that the Os Cribrosum is madc up of the Extremities of these Lamme?, vwhich butt upon the Root of the Nose, the Holes wherewith it is piercedbeing the Intervals between the Lamines. They are designed to upholdthe inner Tunick of the Nose ; Which Tunick, being a principal Organof Smclling, bath received from Nature a very great Expansion, be-ing folded round about together wich thele Lamines, that by this in-dustrious Mechanism (he may employ all its lengrh in a very littleRoom. This Tunick is fill’d with an innumerable Company of sinallRays, so many Branches of Arteries and Veins, and especially Nerves,by which it bath a most exquisite Sense: by its great Expansion, agreater Nurnber of the subtile Particles of Odorant Bodies strike it atthe seme Time, and so render thcir Impression more strong; and bythe Labyrinth, made by the Windings of the Lametta, they are arrestedand make a longer siay before they paß off from thence into the Breast.

For the seme Reason Nature has turnisht the seid.Tunick of the Nose withitgreatmany fmall Glands, whichopen thereinto; and so moistenir with athick and slimy Exudation, the better to intangle the Dry Odorant Particles.

This Tunick being compared in severa 1 Animals Ihews much ofthe Reason of the Delicacy of lmelling in some, above what it is in others.

For look how much a finer Nose it is that Animals have, they have like-wise so much a greater Nurnber of these Lametta , wherewith the seme Tu-nick is roll’d up in so many more folds. So the Nose of a Hound is bet-ter furnished with them than that of any other Animals. The Hare,

Fox, Cat, Wild Boar, have a Considerable nurnber of them. Those Ani-mals that chew the Cud have fewer. And Man is leß ptovided for thanany of the Rest.

i. Not only the Nurnber, but the Length also of the Lametta , is ofgreat usc for the strength ofSmelling: For which purpose most Qoadrupeds, yyy ■which either Hunt, as the Carnivorous, or distinquifh their food by the Smell,as the Graminivorouf , have their Nose nyt place d in the middle of the Face,as in Man; but prolonged to the very end.

I drew it out without Pain, or any bad Accident : But m.g,iU“uh^aster this extraction, fhe still feit some trouble in her Nose, and Moisture k-s-7--did pass with Difficulty from the Nose to the Throat. This engag-ed me, sceing no more in the Nostrils, to look 'into the Mouth, where Ipereeived behind the XJvula, a stränge Body of the Bigneß of half a Nur,which I judged to be a portion of the seme Polypus : and being encou-raged by the advice of M. Fede and M. Vary, I pull’d it out in their pre-scnee. We found it of an extraordinary Ihape; the piece by which I laiihold of it was hard, and of a dark brown ; it was fasten’d by two Branches,which seem’d to have taken their Ihape in the Nose, being each of them asbig as a sweet Almond, but their substance was softer and whiter; it had alsolittle Stallt, fomething Red, of the bigness of a Cherry Stallt.
