Thanks for Primula paper [Collected papers 2: 45–63]; will examine some [Edinburgh] Botanic Garden samples in its light.

Huxley visiting Edinburgh and spoke on man’s zoological relations with monkeys [see Man’s place in nature (1863)]. JHB disagrees with his views.

Thanks for paper on Linum [Collected papers 2: 93–105].

One of his gardeners [John Scott] is also studying such fertilisation and appreciates CD’s encouragement; Scott has paper to read for Edinburgh Botanical Society.

Does not know an Edinburgh nurseryman who can supply the cowslips and primroses CD wants; will try to get them from the Botanic Garden.

Hears from Hooker that CD is also examining Lythrum.
