Returns Smith the curious Nepalese plant as he does not preserve exotics. Smith and he agree on use of "shall" and "will" and encloses copy of home instruction for use [not extant]. Encloses copy of letter he sent to [Thomas] Rackett [extant] describing his childhood sighting of red viper near Newbury, [Berkshire], and suggests name 'Coluber chersea', to be read as response to Rackett's "Linnean Transactions" paper.

Received seeds of Bergamont mint from Peru from his son. They have great prospect of fruit; used oiled paper frames to save from cold on open wall. Attempting to have green melons for 4 June anniversary but fears will be too late. Gave away cucumbers yesterday.
