The following tools will be found very valuable: saw, square, plane, brace and bit, knife, hammer, gla.s.s cutter, files--round, flat, and triangular.

Where the circ.u.mstances will not allow of the purchase of the preceding list, the following apparatus is recommended as sufficient for the performance of a large number of the experiments:

The following may be obtained, for either list, at little or no cost from household stores or home-made sources: washing soda, sugar, salt, ammonia, coal, c.o.ke, saltpetre, sulphur, blue vitriol, alum, pota.s.s.

bichromate, blueing, lime, pickle-jars, wire gauze, candles, wire, sheet metals, test-tube holder and rack, balance, battery cells, horse-shoe magnet, pneumatic trough, lamp chimneys, tin cans, melting spoon, bicycle pump, baking-powder.

For home-made apparatus, consult _Laboratory Exercises in Physics_ by Newman, Ginn & Co., 50c., and Manual on _Manual Training_.

Reference has been made in the preceding experiments to the use of simple and easily contrived apparatus. The more of this the pupils can contrive and make under the direction of the teacher, the more valuable will be the course in Physical Science.
