Copy letter from William Bate Hardy, Secretary of the Royal Society; to J. H. Parsons Esquire; 54 Queene Anne Street, W.l. Informs Mr. J. H. Parsons that Mrs Harris' application raises some difficulty. Notes that some time ago he asked Professor [Frederick Gowland] Hopkins to put one of his researchers on to the chemistry of the lens, and therefore that he will consult with Professor Hopkins before taking any action with regard to Mrs. Harris. 19 November 1920
