MESSRS. PERCY AND VAUQUELIN.
As I have alluded, in the preceding article, to the experiments of Messrs. Percy and Vauquelin, two distinguished French chemists, their testimony in this place seems almost indispensable, even though we should not regard it, in the most strict import of the term, as medical testimony. The result of their experiments, as communicated by them to the French minister of the interior, is as follows:
In bread, every one hundred pounds is found to contain eighty pounds of nutritious matter; butcher's meat, averaging the different sorts, contains only thirty-five pounds in one hundred; French beans (in the grain), ninety-two pounds in one hundred; broad beans, eighty-nine pounds; peas, ninety-three pounds; lentils (a species of half pea little known with us), fifty-four pounds in one hundred; greens and turnips only eight pounds of solid nutritious substance in one hundred; carrots, fourteen pounds; and one hundred pounds of potatoes yield only twenty-five pounds of nutriment.
I will just affix to the foregoing one more table. It is inserted in several other works which I have published; but for the benefit of those who may never yet have seen it, and to show how strikingly it corresponds with the results of the experiments of Geoffroy, Percy, and Vauquelin, I deem it proper to insert it.
Of the best wheat, one hundred pounds contain about eighty-five pounds of nutritious matter; of rice, ninety pounds; of rye, eighty; of barley, eighty-three; of beans, eighty-nine to ninety-two; peas, ninety-three; lentils, ninety-four; meat (average), thirty-five; potatoes, twenty-five; beets, fourteen; carrots, ten; cabbage, seven; greens, six; and turnips, four.
