 iromagnetism published in the Annals. 



(To the Editor of the Annals of Pldlosopliy.) 



DEAR SIR, 



You did me the favour to insert in the second and tliird volume of 

 the Annals of Philosophy^ a paper which I had written, entitled, *' A 

 Historical Sketch of Electromagnetlsm." To that paper, the initial of 

 my Christian name only was affixed. Wishing now, for reasons which 

 will shortly be made public, to acknowledge myself as the author of it, 

 I will thank you to insert this letter in the Annals as an assent on your 

 part to the correctness of the statement which it contains. 

 I remain, dear Sir, yours, very truly, 



M. Faraday.
