Has just received copy of CD’s work [Descent].

Can corroborate artificial compression of skull practised by Indians.

May have to modify his earlier published opinions on CD’s views.

Thanks for new book [Descent].

Thanks for Descent; will forward any information he has after he has studied it.

Instance of inequality in left and right anal appendices of caddis-fly.

A second edition [issue] of Descent may be needed in short time; preparations should be made, and corrections sent to Clowes. Wallace, Mivart, and F. P. Cobbe have been sent copies of both volumes.

Thanks CD for sending his book [Descent].
