Description | 'I shall be glad to know whether the illustrations of colour photography you have been good enough to consent to show at our Soiree lend themselves to a lantern demonstration and, if so, whether you would be inclined to let your exhibit take the form of a short exposition in the lecture room in the course of the evening. Believe me, Very truly yours, Robt Harrison Asst. Sec. R. S. [Assistant Secretary, Royal Society]'. |
