[Thomas Davidson, Scottish palaeontologist.] Autograph Letter Signed ('Thos Davidson') to S. P. Woodward of the British Museum Department of Geology, notifying him of various developments in the field.

A good letter, breathing enthusiasm for his field of study. 3pp, 12mo. Bifolium. In good condition, lightly aged. Folded twice. He begins by stating that he will not be calling at the Museum that week, but writes to 'drop you a line to say that I have received a very long letter from Mr [Suett?] full of details regarding Ilrigocephalus etc and in which he mentions that he can drown you with notes on Rudists'. He also refers to 'a good paper by V. Hauren on the Structure etc of Caprina Partschi' ('a synonym of Cap. Paradoxa Matheron'). He announces: 'I leave positively for Belgium among the first days of next week, but will call on you o Monday at the Museum and bring with me the Calceoles and the descriptions of the new Terebratula of Carney in case you should wish to take a note or two from them to insert into Mr. Grays Catalogue as I will not be in London again before the beginning or end of the first week of June.' He hopes on his return 'to be able to bring all the materials to finish your notes for the part on Brachiopods in your interesting little Manual'.
