Pearl coloured Moth, often found in Libraries, ,hath a body enlarged toward the Head, and groweth finaller andfmaller, till at [alt it‘d‘wmdlerh into a point in its Tail : The fabrick of this little Animal, is diyided into many fmall Apai‘timents, (difringuifhed With many crooked Lines running crofs-ways) encircled every Where with multitudes of fmall feoloped Shells, curioully faflened to each other, with thin Membranes: And every oneof thefe Shells, is again invefted, with many thin tranfparent Scales, in which the Rays of Light do fport tliemfelves; and afterward, being rcfleéied from a number of Surfaces, do reprefent the Animal to our Eyes, in a bright Shiv ver Colour. . , The front of a blew Fl'ie, is cafed with thin Flakes, and its middle spar. timent is crufted all over, both above and below, with a fine icaly Compage, and the hinder region of its body, is beautified with a blew {liming Cruft, nruch refembling Poliflied Armour. ‘ The Water Knat, confifiing of many Partitions, and its Headand Body is all cafed over with a fine Shell 5 which being tranfparent, we mayplainly difcover through it, the many operations of the Vifcera, lodged in the upper, middle, and lower apartiments. . ‘ . Within the In fome Trees the Bark hath a mofi elegant firuc'ture,.in which being $231,223? opened, are prefented many ttanfverfe ranks of Minute Cav1ties ( lodged immfigmg‘é inediately under the thin Skin, with which the Trunk is decked, as With f0 {ca‘tcdvndcr many Wings, which being {tripped off, a profpeéi offereth it felf, made up [hcsm And under thefc ringlik: Cavities are placed many oblique of many oblong fibrous Pipes, carried from the Root upward according to length, in oblique pofturesg and between them are intetfperfed many Areat, filled with red Liquor, and are of unequal fides and fliapes. ‘ The firft row of oblique Fibres being taken away, many implications of AHMMH other Filaments appear underneath, which being feared confufedly one unrhu‘c Pipes, der another, do compofe the thicknefs of: the Bark; and in this refpeéi, IE i-iiiixdiecriii'éi holdeth analogie with the Skin of Man, as it is framed of numerous plexes of fibrous Pips. 3,133,353,, Fibres, which being clofely wrought, and running irregularly one below ano;‘:r"‘f:\{lg'ni"' ther, do not keep any diflinét order. Witlicritlio‘ And the inward furface of the Bark, faflned to the wooden part of Ill? iiieThiir‘iigiic Tree confifieth of Syl'tems of hollow Fibres (big with TranfparentJuicc') "‘l‘ua‘k' between Whofe various Maeanders, are feared a great company of final] concave Arece, which are turgid with fappy Liquor, and infinuate themfclVCS into the fap of Wood. , Within the outward and inward rank of Sap Fibres, are feared in fO'n'fi Diane Chap, ll l. 0f the Cuticle of SEW/(r and {ID/mm, Plants Milky Veifels , placed in feveral Columns; between which do ll‘llng from the middle of the body of the Cortex, many tranfverfe Lines, 2",";ng f0 many Rays fireaming from the Bark, and inferred into the \Vood and Pith; thele cortical infertions may be eaiily diitinguilhed from "food, being of a darker hue, in which they reprefent the Bark, from which they are propagated. And the hard Wood is not only bedecked with fofter Cortical Fibres, devrived from the Bark tranfverflyinto the fubflance of it; but alfo the Bark on the other tide is anfwered gratefully by the Wood, out of Whofe more folid body, firong woody Filaments are emitted, and tranfplanted into the more tender bofome of the Bark.

The Baik and \Voorlt'ia mutually Hil-fi'tE tranfvetl'e FL brts into each other. In fome Trees are not only feared many final] Milky, but alfo many large Refinous, Concave Fibres, fporting themfelves in "Various Divarications,which inofculatc with each other, near the furface of the Bark of Firre Trees emit- ting Turpentine, and alfo Roline, and the Sap Veifels in thefe Trees, are placed in the inner margents of the Bark. The Cortex of Oak, is accommodated with three forts of Fibres, two being Sap Veifels ( divaricated into the outward and inward verge of the Bark, and between the Annular Fibres) are feated Refiniferous Tubes, {landing in Oval Figures: And, as I conceive, this Refinous Liquor, contributes much to the conftitution and {trength of Leather, in the tanning of it, by rendring its Compage folid and compaét, thereby enabling it to keep out Water 5 and is farther advanced in goodnefs with other unéiuous fubfiances, of Oyl, Tal- low, and Wax filling up its Pores, and defending it againft the infinuations, of Wind and Water. The Bark confifiing of variety of Sap and Milky Veffels, is fomewhat like the skin of Animals, enameled with Veffels of Milk, Blood and Nervous JUice; and the numerous Pores, befetting the bark of Roots, are fo man Colatories, fii‘eining the Liquor, emitted out of the teeming Earth, and hold fome proportion with the Minute Glands, bedecking the Skin, Whofe various bores of Veflels do filter the different Liquors, and receive the purer part into their Extremities, and difcharge the Recremental, by Excretory Dufis, ters minating into the fiirface of the Skin. Every Year the Bark is furnilhed with new rings of Veffels, which grow harder by degrees, and at lafi acquire the fubfiance of rings of fofter Wood, called commonly the Sap, which being indurated, is afterward turned into the heart of Wood, The body of a Pilinire, or Aunt, is alfo encircled with a fine Tefiaceous‘ Subfiance, as with a fuit of thin Armour, guarding the fragile texture of its molt tender V ifcera, or BOWels. A Mite is a molt minute nimble Infeé‘t, having its body encloilt‘red within a thin Oval Crufi, all befet with fmall Cavities. And Infeéts, which are not adorned with Shells, are in their Pread, coé \‘chd with divers thin Skins, the uppermoit is very thick; as in Silk-worm s, encircled with many Annular Fibres, crofling the thick skin, thefe tranfverfe, rmg-like Cartilages, fubfiituted in the places of Ribs, are f0 many HypOinoclia , to which the Mufcular Fibres are appendant, and toward them, 35 Immoveab‘lc; they conttafi themfelves,as their centers of Motion. T he outward Skin being {tript off in Silk-worms, a yellow Liquor difco-J vereth itfelf, which being held over the Fire, doth coagulate into a kind 0f Gellys the Alimentary Liquor is derived originally from the greater Arterial runks, and thence conveyed by fmaller branches into the Capillarie sa 1m" planted The Bail-t of Oak isfurniih ed \V‘Eli two forts of thit or tel;itiFJrous Tubes. The Bark be- ing fuiiiiihcd with [Tip and milky Veflcls. is like the Skin ofAri'i- mails, [met with Veins and Nerves, containing; Vitaland NervousLi-i quots. |
