Faraday to George Merryweather   28 March 1851

Royal Institution, March 28, 1851.

I beg to thank you most heartily for the copy of your work on the “Tempest Prognosticator,”¹ which I have read with great interest.

I perceive you have read an account of an Evening that I gave on the Researches of Quetelet with Peltier’s instrument². I have no doubt you have quoted the “London Medical Gazette”³ accurately; nevertheless I thought you would rather know of certain errors it contains before a new edition of your work comes forth. In the first place, it was not Pelletier ⁴, but Peltier, who invented the Electro-meter. It is curious that both men lived at the same time in Paris, and both were scientific.

At page 50, line 3, the name should be Quetelet, not Peltier.

At page 51, bottom line, the name should be Peltier, not Quetelet. Quetelet carefully refrained from putting forth any theory.

At page 52, line 9, for “they,” it should be “the former.”

M. Faraday
