ago: it comes from the conglomerate Glands that lie close to the inner side of the lower Jaw, and discharges it self near the middle of the Chin into the Mouth. The Second was found out by Steno (p) (p) Observat. Anat. de Oris Vasis.who published his Observations in 1662; this comes from those Glands that lie near the Ears, in the inside of the Cheek, and the outside of the upper-Jaw: The Third was found out (q)(q) Nuck Sialograp. by Thomas Bartholin, who gave an Account of it in 1682, and about the same Time by one Rivinus a German: It arises from the Glands under the Tongue, and going in a distinct Canal to the Mouth of Wharton's Duct, there, for the most Part, by a common Orifice, opens into the Mouth. The Fourth was discovered by (r) Ibid.Monsieur Nuck (r); he found a Gland within the Orbit of the Eye, from which, not far from the Mouth of Steno's Duct, Spittle is supplied to the Mouth by a peculiar Canal. Besides these, the same Monsieur Nuck found some smaller Glands near the last, but lower down, which by Four distinct Pipes carry some Spittle into the Mouth; so careful has Nature been to provide so many Passages for that necessary and noble Juice, that if some should fail, others might supply their Want.
