Will ask about Ernst Krause.
Wants FD to find out what sort of man Ernst Krause is.

Requesting parts or volume of the Philosophical Transactions due to him.
Intends to publish a translation of Ernst Krause’s essay on Dr Erasmus Darwin, with a prefatory notice by himself. Asks JM to decide whether to publish it on commission or on usual two-thirds profit terms. CD incapable of judging chance of its selling.
Thanks for FD’s letter describing microscopic work under experienced supervision.
Is glad to hear of C. E. Stahl’s objection to treating plants as mere machines.
Pleased that J. von Sachs has yielded on growth.
Perhaps Stahl will recognise whether the case of the silver fir is the same as that referred to in the German account [see 12074b].
CD has finished the first draft of his essay on Erasmus Darwin’s life and is "heartily sick of the job".
Thanks for reply to query. Asked E. Haeckel same question and his answer agreed with CD’s. Haeckel disbelieves in the supernatural. What does CD think?
Is well disposed toward publishing Krause’s essay on Dr Erasmus Darwin, particularly if CD undertakes to fill up its gaps. He thinks ED’s reputation is increasing.
Does not feel competent to judge on matters of measurement. R. B. Litchfield to look into case.
Thanks for letter of 27 April (Julian calendar; 9 May Gregorian calendar), and promised gift of wheat varieties. Will probably send them to Alexander Stephen Wilson.
Wants to republish Fritz Müller’s paper ["Ituna and Thyridia", Kosmos 5 (1879): 100–8] in Proceedings of the Entomological Society. [Thyridita!?]

Has been writing life of Erasmus Darwin.
Wants plants with heliotropic aerial roots. Has proved root apex governs nature of flexure in upper part of root.
Has read Dallas’ translation of first part of EK’s essay [on Erasmus Darwin]. Has sent his MS to printer. Is perplexed by duplication. Thinks EK’s essay is better than his. Wishes he had sent all his material to him for a single biography. Best plan may be for EK to incorporate whatever he thinks useful in CD’s material.
NvM’s questions cannot be answered fully. "Science has nothing to do with Christ, except in so far as the habit of scientific research makes a man cautious in admitting evidence. For myself, I do not believe that there has ever been any Revelation."
Unable to accept invitation.
Looked at leaves and saw no sign that animal matter was absorbed. Believes insects were caught only accidentally.
