Thanks CD for copy of Expression.

Reports on a monkey that throws things when "angry".

Explains how natives count to more than four; CD incorrect on this point.

Sends photographs of blacks.

Cicadas out in force.

If decapod does not pass through zoea stage, is this acceleration? If hypothetical adult retained zoea characters, would this be retardation? Believes obliteration of growth stages frequently due to natural selection. Most interesting points in AH’s letter deal with senile characters. CD attributes them to laws of growth not selection. Explains degraded characters as result of readaptation to simpler conditions. Believes no innate tendency to progressive development exists.

Hopes AH visits F. Hilgendorf’s famous deposit [at Steinheim]. A. Weismann [Einfluss der Isolierung (1872)] makes good use of Hilgendorf’s observations.

First edition of Expression nearly exhausted. Asks CD to send corrections to the printer for another issue, Murray thinks, of 2000.

Drosera filiformis captures only small insects [but see 8989].
