Gives details of his experiments with glutenesed plates.

Received his note and the glass last night. In case his plates have not been treated with iodide of potassium he has put some on one or two.

When he last saw him he was carrying out experiments on colors. Sends a sample of Chinese natural green dye, which has just come into his hands.

Many thanks for the 'light reading,' which he returns together with the paragraph from the Observer. Won't be able to return to the country yet as he is not fit enough. Knew the family of Reginald Poole at Bridgewater.

Still in a recumbent position and finds writing awkward. Sympathizes with JH's position in the col d'aspin, as he is afraid of precipices himself. Has had a letter from Captain Stevenson. Last quarterly was interesting on Louis Philippe.

Believes the enclosed will give him satisfaction. Four of the Horaces are now provided for. Strange way the English have of going against people's express wishes. Regarding Russia's effrontery.

An optician named Davis would like JH's opinion on an instrument he has designed for observing the sun's atmosphere. Would he look in on his way to the City? What a glorious day the 1st of May was.

Sending this message by JH's two daughters, who he hopes have enjoyed their stay.

His own health does not seem to improve. Would like to visit the German Spas he mentions but could not undertake the journey involved.

Feeling worn out with his illness. Hopes JH will be able to go to Collingwood for Christmas. Thanks for all the trouble he took over the Mint-Clark affair.

Will have great pleasure in escorting Margaret Brodie Herschel. His address will be the University Club, Suffolk St. Will make the Parliamentary experiment if JH comes.

Effect of crystals on mesmerized persons. Brompton Square was blocked by people waiting to see Marguerite Gardiner (Countess of Blessington). Gas lighting by electricity.

Regrets he could not help JH. Thought Mr. Townley had spoken to JH. His brother-in-law has seen Robert Houdini in Paris.

Engaged at the Lightning Commission. Will assist JH when he needs help. Used chart of the Antarctic region he mentioned.

Received his present this morning for which he is grateful. Comments on William Whewell's philosophy.

Is unable to be of assistance to JH in the matter of a military appointment.

About JG's intended marriage.

Has briefly come into London on distressing business.

Has examined the papers JH left with him and has no objections to the calculations; comments on these. Will forward an additional remark to Francis Baily.
