Forwards William Burnett's paper on medicine and medical statistics for the Manual. It exceeds the desired length but JH may prune it as he thinks fit.

Has just received the enclosed communication from Sir Hilgrove Turner, lately Governor of Bermuda. Believes JH is the only person who can deal with it.

Owing to ill health has had to quit H.M. service at the Cape and has been residing with his brother. Intends applying for the position of curator of the herbarium at Trinity College, Dublin, and would welcome a testimonial from JH. Sending this letter c/o W. J. Hooker as he does not know JH's address.

Delayed thanking him for the testimonials until he could give news of the outcome of his application. Position is still undecided, but he cannot be made professor as he does not possess an M.D.

Has been appointed Curator of the Herbarium at Trinity College, and his friend Dr. G. J. Allman professor. Is very pleased, and the use of library and society makes up for the loss in salary compared with the Cape. JH's testimonial had great weight with the authorities.

Chair of Botany at Edinburgh is now vacant and Joseph Hooker intends applying for it. Would be grateful if JH would supply a testimonial for Hooker. There is only one other candidate for the position.

When he was staying with Headlam he arranged to show him round a chemical works. Wonders if the sketch JH made at the time of a method for reducing chemical fumes is still extant. Would be glad to receive a copy of it, and the name of the works.

Remembers taking him round the chemical works of Losh, Wilson and Bell, but is unable to give any news of the manuscript as Mr. Losh is away on the continent. Hopes he will visit them again in the future.

Has submitted a paper on the projection of a star on the moon's disc to the R.A.S. Wishes to draw JH's attention to it. Comments on some of his observations.

Sent him a paper on differential equations about a month ago and wonders if it has gone astray as he has heard nothing from JH.

Regrets any inconvenience he has caused but is grateful for JH's act and offer to communicate his paper to the R.S.L.

Wishes he had seen JH's paper before submitting his own; then he could have rectified his errors. Has been carrying out some electrical experiments. Sent abstract to Michael Faraday, who does not understand them. Would be pleased to send JH further scientific communications.

Has been investigating the Cavendish experiments recently repeated by Francis Baily. Thinks G. B. Airy has neglected the resistance of the air in his mathematical theory. Would like to send an abstract of his investigations so that JH can judge their merits.

Is grateful for his letter on the Cavendish experiment. Gives outline of his own theories regarding certain aspects of the Cavendish experiments, and would like his opinion on these before they are incorporated into a paper.

Sends his manuscripts. Discusses some of Michael Faraday's experiments, in particular his theory on the non-magnetism of blood. Has sent Faraday a paper on the action of voltaic currents.

Thanks for prompt reply. Does know something about blood and circulation, but may not have expressed himself clearly. Thinks Michael Faraday has made important discoveries in magnetism and electricity.

Is little conversant in physiology so is unable to discuss GH's theories. Suggests some alterations to the text of the article.

Agrees wholeheartedly with JH's recommendation for his paper. Will rewrite it if necessary. Hopes JH will produce a second edition of his work on finite differences.

Is having an astronomical clock constructed and would like his advice on the calculation of some of the movements. Gives a brief description of the clock.

Last letter to JH was private [see GA's 1845-4-1].
