Dear Sir

I beg to thank you for a copy of your pamphlet ¹ on M. Foucaults experiment which has been so much discussed. At the British Assoc. ² the substance of your remarks was given to the Section A. by Sir D Brewster ³ – In some conversation I afterwards had with one or two Members, there seemed to be an opinion that the experiment you propose would succeed if friction could be suff^ly got rid of, & that this would most likely be secured by a delicate suspension by Silk fibres instead of the upright pivot. At all events it would be a very delicate exp^t to perform.

I remain Very truly yours
B Powell
