To Thomas Archer Hirst

My dear Tom.

It is my lecture day1 and therefore I have not time to do more than say that I am sorry you have been smitten by that cold, though it is a malady suffered by numbers at present; and to say how pleased I am with the arrangement you have been good enough to make regarding Eddy Wynne. I sent your note to his mother2 I am sure she will be greatly satisfied by the arrangement. All that I can give you in the way of those examination papers you shall have.

Kiss Anna for me. This sentence is a proof that I am better today than I was yesterday: for then I had little thoughts of Kissing.

Your affectionate | John

There is a paper in Pogg. by Reich3 where he either confirms me or Matteucci. I have not yet seen the paper.

RI MS JT/1/T/970

lecture day: Tyndall was giving a series of weekly RI lectures on light.

your note to his mother: letter missing. Tyndall took Wynne to Queenwood on Saturday 1 March 1856 and Wynne lodged with the Hirsts in Vine Cottage. He attended Hirst’s mathematics and physics classes, as well as those of Debus and Haas. In addition, Hirst gave him six private lessons a week from 7.00 to 8.00 am. Hirst’s Journal (RI MS JT/2/32c/1188).

a paper in Pogg. by Reich: Ferdinand Reich (1789–1882), German chemist and physicist best known for his discovery of the element indium in 1868. He was Professor of Physics at the Freiberg Bergakademie. At Matteucci’s request, he repeated Tyndall’s experiments with bismuth using a torsion balance he had made to measure the density of the earth. The paper, ‘Ueber die Diamagnetische Wirkung’, appeared in Poggend. Annalen, 97 (1856), 283–96, and was translated by Tyndall as ‘On Diamagnetic Action’, Phil. Mag., 11 (1856), pp. 249–56. In fact, Reich concluded that Tyndall had been correct. See Tyndall’s Journal for 9 March 1856 (RI MS JT/2/13c/828).
