Describes case of two varieties of Russian wheat, the kubanka (or White Turkish) and the saxonka, which grow side by side with no intermediate varieties. As kubanka gradually yields place to saxonka, thinks an unusual tendency to jumping variation [saltation] operates; suggests CD urge some young botanist to investigate [see ML 2: 419–22].

On publishing details for various CD books.

Has no corrections for new issue of Descent [2d ed.].

Questions amount of cheque for profits.

Thanks for accounts which make everything intelligible to him. Since he was glad to have Orchids published at one-half of profits for himself, he believes it would be very shabby to accept JM’s new offer of two-thirds profits. Thinks it would be fairer to both to change to JM’s usual practice with authors [i.e., annual statements of sales, payments based on them, and final accounting when all copies have been sold].

Encloses a cheque for £11.19.9. Will transmit £7.9.4 to Fritz Müller. Thanks for account of the sale of his books, which appears to be in a "lamentable state".

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.

Though not sanguine about sale [of Erasmus Darwin] it seems fair that if over 1500 copies are sold he should receive two-thirds profit. If JM does not agree, he would prefer publishing on commission or asking Macmillan if they will give him larger profits.
