290 Faraday on Electro-Magnetic Rotation. 



knew not pursued, my paper was printed and appeared without 

 that reference whilst I remained in the country. I have 

 regretted ever since I did not delay the publication, that I 

 might have shewn it first to Dr. VVollaston. 



Pursuing the subject, I obtained some other results which 

 seemed to me worthy of being known. Previous to their ar- 

 rangement in the form in which they appear at page 416 of 

 the same volume, I waited on Dr. Wollaston, who was so kind 

 as to honour me with his presence two or three times, and 

 witness the results. My object was then to ask him per- 

 mission to refer to his views and experiments in the paper 

 which I should immediately publish, in correction of the error 

 of judgment of not having done so before. The impression 

 that has remained on my mind ever since, (one-and-twenty 

 months,) and which I have constantly expressed to every one 

 when talking of the subject, is, that he wished me not to do so. 

 Dr. Wollaston has lately told me that he cannot recollect the 

 words he used at the time : that, as regarded himself, his feelings 

 were it should not be done, as regarded me, that it should ; but 

 that he did not tell me so. I can only say that my memory 

 at this time holds most tenaciously the following words : " I 

 would rather you should not ;" but I must, of course, have been 

 mistaken. However, that is the only cause why the above state- 

 ment was not made in December 1821 ; and that cause being re- 

 moved, I am glad to make it at this, the first opportunity. 



It has been said I took my views from Dr. Wollaston. That 

 I deny ; and refer to the following statement, as offering some 

 proof on that point. It has, also, been said, that I could 

 never, unprepared, have gained, in the course of eight or ten 

 days, the facts described in my first paper. The following 

 information may elucidate that point also ; 



It cannot but be well known, (for Sir Humphry Davy him- 

 self has done me the honour to mention it,) that I assisted him 

 in the important series of experiments he made on this subject. 

 What is more important to me in the present case, however, is 

 not known ; namely, that I am the author of the Historical 

 Sketch of Electro-Magnelisnif vih'ich appeared in the Annals of
