Inquires about the effect of turf covering on the rate of disintegration of rock.
Has completed a memoir on the Aymara Indians of Bolivia [J. Ethnol. Soc. n.s. 2 (1870): 193–305] and is going to lecture on them.
Believes he has data relevant to CD’s work on man.
Would much like CD to contribute a note for insertion after his paper on Aymara Indians.
Thanks for copy of Descent.
