Thanks for copy of Smith's "Grammar [of botany]", which "speaks the hand of a Master, concise yet full". Amused when he sees the "miserable incorrect compilations & imitations" of Smith's former work, and when Smith's "[English] Flora" is published, "the British botanist will find everything he wants in these three works of yours". If he was younger he would pursue study of the Natural Orders, and is sometimes vexed when people say the Natural System will supersede the Artificial.

He no longer has communication with Cambridge [Botanic Garden]; pleased to hear the Liverpool garden flourishes; uncertain of state of Oxford's. Pleased to see "such vast improvements" in botany and horticulture over the last 20 years, even though it renders his own work of no value. His health.

Has been reading Smith's "Selection of the correspondence of Linnaeus", which shows "how dead Botany was in England to the middle of the last century". Believes the Linnaean system was not publicly known in England until 1762, when Hope taught it at Edinburgh and himself at Cambridge, and [William] Hudson published "Flora Anglica".

Informs Smith he has repeated his offer of resigning the Walkerian Lectureship, without having anyone in view, but assuming that Smith has now finished with Cambridge.
