But if the Chyine be fo far attenuated by the Motion of the Blood, that it can be entertained with it into the Pulmonary Veins, it is afterward com. municated to the left Chamber of the Heart, and thence impelled by a brisk Motion, firl't into the Common Trunk, and afterward into the Afcendent Part II.

This pituitous Humour, may either borrow its defcent from Chymous part3 mixed with the Mood, or from the Nervous Liquor iifuing from the Brain. If confidered under its firlt appreheniion, it raketh its rife from the lndiocPth and piruitous parts of the Blood, which are difpenfed into the Carvitics of the Nofirils by the External Carotides terminating into the Membranes, invefting the infide of the Nofe. This Recrcment truly bedewiug the Nofirils, if it provcth Acrimonious nerateth into a putrid Fastide Ulcer, called 01mm: But if this Recrement defiilling out of the Extreamities of the Arteries be more milde, it fometimes generateth a Carnous Excrefcence, called @olypur, often filling the Cavities of the Nolirils. The Recrements of the Nervous Liquor, may be conveyed by the Ex- Thckcmtrcamities of the Nerves, and alfo Glands, feared about the Pinge Narium, Slgunsriitiurgfr‘ by which the Brain being overcharged with Recrements, difchargeth them gauging??? by numerous Fibres, derived from the fifth pair of Nerves, implanted into ted """l'S‘mb" into the the Membrane enwrapping the ~ infide of the Nofirils : And for the defence 11""de. . . . . . , brauc of the of this Hypothefis, it may be laid, that Vertiginous, and other Cephalick Nolirils.

Another probable Argument may be brought to confirm this Hypothefis, that Perfons labouring, with Hypocondriacal Difiempers, do moft freely Spit; becaufe their Nerves being affected with overmuch Moiiiure, do ad: by the confent of a Naufearing Stomach, into which coniiderable Branches of the @ar Vagirm are inferred ', and the origen alfo of thefe Stomacic Nerves, do nearly confine on thofe belonging to the Maxillary Glands, f0 that the Maxillary Nerves are ealily drawn into confent, by the irregular motion of the neighbouring rPar Vagina: ; which being irritated by Luxuriant Moifiure, dii'tinguiihed from the three other Recrements, and is more thin then the Phlegmatick Matter, lodged in the Bronchia of the Lungs, more Glutinous, an.
