WE regret to announce the death of Mr. Francis A. Towle on Jan. 10, at the age of fifty-seven years. He will be remembered by a large number of scientific workers and others through his official connexion with the Royal Society, of which he had been assistant secretary since 1921, while for the preceding twenty years he had been clerk to the Government Grant Committee. Mr. Towle's earlier life was spent in Birmingham. His keen, incisive manner will be missed by many fellows of the Society that he served so zealously during a period of active expansion in many directions. Outside his work, he showed great interest and skill in all kinds of mechanism, and sometimes regretted he had not devoted himself to engineering. For example, he built model locomotives that ran on miniature railway systems of his own construction, and installed electric light plant in at least one country-house. Mr. Towle was also an enthusiastic photographer, and will certainly be missed in the Camera Club.
