Faraday to John Tyndall   29 January 1853

Royal Institution | 29 Jany 1853

My dear Sir

I have only at this moment been able to read your letter¹, having laid all I could aside that I might write some simple plain notes of last F. evening²: and now that I take it up, I cannot venture to judge of your experiments or draw conclusions from them not having seen the experiments or the apparatus employed. I never can decide upon a result until I have seen the experiment it depends upon made and then never until I have considered repeated & varied the experiment[.] Pluckers conclusion is one that I do not know of my own knowledge to be correct[.] I mean the varying rate of change of the Paramagnetic & diamagnetic form of force though I have seen many experiments. I know that some of the forces of his experiments are truly stated and think he may be right but would not vouch for it or give it as my own decided opinion. There is no end to the cases in which I think it safest not to come to a conclusion least it should be erroneous[.]

Ever Truly Yours | M. Faraday
