Farther, Demokritus conceived that the diversities of taste were generated by corresponding diversities of atoms, or compounds of atoms, of particular figure, magnitude and position. Acid taste was caused by atoms rough, angular, twisted, small, and subtle, which forced their way through all the body, produced large interior vacant spaces, and thereby generated great heat: for heat was always proportional to the amount of vacuum within.[233] Sweet taste was produced by spherical atoms of considerable bulk, which slid gently along and diffused themselves equably over the body, modifying and softening the atoms of an opposite character. Astringent taste was caused by large atoms with many angles, which got into the vessels, obstructing the movement of fluids both in the veins and intestines. Salt taste was produced by large atoms, much entangled with each other, and irregular. In like manner Demokritus assigned to other tastes particular varieties of generating atoms: adding, however, that in every actual substance, atoms of different figures were intermingled, so that the effect of each on the whole was only realised in the ratio of the preponderating figure.[234] Lastly, the working of all atoms, in the way of taste, was greatly modified by the particular system upon which they were brought to act: effects totally opposite being sometimes produced by like atoms upon different individuals.[235] [Footnote 233: Theophrast. De Sensu, 65-68.] [Footnote 234: Theophrast. De Sensu, 67.

This essential intermixture, in each distinct substance, of atoms of all different shapes, is very analogous to the essential intermixture of all sorts of Homoeomeries in the theory of Anaxagoras.] [Footnote 235: Theophrast.
