Copy letter from Herbert Rix, to Professor William Crawford Williamson, Fellow of the Royal Society The Soirée Committee are anxious to have a selection from the sections which Williamson showed at the May Soirée repeated at the June Soirée. They will not be able to make quite so much room on this second occasion but if Williamson could show say half a dozen microscopes either with new specimens or those used before, the Committee would be much obliged. If Williamson will hire the microscopes that will suit his purpose the bill may be sent to Rix. 19 May 1893
