Would like to subscribe to English edition of Weismann.

References to Fritz Müller’s papers relevant to Weismann’s Studien [in Kosmos (Aug, Sept, and Oct 1877)].

Will proof-read his preface to Weismann’s Studien.

RM’s application to the Royal Society.

CD happy to lend Weismann’s pamphlet to RM.
