Faraday to John Tyndall   1 August 1853

Royal Institution, | 1 August, 1853.

My dear Tyndall,

Our letters have crossed¹, and so I must teaze you again for a little moment, to say that I am sure you will do right in purchasing the apparatus you think of; and also I am sure you will make heat most interesting to us. Your letter 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.
