...Specific gravities. — By the specific gravity of a body is meant the number of times which its weight is of the weight of an equal bulk of water. Thus, when...water weigh m ounces, then one pint of milk weighs 1-03 xm ounces, and the whole four pints of the mixture weighs m + (l-03m) x 3, or m + 3-09m ounces....
