Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to R. F. Young, Esq., The Athenaeum, SW1 Informs that a copy of 'Via Lucis' by Comenius can be found in the 1840 catalogue but the Library no longer has a copy. Explains it might have been weeded out along with other 'non-Scientific books' around 1860 or after. Expresses interest in R. F. Young's thought of the 'Invisible College' being in existence as early as 1645. 10 February 1928
