Hist.

Review," January 1865, page 139.

A notice by "J.L." (probably Lord Avebury) on Walsh's paper "On Dimorphism in the Hymenopterous Genus Cynips," in the "Proc.
Entomolog.Soc.of Philadelphia," March, 1864.): whether the notice will be favourable, I do not know, but anyhow it will call attention to your views...
As you allude in your paper to the believers in change of species, you will be glad to hear that very many of the very best men are coming round in Germany.

I have lately heard of Hackel, Gegenbauer, F.Muller, Leuckart, Claparede, Alex.

Braun, Schleiden, etc.
