Barnard. Immediately afterwards he became a member 
of the Sandemanian Church, in which eventually he held | 
the office of elder, and frequently preached. When he was 
appointed Director of the Laboratory at the Royal Insti- 
tution, in 1825, his first act was to invite the members to 
evening meetings with experimental demonstrations, thus 
commencing the Friday evening discourses, while in the 
same year he started the juvenile lectures at Christmas. 
Eight years afterwards he was appointed Fullerian Pro- 
fessor of Chemistry. He continued to discharge these 
various duties at Albemarle Street till failing health 
rendered it impossible. During this time we see Faraday 
working often for the Government and regularly for the 
Trinity House, while the researches in his laboratory were 
never intermitted, except through illness. To enumerate 
his investigations here would be out of the question, but 
was desired by the great as well as by the wise of the 
earth. He received unsought no fewer than ninety-five 
honorary titles and marks of merit, while both the Royal 
Society and the Royal Institution in vain requested him 
to become their president. 
The book consists in a great measure of Faraday’s own 
words; to a few intimate friends, as Mr. B. Abbott, 
Huxtable, his wife, Schénbein, and De la Rive, both father 
and son, he poured out his thoughts in a rich stream. 
From these various writings it is very tempting to make 
extracts. Here are two or three :— 
“The philosopher should be a man willing to listen to 
every suggestion, but determined to judge for himself. 
He should not be biassed by appearances; have no 
favourite hypothesis ; be of no school and, in doctrine, 
hve no master. He should not be a respecter of persons,

all students of science will remember something of what he | 
accomplished in the liquefaction of gases, the preparation | 
of steel and optical glass, the ventilation of lighthouses, 
and, especially, that magnificent series of researches in 
electricity which extended from 1831 to 1855, comprising 
the induction of electric currents, the evolution of electri- | 
city from magnetism, the explanation of the voltaic pile, 
with the definiteness of electro-chemical decomposition, 
the influence of magnetism on a ray of polarised light, 
diamagnetism, the polarity of bismuth and other crystal- 
line bodies, the effect of heat on magnetic force, as well 
as the mutual relation of these various powers of nature. 
These discoveries were made known principally in the 
“Philosophical Transactions,” extending his reputation so 
much that, though living in great simplicity, his friendship 
but of things. Truth should be his primary object. If to 
these qualities be added industry, he may indeed hope 
to walk within the veil of the Temple of Nature.” 
“When a mathematician engaged in investigating 
physical actions and results, has arrived at his own 
conclusions, may they not be expressed in common 
language as fully, clearly, and definitely as in mathe- 
matical formule? If so, would it not be a great boon 
to such as we to express them so—translating them out 
of their hieroglyphics that we also might work upon them 
by experiment? I think it must be so, because I have 
always found that you could convey to me a perfectly 
clear idea of your conclusions, which, though they may 
give me no full understanding of the steps of your process, 
gave me the results, neither above nor below the truth,
