Physiography

Physiography, a term formerly used of a branch of mineralogy, was adopted by Professor Huxley as a convenient name for an exposition of the principles that underlie physical geography, and including the elements of physical science. Physiography is thus understood to involve a compendious discussion of gravitation, heat, the composition of the crust of the earth, the movements of the sea, the phenomena of the atmosphere, and many cognate subjects, treated in this work under separate heads.
