like the recent fruits, it will be a proper fubje& for thevinous fermentation. Oil is more difficultly mixed, andoily foods more fo in proportion, as that is more feparate.The Farinacea, where the oil and fugar are intimatelyblended, are the moft peifeft of Vegetable Aliment, and ofthefe the Cerealia, as you will now eafily know from theirqualities.

Animal Food differs in alkalefcency and vifcidity. TheQuadrupeds and Birds are the melt alkalefcent, the Fiftiesand Vermes the moft vifcid. Alkalefcency feems to dependon the heat of the Animal. The Quadrupeds and Birdshave the greateft heat, the Fifties and Worms leaft. A far-ther proof of the lefs alkalefcency of Fifties is, that withAnimal Food we are conftantly led by inftinft to take inVegetable Aliment. The fame inftinft has never led us totake it in with Fifties. For experiment fake, I have fome-times taken Apples along with Fifti, and found them todifturb digeftion. The flefh of Quadrupeds and Fifties ison account of its alkalefcency, more eafily diffolved, andfooner affimilated into blood, giving eafieft nouriftiment andftrength, while on the fame account it is wifely ordainedthat it is fooner expelled. Fifties and Worms, on accountof their vifcidity, are more difficultly diflolved and affimi-lated, retained longer in the fyftem, and only heating fromtheir retention, and thus even accumulating the fluids, andaffording nouriftiment to the folio parts.
