The letter from H. G. A. (Harry Gidney Aldis) is dated 2 February 1913, Candlemas day, on paper embossed with Grennan, Grantchester Meadows, Cambridge. It is written to 'My dear Johnston' . The letter refers to no further word 'heard from the Astronomer Royal about the incunabula which he is so yearning to send to Cambridge for possible identification'. The letter also talks about illness in the library and about how work offers 'much arrears to mop up before we can venture to start on fifteeners' (incunabula). It goes on to mention how there 'is no photograph or other illustration of the Laing MS of the Philobiblon that I know of' . Aldis has also enclosed 'a rubbing of the binding [...] It is a XVth cent manuscript and the binding is alike on both sides.
The letter offers an archival history of the manuscript 'as related by E.G.D.' (possibly E. Gordon Duff). Apparently it had been 'bought by Laing (through Rev. Wm Stevens) in 1839 from J. L. C. Jacob of Rotterdam for 42 francs'.
The letter was placed inside a copy of Notices of David Laing : to which is added a chronological list of the various publications which were issued under his editorial superintendence from the year M.DCCC.XV. to the year M.DCCC.LXVIII inclusive, by Thomas George Stevenson, 1878, along with a Letter from Edward Gordon Duff (1863-1924) to Mr. Johnston which is now at E2010.34.
The letter is accompanied by the rubbing mentioned above.
