Letter from H[enry] B[rougham] Guppy, 17 Woodlane, Falmouth, to [Henry Bowman Brady] Asks Brady to send him his opinions on the soft deposits and the chalk-like coral rock, as regards their depth, age, etc, as Guppy is preparing geological notes for the press. Asks Brady however not to inconvenience himself, as half a dozen lines on the matter will do. 22 February 1887
