Letter from Sir Oliver [Joseph] Lodge, FRS, Mariemont, Eogbaston, to James Mackenzie Davidson Thanks Mackenzie Davidson for sending his stereoscope, however, notes that he cannot get its arm and hook anything like it was when he saw it in Mackenzie Davidson's room. Also asks Mackenzie Davidson whether he has a slide of any patient whose tissue he is building up with x-rays. 13 February 1904
