Has received [read?] CB’s two works [Chamois hunting in the mountains of Bavaria (2d ed., 1860) and Forest creatures (1871)] and has made use of them in his present book [Descent].

CB’s descriptions of the Tyrol make CD long to be "strong and young again to ramble over the mountains".

Thanks CB for Transylvania [1865].

CD’s health has declined steadily. He must now be content to read about nature as described by CB and others.
