Maury, however, recognized that in great depths on the " Washington " and by the Austrians on the " Pola " the surest guarantee of bottom having been reached was to bring in 1890-1893, the latter carrying the investigations to the Red up a sample of the deposit.
In all areometer work it is necessary to ascertain the temperature of the water sample under examination with great exactness, as the volume of the areometer as well as the specific gravity of the water varies with temperature.
The specific gravity of any sample of spirits thus determined, when multiplied by ten, gives the weight in pounds per imperial gallon, and the weight of any bulk of spirits divided by this number gives its volume at once in imperial gallons.
The following is suggested as a typical analysis sample of black tea: Albuminous matters Gummy matters.
It will thus be seen that the whole length of the stem corresponds to a difference of density of about 04, and one division to about 00074, indicating a difference of little more than a% in the strength of any sample of spirits.
