From Michael Faraday   1 August 1853

Royal Institution, | 1 August, 1853.

My dear Tyndall,

Our letters have crossed,1 and so I must teaze you again for a little moment, to say that I am sure you will do right in purchasing the apparatus2 you think of; and also I am sure you will make heat most interesting to us.3 Your letter4 seems to imply that you are a little discouraged by the infinity of objects about you: but you are taking a rest now, and there is no reason why your mind should not in its quiescent state take the hue of every subject that comes near you; even though it do yield up that of the going, for that of the coming, subject. When you brace up your mind and settle with its undivided powers upon one subject, there is no fear that it will be any way deficient, or short of its ordinary vigorous tone. My kindest remembrances to all our joint friends.

Believe me to be | Ever truly yours, | M. Faraday.

Faraday Correspondence 4: 2711

Our letters have crossed: letters 0788 and 0789. Faraday responded to letter 0783 with letter 0789. Tyndall had already sent letter 0788, which Faraday had not yet received before composing letter 0789. This is Faraday’s response to letter 0788.

the apparatus: see letter 0788. Tyndall wished to purchase multiple instruments, including a galvanometer (see letter 0711, n. 4).

make heat most interesting to us: Tyndall had earlier proposed that he teach a course of twelve lectures on the subject of ‘Heat’ (see letters 0783 and 0789, n. 2).

Your letter: letter 0788.
