308 FRAGMENTS OF SCIENCE. 
her capability to return it with adequate force. But they 
met again and again, and at each successive meeting he 
found his heaven clearer, until at length he was able to say, 
" Not a moment's alloy of this evening's happiness occurred. 
Everything was delightful to the last moment of my stay 
with my companion, because she was so." The turbulence 
of doubt subsided, and a calm and elevating confidence took 
its place. "What can I call myself," he writes to her in 
a subsequent letter, " to convey most perfectly my affection 
and love for you ? Can I or can truth say more than that for 
this world I am yours? " Assuredly he made his profession 
good, and no fairer light falls upon his character than that 
which reveals his relations to his wife. Never, I believe, 
existed a manlier, purer, steadier love. Like a burning 
diamond, it continued to shed, for six- and -forty years, its 
white and smokeless glow. 
Faraday was married on June 12, 1821; and up to this 
date Davy appears throughout as his friend. Soon after- 
ward, however, disunion occurred between them, which, 
while it lasted, must have given Faraday intense pain. It 
is impossible to doubt the honesty of conviction with which 
this subject has been treated by Dr. Bence Jones, and there 
may be facts known to him, but not appearing in these 
volumes, which justify his opinion that Davy in those days 
had become jealous of Faraday. This, which is the prev- 
alent belief, is also reproduced in an excellent article in 
the March number of " Eraser's Magazine." But the best 
analysis I can make of the data fails to present Davy in 
this light to me. The facts, as I regard them, are briefly 
these. 
In 1820, Oersted of Copenhagen made the celebrated 
discovery which connects electricity with magnetism, and 
immediately afterward the acute mind of Wollaston per- 
ceived that a wire carrying a current ought to rotate round 
its own axis under the influence of a magnetic pole. In 
1821 he tried, but failed, to realize this result in the lab- 
oratory of the Eoyal Institution. Faraday was not present 
at the moment, but he came in immediately afterward and 
heard the conversation of Wollaston and Davy about the 
experiment. He had also heard a rumor of a wager that 
Dr. Wollaston would eventually succeed. 
This was in April. In the autumn of the same year 
Faraday wrote a history of electro-magnetism, and repeated
