Faraday to George Venables Vernon   22 August 18521

Royal Institution | 22 Aug 1852

Sir

As regards Electrical observations I suppose Peltiers instrument as used by Quetelet2 would suit your purpose best. They are made by Mr Becker3 whose card I enclose and he could inform you of their price & where you could find instructions how to use it.

I do not know of any portable magnetometer that would be of any use in determining the magnetical elements. At the same time I should say I have not given my attention to the practice of observation or the use of the instrument & am not aware of all the varieties[.]

I am Sir | Your Very Obedient Servant | M. Faraday

G.V. Vernon Esq
