place in the state of his mind. Among his friends was Mr. Edward Barnard, 

 one of a family living in Paternoster Row, with which he had long been 

 intimate, and which agreed with his own family in its religious views. 

 Faraday proposed to, and ultimately was accepted by, Mr. Barnard's 

 sister, Sarah. 



Mt. 29 (1821). 



March 11, Sir H. Davy wrote : — " Dear Mr. Faraday, I have spoken to 

 Lord Spencer, and I am in hopes that your wishes may be gratified ; but 

 do not mention the subject till I see you." This wish was probably to 

 bring his wife to the Institution. In June he was appointed superinten- 

 dent of the house and laboratory, in the absence of Mr. Brande. 



All obstacles were removed, and the marriage took place on the 1 2th of 

 Jane. Mr. Faraday, desiring that the day should be considered just like 

 any other day, offended some of his near relations by not asking them to his 

 wedding. 



In a letter to his wife's sister, previous to the marriage, he says, " There 

 will be no bustle, no noise, no hurry occasioned even in one day's proceeding. 

 In externals, that day will pass like all others, for it is in the heart that 

 we expect and look for pleasure." 



A month later, at a meeting of the congregation, he was fully admitted 

 as a member of the Sandemanian Church. 



His common-place book shows that he read little. In a letter, May 19, 

 to M. G. De la Rive, he says, " Mr. Stodart and myself are continuing our 

 experiments on steel, which are very laborious." 



On July 12, a paper was read to the Royal Society on a new Compound 

 of Chlorine and Carbon, by Phillips and Faraday. This, as well as Faraday's 

 previous paper on two Chlorides of Carbon, was printed in the Philoso- 

 phical Transactions. In the Quarterly Journal he had a short paper on 

 the Vapour of Mercury at common temperatures. 



On the 12th of September he writes the following letter to M. G. De la 

 Rive : — 



" You partly reproach us here with not sufficiently esteeming Ampere's 

 experiments on electro-magnetism. Allow me to extenuate your opinion a 

 little on this point. With regard to the experiments, I hope and trust that 

 due weight is allowed to them ; but these you know are few, and theory makes 

 up the great part of what M. Ampere has published, and theory in a great 

 many points unsupported by experiments, when they ought to have been ad- 

 duced. At the same time, M. Ampere's experiments are excellent, and his 

 theory ingenious ; and for myself, I had thought very little about it before 

 your letter came, simply because, being naturally sceptical on philosophi- 

 cal theories, I thought there was a great want of experimental evidence. 

 Since then, however, I have engaged on the subject, and have a paper in 

 our Institution journal, which will appear in a week or two, and that will, 

 as it contains experiment, be immediately applied by M. Ampere in sup-
