According to John Gwyn Jeffreys’ book [British conchology (1862–9)] shell is Sphaerium corneum, a synonym of Cyclas cornea.

CD regrets that he feels large parts of Krause’s essay [on Erasmus Darwin] must be omitted. Gives his criticisms and his plan for condensed publication of his own article, with only parts of EK’s. If EK is unwilling to change, CD will publish his article privately. It is manifest that EK can publish his essay in its extended form in Germany if he wishes to do so.

Glad to receive the German edition of Erasmus Darwin. Hopes sales will be good. Favourable review has appeared in the United States, in the Nation.

Profit on Erasmus Darwin is £9 15s 5d. Sends cheque. 218 copies remain unsold.

All his advisers agree that CD ought not to take notice of Butler’s attack.

F. M. Balfour has offered to translate EK’s reply to Butler and to send it to Nature. [The letter was published in Nature 23 (1881): 288.]

Asks further questions about shell attached to beetle’s leg.

Thanks CD for Descent

and for his praise of Cosmic philosophy [1874].
