His botanising is limited to the "rude mountains" of his locale and mists have made the season unfavourable to Highland botanists. Will pass through London on his way to East Indies this summer. Studying Persian in Edinburgh in a month; intends to send Smith "some small fruit of [his] botanical labours". Hopes Smith has received a copy of his thesis. Smith's opinion of 'Lichen gelidus' well founded; hopes to send specimens but difficult to procure. The moss he thought to be a 'Splachnum' may be 'Bryum capsulis nutantibus' and the 'Lichen caeruleo-nigricans' appears doubtful, believes it may be a variety of 'Lichen calcarius'. Sending specimens of [William] Hudson's 'Helvella plana' and a similar fungus. Will give Smith the [Robert] Morison book before leaving for the Indies.
