Things required.—Some of the soHds used in the last lesson. Tea-cup, tumbler, salad-cream bottle, round medicine phial, piece of india-rubber tubing, and a large basin or pan of water. Water, milk, quicksilver, and any other liquids available. What to do. Notfice that the solid things upon the table are of different shapes, and that the shapes do not alter. Show by pouring the same amount of water or other liquid into different vessels that the shape of the water depends upon the shape of the vessel. Collect a bottle of ordinar}' gas, and use it to show that a gas has no surface and spreads itself through as much space as it can. The following is a way to do this :— Fill a bottle with water, and invert it in a basin of water; then displace the liquid with gas led from a jet by a piece. Fig. 4.—Gas is issuing from the tube and bubbling up through the water in the bottle. of india-rubber tubing (Fig. 4). Now insert a cork into the neck of the bottle while it is still under water, or cover the mouth with a glass plate, and lift the bottle out of the water and place it on the table. The gas has the size and shape of the bottle. Open the bottle and wave it about; you immediately notice.
