other only by the various proportions and mix- 

 tures, and variously sized pores of these two 

 Bodies. 



But the reture, besides these three Covers, 

 he linds a fourth, which is the innermost, called 

 by him the Secondine , the concave of which 

 membrane is filled with a tremsparent liquor, 

 out of which the Seed is formed. Trough this 

 membrane, the Lignous Body or Seed-branches, 

 distributed in the inner Coat, at last shobt down- 

 right two flender Fibres, like two Navils, one 

 into each Lobe of the Bean : These fibres, from 

 the superficies of each Lobe, descend a little 

 way directly down; and then presently each is 

 divided into two Branches, one distributed into 

 the Lobes, the other into the Radicle and Plume. 



As for the Generation of the Seed, depen- 

 dent upon the History delivered, the saith, that 

 the Sap, hawing in the Root, Trunk and Leaves, 

 passed divers Concoctions and Separations, in 

 the manner by him described , 'tis at last, in 

 some good maturity, advenced towards the Seed : 

 The more Copious and Cruder part hereof is 

 again separated by a free reception into the 

 Fruit, or other analogous to it. The more 

 Essential part is entertained in the Seed bran- 

 ches, which being considerably long and very 

 fine , the sap becoms therein , as in the Sper- 

 matick vessels, still more mature. From hence 

 it is next deliver'd up into the Coats of the 

 Seed, as into a Womb, and the neaner part 

 hereof is again discharged to the outer Coat, 

 as aliment good enough; the finer, is transmit- 

 ted to the inner, which being a Parenchymous 

 and more spatious body, the Sap therefore is 

 not herein a meer aliment , but in onderto its 

 being farther prepared by Fermentation. The 

 Sap beiug thus prepared in the inner coat, as a 

 liquor now apt to be the matter of the future 

 Seed Embryo, by fresh supplies is theuce dis- 

 charged, or filtred, or iranspired through the 

 Secondine above mentioned ; and the depositure 

 thereof, answerable to the Colliquamentum in 

 an Egg, or to the Semen muliebre, is at last 

 made into the Concave of the same. The other 

 part of the purest sap, iinbosom'd in the ramu- 

 lets, of the Seed brauche, runs a Circle, and so 

 becoms, as the Seinen masculum , yet more 



elaborate. With this purest Sap the said ra- 

 mulets being supplied 



from 



(3043) 



from thence at last the Navel-fibres shoot (as the 

 Artery into the Colliquamentum) trough the Se- 

 condine into the aforesaid liquor, deposited 

 therein. Into which liquor being now shot, and 

 its own proper Sap or iinctures mixt therewith, 

 it strikes it thus into a Coagulum or into a 

 Body consistent and truly parenchymous. And 

 in the interim of the Coagulation, a gentle fer- 

 mentation being also made, the said Parenchyma 

 or Coagulum becoms such, not of any Constitu- 

 tion indifferently , but is raised (af as we see 

 Bread in baking) into a Congenes of fixed 

 Bubles; the parenchyma of the whole Seed 

 being such. 



The whole is illustrated by several Figu- 

 res, and these explicated with great care.
