Brief note alerting JH to the presence of a foreign visitor.

Invites JH to come to the magnetic conference meeting being held at the B.A.A.S. meeting.

The meetings of the B.A.A.S. council have gone well so far; JH sends more details on travel arrangements for MH [see JH's 1845-6-17].

JDH comments that he has received some corrections from [Miles Joseph] Berkeley but does not think that the number of errors justify the printing of a new page. Berkeley's manuscript was illegible, JDH had to make a new copy & look up species names in [Elias Magnus] Fries. Berkeley's corrections are generally not good, those he did for THE LONDON JOURNAL OF BOTANY contained many errors. Mentions that a paper Berkeley produced with Montague contained 70 mistakes. JDH finds it curious that [William] Wilson & [Thomas] Taylor were pleased with the work when JDH added a great deal to both of their contributions, at least Berkeley's work is his own. JDH is pleased that his father has 'weathered upon' [Lovell] Reeve, the publisher, & that the [BOTANICAL REGISTER] is coming to an end. JDH is trying to write an introduction to FLORA ANTARCTICA but he is very caught up with lectures. Discusses the series of lectures he is giving at Edinburgh [University], he does not use the useless material he is given but speaks freely rather than reading & it engages his students. He has or will cover the subjects of plant physiology, nutrition, circulation, life, irritability, respiration the Linnean system & the origin & distribution of species; he finds the last a particularly challenging subject. [Gilbert] McNab arrives in London soon. Asks that Bessy [Elizabeth Hooker] give [Joseph] Dayman their copy of FOLIA SYBILLINA. JDH has heard from Dawson [Dawson William Turner?], who is going to Yarmouth. JDH has left letters for a Mrs Sprot & Admiral Tait. JDH mentions other people that he still has to call upon in Edinburgh including the Gibsons, Craigs, Mackes, McKenzies, Kays & Fullertons. Comments that Dr [Robert] Graham is still ill.
