Regarding this marriage I will at present limit myself to quoting an entry written in Faraday's own hand in his book of diplomas, which caught my eye while in his company some years ago.

It ran thus:-- '25th January, 1847.

'Amongst these records and events, I here insert the date of one which, as a source of honour and happiness, far exceeds all the rest.

We were married on June 12, 1821.
'M.

Faraday.' Then follows the copy of the minutes, dated May 21, 1821, which gave him additional rooms, and thus enabled him to bring his wife to the Royal Institution.
