Letter to James Cossar Ewart from John Walter Gregory, 29 December 1927
Gregory writes that the lower jaw of a horse has been discovered in the upper drifts filling the pre-glacial valley of the Clyde at Lanark. He suspects that it dates from around the Early Neolithic period. He asks Ewart to look at the specimen and write a short note on it for inclusion in the Hunterian Museum glacial vertebrate fossils.
Letter to James Cossar Ewart from John Walter Gregory, 03 February 1928
Gregory enquires after Ewart's note on the horse for the Museum catalogue, as it is ready to go to print.
Letter to James Cossar Ewart from John Walter Gregory, 08 February 1928
Gregory writes that he has provisionally inserted the bed in a tabular classification as Neolithic. He believes it must be post-glacial, as it represents the silting up of valleys which were excavated at the end of glacial times, but the horse jaw is the only fossil evidence of this.
Letter to James Cossar Ewart from John Walter Gregory, 29 January 1929
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.
Letter to James Cossar Ewart from John Walter Gregory (incomplete), 14 January 1929
Gregory provides information on what he believes to be the causes of evolution of mammals from reptiles.
The latter part of the letter, incuding the author's signature, is not present.
