experiments at home or in school.
It will give a practical and experimental knowledge of elementary
electricity, and thoroughly prepare students for advanced work. Full
directions are given for

TWO HUNDRED EXPERIMENTS.

The experiments and discussions are so planned that the student is
always prepared for what follows. Although the experiments may be
performed with the apparatus that is usually found in school
laboratories, the author has designed a complete set of apparatus for
those who want to have their own outfit.

Fun With Magnetism and Fun With Electricity have started more young men
upon electrical careers than any other scientific outfits ever placed
before the public. The thousands upon thousands that have been sold in
all parts of the world have furnished fun and science for people of all
ages, and the mere fact that they are listed by the New York Board of
Education, and recommend to the pupils and teachers of the New York
public and private schools is a guarantee of their value. Were it not
for the fact that these are made in such large quantities and sold by
stores, agents and mail-order houses, the price would be much higher.
Don't fail to get these. They have a national reputation.

This outfit contains a 32-page book of instructions, with 45
illustrations, together with a complete set of apparatus for performing
61 fascinating experiments. It will give you some new ideas about
magnetism and start you at the right place in your study of electricity.
Think what that means--to start right!

The book contains experiments with the horseshoe magnet, with bar
magnets, with floating magnets, etc., etc., thus giving a practical
knowledge of the subject; and it is all done in such an interesting way
that one can't help remembering it. Every experiment cli
