In Fig. 3 we have an experiment illustrating the laws of force. A dime is placed on a table covered with a cloth or napkin. The coin can be drawn from beneath the glass without touching it or slipping anything under it. If the cloth near by be simply scratched with the nail of the forefinger, the elasticity of the material communicates the motion to the dime, which moves slowly in the direction of the finger, until it finally comes out entirely from beneath the glass.
The experiment shown in Fig. 4 is certain to result in the smashing of several eggs; we therefore advise that they should be hard-boiled in order to avoid serious catastrophes. By blowing into a claret glass containing an egg, it is possible to cause it to jump out of the glass, and with practice it may be made to pass from one glass into another.
[WHAT IS A CHRISTMAS-BOX?]
This question is not so easily answered as you may suppose; for though all little folk know that a Christmas-box is a gift made at Christmas-tide, such was not the original meaning of the word. Christmas-boxes were at first what we now call money-boxes. They were known as thrift-boxes, and consisted of small wide clay bottles with imitation stoppers, the upper part covered with a kind of green glaze. On the side was a slit into which money could be put, and as the money was collected at Christmas, the boxes in the course of time gave the name to the present.
