Would the Specific Gravity of all bottles of water and airbe the same ? 7. Would it be the same for all pencils madeof the sanie kind of wood and graphite ? 8. As glass is acompound of many substances, used in many different pro-portions, would you expect all kinds of glass to have exactlythe same Specific Gravity ?. Exp. 94. SUPPLEMENTARY GRAMMAB-SCBOOL WORK. 67 Exp. 95. First, find Low many shot will balance thesmall bottle; second, how many when filled with water;and third, how many when filled with kerosene oil; andfind the Specific Gravity of the oil. If you have mercuryenough, find its Specific Gravity the same way, and see ifit agrees with results obtained in Exp. 83. If you havenot enough mercury, choose some other liquid, such asstrong brine, which you can easily make by dissolving inwater as much salt as possible. Inference. Give the Specific Gravity of each. Exp; 96. (If convenient.) Find the Specific Gravityof kerosene oil with the same apparatus used with waterand mercury in Exp. 83. Inpbkence. How nearly does it agree with results foundin Exp. 95 ?
