Show “The Anatony ——-BookIV. Book IV. of Fruits, 6. §. From the fame Caufe, it is alfomoft agreeable, That the Fruit thould not come before the Leaves or Flower, but laft of all. For the Aer-Veffels, as hath been often noted, are not exactly Cylindrick, CiRCA B. VLE but tapered; that is, not only the F7bres confifting ofdivers ofthefe Vefféls, but the Vefels themfelves, as they afcend into the Track, Branches, Leaves, Flower, and Fruit, grow {till more and moreflender. So that the {malleft coming laft, and being the moft pliable; they are alfo beft accommodatedfor the Expanfion of the Parenchyma into that we call the Fruit. 7. §. Itis likewife a proper Queftion to be asked, Howit comes to pafs, That fome Plats beara Fruit, and not all? I anfwer, That Ofthe U S E of the Parts to the Seed. Andthe TIM E, in which the Uterus or Fruit andSeed-Cafe are formed. oy ND firft, for example, in an Apple, the Five Inx moft Branches, do beft ferve for the Generation of a the Seed; thefe running into the Aftire of the as the Size of the Aer-Vefils conduceth to the Bulk of the Fruit, and the Order of itsGrowth: So the Number of them, totheir being, or not being, any Fruit at all. Forthe Fruit, as we have already defined it, isan Oferds, which grows moyfter and fofter, as the Sced ripens. The reafon therefore, why the Uferws in fome Plants, conti- nues moift andfoft after the Seed is ripe; and in fome, dries ups is, Becaufe in the former, there is a fmaller, in the latter, a greater Quan- ty of the Aer-Vefels in proportion to the other Parts of the Uterus, and foa greater quantity ofAer, Whichas in the Pith of moft Plants, fo here, by degrees excludes the Sp, or rendring it more evaporable, comes in the room of it 3 and fo the Userus is dryed up: that is, there is no Frat produced, but only a Seed-Cafe. Becaufe the former is furnifhed with many Lignous Veffels, the Sulphureous or Oyly Tindfure whereof, being copioufly mixed with the Acid of the Paren- chyma, produce that Taj? Whereas the Pulp, whichis very fower, is void ofall manner ofVeféls. But if the sap-Vefels are either lef numerousorlefs Sulphureous, theygive fo mild a Tindure to the Parexchyma, as notto produceabitter, but a {weet or foft Taf; asin Apples,Grapes, Goosberries, &c. And of aGoosberry, it is particularly to be noted, that whereas, in a Limon, the Pulp only is fower, as being void of Veffels: here, on the contrary, the Pulp only is fweet, whereinto all the Veffels ftrike, and the Rindfower. 9. § Thediverfities of the Skit lf have their U/é. And therefore, the more tender and delicate the Frvit is; the Ski, on the con- trary, is thicker and more tough. So Apples have a thicker Sin, than Pears 3 Plums, than Apples; and Grapes than Plums; thofe having as it were, only a Coat of Kid, butthis of goodthick Buff from the Seed by which means, it becomes a more compact and denfer Body, than the Fruit, and fo more accommodate to the procefs of Vegetation 5 as P. 2. Che: 6. 5. hath formerly been thewed. 2. §. The Elongation likewife of the Seed-Vefféls, in the Fruit and Cafe, fometimes directly, as in Plums and Nuts, and fometimes by fe- veral Ambages before they fhoot into the Seeds, as in Tulip 5 thewes a defign for the higheft refining and maturation of the Seminal Sap. ? 8. §. From the Size, Number, and Pofition of all the Veffels in Fruits a reafon alfo maybe given, for thediverfity of their Tafis. Some In{tances have before been given; to which I hall add one or two more. So the Rind ofan Orange, is bitters the Pulp, fower. Ox Flower, and carrying off the moft Aerial spirit Andthere- fore fome Fruits, although tender, yet either not havingfo rich a Fyce, or coming early, and fo not being expofed to exceflive heats, have a very thin Ski, as Mulberries, Strawberries, &c. 3. §. Chiefly by means of the Inmoft Yeféls, is made that Chanel in fome Pears, and efpecially in Quinces. For thefe perifhing with the Flower, the circumjacent Parenchyma fhrinks up, leaving the faid Chanelin the midft. Defigned for an inlet to the Aer, for the better drying of the seeds ; whichhere {tand the more in need ofit, becaufe encompafled with a Mucilage. 4. §. For the better drying of the Seed, and the disburfing or fowing ofit in due time, the opening of the Ca/éis, in the fame manner, alfo contrived: either at the Top, as in Popy; ox on the Sides, ag in Tubp, Pimpernel; or at the Bottom, asin Codded Arfmart. All which Openingsare effected by the running of the Aer-Veféls along thofe pla. ces: for by drying the Parenchyma next adjacent,they caufe it to chop andcleave afunder. 5. §. Ofthe Seed-Cafe of Poppy, it is particularly to be noted, That as the feveral Windows, ferve to let in 4er, for the drying of the Seeds, after their full Growth: keep out Ruiz, So the Canopy over them, ferves to Forhere, the Cznot cleaving downthe Side, as it ufually doth 5 fhonld the Raiz get in, it would ftandin it, as ina Pot, and fo rot the Seeds. And as the Cawopy~ferves to preferve the Seeds 5 {o the feveral Partitions or Walls, fortheir better Stowage. For by an eafie furvey of this little piece of Ground, itis plain, that as they {tand on both Sides every Wall, there is as much more Ground for them to ftand upon, as if there were no parting Walls, but the Seeds {tuck all round about upon the Ambit or Sides of the Café 5 or upon great Bed or Placenta withinit, asin Hyofeyamus, Anagallis, &c. where there is alef§ numerous Brood. 6. g. 3 hi } ai A Mi |
