vided us with two great glandular bodies, the kidneys, plac'd at the extremities of two large blood-vessels, the emulgent vein and artery, derived from the great vein and artery, very soon after their parting at the heart, the fountain of circulation. These large vessels bring and carry back the blood to and from the kidneys near the main stream, where it passes quick. And the kidneys separate these salts from it abundantly in the urine. And because this was not enough, the whole skin is fill'd with glandular pores, as further emunctories of these salts in sweat, after they are blunted and become saponaceous, by a mixture of oyl. And no doubt but the matter of insensible perspiration, which in quantity exceeds all the other evacuations put together; consists chiefly in these salts volatiliz'd. The salivary glands carry off a further part.

Thus we see how anxious nature has been to relieve her self from any ill effects thereof and to lessen the quantity, as much as may be, of those untamable bodies; which yet are very necessary to be admitted into the blood for the sake of their energy; and by their good disposition and management, all vegetable
