Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to Thomas Barclay, Esq., Amoy [Ximen], China Regrets to inform there are no separate copies of papers read before 1875. States there is a large stock of the volume from 1871, which contains Thomas Barclay's article, but is expensively priced at £2.10. Suggests having typewritten copies as the article is only a few pages. [The paper is 'Measurements of specific inductive capacity of dielectrics, in the Physical Laboratory of the University of Glasgow']. 29 October 1928
