Abstract
I TAKE in NATURE in parts. Your part for May last has just reached me in Calcutta, and is somewhat rich on the question of the thickness of the earth's crust; for three of its four numbers contain letters on that subject. First, my letter to you, p. 28; two critiques upon it from “A. J. M.” and Mr. Green, p. 45; and a third from Mr. David Forbes, p. 65.
