    Si'C. ll.l Section 11. -Specific Gravity or Relative Density. 1. Heiul a glass U tulie, [ilacc nici-cury in one liiu)) and water in the otlicu'. Measure tlu^ lieigliis of the columns of mercury and of water, and calculate! tlieir respective gravities, knowing that the lieights \ary inversely as the specific gravities. 2. Place a little mercury in the U tube and care- fullv pour in watei on one side ami alcohol on the other. Note the respective heights of the two liquid columns and calculate the specific gi'avity oi the alcohol. 3. Determine the specific gravity of alcohol by Hare's apparatus (p. 21). 4. Place some water in the U tube and attach one limb of the U tube to the gas supply by an india- rubber tube. Turn on the gas and measure tlie ])res- sure in millimetres of water. 5. Take the specific gravity of a glass stopper, a piece of lead or iron, by the method of Archimedes (p. 22). 6. Weigh out 20 to 50 grams of lead shot and determine the specific gravity of lead by dropping the shot into a burette containing water, and noting the rise in the level of the water (p. 25). 7. Take the specific gravity of lead shot by weigh- ing in a specific gravity bottle filled with water (p. 25). 8. Find the specific gravity of a specimen of alcohol by the specific gravity bottle (p. 19). R
