Journal of a walking tour in Merionethshire and Caernarfonshire made in August and September 1884 by the geologist Dr Edward Greenly, later of Llandegfan, Anglesey, and described by him in his memoirs, A Hand through Time, 2 vols (London, 1938), I, 104-7. The journal includes four maps and is illustrated throughout with pen-and-ink drawings, the one on p. 194 of the journal, entitled 'Llyn-y-Gader', being reproduced as plate XVI in A Hand Through Time. A few annotations and corrections were added by Greenly in 1935 and 1939.
