Show The Anatomy Book I which, in that they differin nothing fave in pilessin I pe ly here juft take notice of them. And thefe three Pats, fe Pe ] << Body, the Radicle, and the Elem, are concurrent to the making up o eed 5 a re than thete 2 cE We ae taken a view of the Orgartical Parts of the Beay, and other Seeds; let us next examine the Sinilary, fe. thofe whereof the Organical are composd: a diftinct obfervation of which, for aclear underftanding ofthe Vegetation of the Seed, and of the whole Plant arifing thenceis requifite: To obtain which, we muft proceed “ay ' Bue : 7 re A.tiebing a Bean then, the firft Part occurring is its Cuticle, The Eye and firft Thoughts, fuggeft it to be only a ne chi and glofly Superficies; but better enquiry difcoversit areal atic ee Tis fo exquifitely thin, and for the moft part, fo firmly continuous with the Body of the Beam, that it cannot, exceptin fome {mall Rag, be di- ftinétly feen , which, by carrying your Knife aflant into the Beav, and then very gently bearing upward what you havecut, will feparate,and thewit felf tranfparent. This Cuticle isnot only{pread uponthe Cozvex of the Lobes, but alfo on their Flats, where they are contiguous, extending it felf ikewife upon both the Radicle and Pluawe,and fo over the whole Bean. : ii 1 17. §. This Part, thoughit be fo far common with the Coats of the Beaz, as to be like thofe, an Ivteguasent 5 yet are we ina quite different Notion to conceive of it: For whereas the Coats, upon fetting the Beaz, do only adminifter the Sap, and, as being fuperfeded from their Office, then die as {hall be feen: this, on the contrary, with the Organical Paris ofthe Bean,is nourilhed, augmented, and bya real Vegetation co-extended. 18. §, Nexttothe Cuticle, we come tothe Parenchyma it felf; the Part throughout which the Izmer Body, whereof we thall {peak anon, is diffeminated ; for which reafonI call it the Parenchyma. Not that We are fo meanlyto conceiveof it, as if (according totheftricter fenfe of that word, ) it were a meer conereted Juyce. For it is a Body verycurioufly organizd, confifting of an infinite number of extreme {mall Bladders 5 as in Tab. 1. is apparent. The Surface hereof is fomewhat denfe, but inwardly,’tis ofa laxer Contexture. Tf you view it ina Microfcope, or witha very good Spefacle-Glafs, it hath fome fi- militude to the Pith, whilefappy in the Roots and Trunks of Plants 5 and that for good reafon, asin Ch.2. thall be feen. Thisis beft fen in green Beans. . 19. §. This Part would feem byits colour tobe peculiar to the Lobes of the Beans but as is the Cuticle, fois this alfo, common both to the Redick and Plume; that is, the Parenchyma or Pulp of the Bean, as to its effential fubftance, is the fame in all three. The reafon whythe colour of the Plime, and efpecially of the Radicle, which are white, is fo different from that of the Lobes, which are grcen, maychieflydepend upontheir being more compact and denfe, and thence their dif ferent Tin@ures. And therefore the Lobes themfelves, which are green while the Bean is young 5 yet when it is old and dry, become. whitifh too. Andin many other Seeds, as Acorns, Almonds, the Kernels of Ap- ples, Plums, Nuts, Gc. the Lobes, even frefh and young, are pure white as the Radicleit felf, 20. § Book L 20. §. ofPlants. But although the Parenchyma be commo n, as is faid, to all the Organical Parts; yet in very differing proportions. In the Plume, where it is proportionably leaft, it maket h about three Fifths of the whole Plume 5 inthe Radicle, it maketh abovefive Sevenths of the whole Radjcle 5 andineach Lobe, is fo far Over-proportionate, as to makeat lea{t nine Tenths of the whole Lobe. 21. §. By what hath been faid, that the Parenchyma or Pulpis not the only conftituting Part, befides the Cuticle , is imply’d: there being another Body, ofan effentially different fubftance, embof om'd herein: which may be found not only inthe Radicl e and Plume, but alfo inthe Lobes themfelves, and fo in the whole Bean. 22. §. This Inner Body appears very plain and confp icuous in cutting the Radicle athwart, and fo proceeding by degrees towards Tab.t.f. 10; the Plime, through both which it runneth in a large In the Lobes, being it is there in fo very {mall propor and ftrait Trumk, 11, & 12. ly feen, efpecially towards their Verges, Yet if tion, °tis difficult. with a fharp Knife you fmooth ly cut the Lobes of the Bean athwart, divers {mall Specks, ofa different colour from that of the Parenc hyma, ftanding therein all soba fad along ina Line, may beobferv’ds which Specks arethe Terminations ofthe Branches of this Inner Body, 23. §. For this Ivner body, asit is exifte nt in every Organical Part ofthe Bean; fo.is it, with refpect to each Part, moft regula rly diftributed. Ina good part of the Radicle ‘tis one entire Trunks towards the Bafis thereof, ‘tis divided into three main Branches ; the mid- Tah. fol, dlemoft runneth dire@ly into the Plumes the other two on either fide it, after a little fpace, pafs into the Lobes; where the aid Branch es dividing themfelves into other fmaller ; and thofe into more,and {maller again, are terminated towards the Verges of each Lobes in which manner the faid Izwer Body being diftributed it becomes in each Lobe a true andperfect Root. 24. §. Ofthis Seminal Root, as now we'll call it, from the Defcription heregiven, it is further obfervable; That es hereof; in which the {everal Ramifications the two main Branchted, are not committed intothe Seminal Trunkin each Lobe are all uniftand at right angles with That andthe Radicle of the Plime, nor yet {pect towards them both : but being produc , and fo with equal rerenchyma of the Radicle, are at aft united ed through part ofthe Pzand make acute Angles therewith: as maytherein to the main Trunk, be 25. §- This seminal Root being fo tender, feen in the fame. f.14. Tobit. fi 14. cannot be perfeGlyexcarnated, (as may the Veféls in the Parts accurate Hand. Yet by difleGtion begun of an Animal) by the moft and continn’d, as is above declared,its whole frame and diftribution may beeafily obferv'd. Again, if youtake the Lobe ofa Bean, and lengthwife pare off its Parenc hyma by degrees, and in extreme thin flices, many Brazches of the Seminal Root, (which by theother way of Diffe@ion were only noted by fo many Specks) bothas they are fewer about the Bafis of the Beay, and more nurierous towards its Verges,in fome good nefs will appear. Forthis you muft have new diftinétion and entireBeans - orelfe foaked in Water, or buryed for fome time, 26. §. AstheJzner Body is branched out the Plume: For if you cut the Plime athwar in the Lobes, fois it in t, and from the Bafs proceed along the Body thereof, youl therein find, firft, one large Trunk or |
