Letter to James Cossar Ewart from John Walter Gregory, 29 January 1929

 Item
Identifier: Coll-14/9/35/3
Scope and Contents

Gregory writes that he is interested in the photographs Ewart sent him. He imagines that hairs and scales probably arose from different types of papillae and that the hair developed between the scales and gradually replaced them as the animals required more thermal protection.
