Letter from Margaret Ogilvie, the Department of Ophthalmology, the University of Oxford, to James Mackenzie Davidson Asks if Mackenzie Davidson will consent to giving a lecture on X-ray localisation during the summer term at Oxford. Notes that, at present, she can only guarantee a fee of £2:2:0 and that it is hoped the lecture will form part of a series of lectures to be published in book form. [Note on top left corner of the letter in Mackenzie Davidson's hand: 'accepted'] January 1911
