... pretty accurate; I use it on board," he said. "Well, I got the specific gravity of gold, zinc and copper from my pocket-tables, and made a few experiments with some bearing metals.

... to keep well than when cooked without sugar; not, however, because of the preservative influence of the sugar, which is too small in amount to prevent the action of germs, as in the case of preserves, but because the addition of sugar to the water or fruit juice increases its specific gravity, and thus raises the boiling point. From experiments made, I have found that the temperature of the fruit is ordinarily raised about 5 deg. by the addition of the amount of sugar needed for sweetening sub-acid fruit. By the aid of this additional degree of heat, ...
