drought produces the same phenomena in animals and plants as the abstraction of heat. During the dry season many tropical plants lose their leaves. The crocodile and other amphibious animals conceal themselves in the mud and lie apparently dead, like animals in cold regions who are thrown into a state of hybernation.[HC]
