Letter to James Cossar Ewart from Frederick Webb Headley, 03 October [1903]

Identifier: Coll-14/9/9/108

Scope and Contents

Headley informs Ewart that the Fabian Society have asked him to lecture on the bearing of Weismannism on modern social questions. He challenges Ewart's statement that enfeeblement in pigeons can be traced to an illness in the parents at the time of conception as being more allied to Lamarckism. Headley suggests that this is more likely to be due to lack of food supply to the egg.

The date on the letter does not include a year, but another hand has noted '[1903?]'

Weismannism is the theory that all inheritable characteristics are transmitted by the reproductive cells and that characteristics acquired during the lifetime of the organism are not inherited; Lamarckism states that an organism can pass on characteristics that it acquired during its lifetime to its offspring.
