Show The Anatomy 12. § Book 1V- TH E Seed-Café of Yellow Henbean opens on both Sides. BookIV._ the Cafe, as fometimes, but on the Pole, ia the Centre, with their the Onthe Top, is erected a Colum, about 3 an Inch long; which, as thicker end downward,theyftand readyfor a difcharge : and the Sides ofthe Ca/é being lined with a {trong and Tenfed Asembrane, they heré- bottom to the orCafe, TwoVafeular Fibres ran oppofitely from the the Cafe, top, and fo into the Colum. Along the Tracf of thefe Fibres, afunder. as it ages, gradually cleaves on both Sides , as 13. §. The Cafe is lined with a dry and thin Parchment a great Parenchymous {mooth as Glafs. In the Centre of the Café, ftands Bofs, which is, asit were, the Bed or Placentula of the Seeds 5 which other Plants. lie all over it, as in a Strawberry. And fo in many by perform the office of fo many little Bows: which, remaining faft at the Top, and (contrary to what wefee in other Plavts) opening or being Jett off at the Bottom, forceably curle upward, and {fo drive all the Seeds before them. ; ; : ; ase: Cafe fwells, gwrosle&, andat laft falls off. On the Sides ofthe Uterws nt of Throughoutthis Bed, the Veffels for the Generation and Nourifhme the from fhooting, , fmall.Fzbre — one 5 d diftribute are the seeds, direé& ones, obliquely into each Seed. CHAPS YL TE §. THE Seed. Caf of Tulip, opens with Three Sides; be- Of the US E of the Parts to the Fruit. ing, when young, a Prifm or long Triangle. From the midle of each Side, a Partition or Boord is produced 5 all three meeting in the Centre ofthe Cafe; and fo partingit into Six Stalls forthe Seed. The in- , N the forgoing Deferiptions,1 have already mention’d 2 the Ufe ofthe Parts in fomeparticulars. I fhall now a little further explain the manner oftheir fervice, like fides hereof, are, lined with a thin fmooth and glofly Parchment, that in Hen-bean; derived from the Pith; as the outfide, from the : Barque: and fo in manyother Seed-Cafes. 15. §. The Vefels, after they rife above the Stalk , are difpofed with great artifice. Forfirft, theyare divided into Three principal Branches, which run along the Three Angles of the Cafes where the Three sides, as it ages, graduallycleave afunder. From thefe chief Branches, at the Three Angles, divers leffer ones run horizontally, and Tab. 71. of EFruits: meet at the midle of each Side, From whence again, manyyet {maller ones are produced through the bredth of each Partition to their Edges in the Centreof theCa/é. Where, once more, they are diftributed into ee. veryfine and fhort Threds, whereupon hang the Seeds. 16. §. THE Seed-Cafe of Stramoninm or Thorn Apple, is divided into Four Cloféts ; Not open one into another, as in Poppy, Tulip, &e. but fo many diftin& Inclofures. In the midft of each Clofet ftands a Colum, joyned to the Side of the Clofet by a Wall or Lamine. Through the Length ofthe Colums run feveral greater and leffer Branches of Veffels, trom whence others are obliquely produced, upon which the Seeds grow. 17. §. THE Sced-Cafe of Anagallis or Pimpernel, isa little Globes whichopens not byits Meridian or Vertically, as do the former; but byits Horizon. Fordivers veryfmall F7bres, being produced from the Stalk to the midle of the Cafe 5 do there fetch a Circle, and fo divideit exactly into Two Hemifpheres : the Uppermoft of which, when the Seeds are ripe, falleth off; and fo the wind fowes them. 18. §. THE Seed-Cafe of Coded Arfwart, neither opens at the Top, nor onthe Sides, as do all the former5 but at the Bottom. It is compofed of Four Sides: the Outer Part of which, is fofter and more fucculent ; the Inner a tite and {trong Membrane. In the Centre of the Café, is erected a Pole or Colum upon which the Seeds do all hang very loofely. 19. §. Fromthis Mechanif, the manner of that violent and fur- the Cafe. For the seeds hanging very loofe, and not on the Sides the prifing Ejaculation of the Seeds, is intelligible. , Which is not a motion originally in the Seeds themfelves; but contrived by the Stradure of both to the Fruzt; and to the Seed. 2, g. And firft, the Vefels ferve for the FiguraZ, tion of the Frait.. So inan Apple, the Ten great and Pei utmolt Branches {erve not only to nourifh and feed fo, by the Arched Lines they draw, to dire& and govern the Growth thereof into an. orbicular Figure. The Dilatation of thefe Veffls, not being hindred by any Braces or Conjunction with the Interior ones. By the Slendernefs of the Aer-Vefels, asin the Root, fo here in the Fruit, much promoted. firft begun. And by their Suline Principle, 3. §. The Five midlemoft and the Five Inmoft ferve together, to figure the Goar; the former bounding the Outer, the Latter, the Iner Augles. Yor were they only Five, or were all Ten in the fame Circle, they would only make a round Cavity like that of a hollow Pith. Henceit is that Apples, in which fome fmall Threds of the Vefels {trike out into the Circumference, are very Uneven with divers Kxobs and Ridges. But Plums, Cherries, &c. where the Veféls all terminate at an Equal diftance from the Sk, are Even all round about. 4. § The Bulk of the Fruit dependeth alfo on the Braces of the Vefféls. For in Plums and Cherries, they are more numerous; but in Apples and Pears they are very loofe one from another, and fo have li- berty left them to fpread abroad. 5. §. Asalfoon their Sizes that is, onthe Size of the Aer-Veffels. Which,thelefs they are themfelves, they ferve to make a bigger Fruit. Asthe lefs they are in any Root, they ferveto make it the more ample. For the lefs they are, the more pliable to the Aitradion of the Aer : and in their Growth muft make fo many more fpiral Rings: by both which means, they make the greater Arches. And therefore a Pear is commonly a fmaller Frvit than an Apple 3 a Plum than a Pear; and a Grape, thana Plum; in all which the Aer-Vefels are ftill greater and greater. |
