SPECIFIC GRAVITIES OF SOLIDS AND LIQUIDS. 09<br />
Analyses No. 28 and No. 29. — Si'ecific Gkavitiks of<br />
Solids and Liquids.<br />
A—Sp. gr. of a solid by direct weight.<br />
Weight of solid <strong>in</strong> the air = w<br />
" " " water = w'<br />
w<br />
Sp. gr. — w W<br />
B.—Sp. gr. of a solid by the flask.<br />
Weight of solid = w<br />
" " flask + water = w'<br />
" " " -' " + solid = w"<br />
w<br />
Sp. gr. = (w + W) — w"<br />
O.—Sp. gr, of a body soluble <strong>in</strong> water.<br />
Weight of body <strong>in</strong> air == w<br />
" " " " oil =: W'<br />
Sp. gr. of oil = a<br />
" " " water = i<br />
<strong>The</strong> liquid displaced be<strong>in</strong>g<br />
w — w' ^ w"<br />

Sp. gr. = w'"<br />
D.—Sp. gr. of a body lighter than water and <strong>in</strong>soltible<br />
<strong>in</strong> it, e.g., Cork.<br />
Weight of cork <strong>in</strong> air = w<br />
" " lead " water = w'<br />
