With exactness grinds He all.


It is, I believe, one of the most hopeful among the many hopeful
signs of the times, that the civilised nations of Europe and America

the science which does not merely try to cure disease, and shut the
stable-door after the horse is stolen, but tries to prevent disease;
and, thank God! is succeeding beyond our highest expectations. Or

wish to help themselves, and, in so doing, to help their fellow-men.
Let me quote to you a passage from an essay urging the institution of
schools of physical science for artisans, which says all I wish to
say and more:

"The discoveries of Voltaic electricity, electromagnetism, and
magnetic electricity, by Volta, OErsted, and Faraday, led to the
