l1.ie firrt is, of a phuit which I had, as I believe, cut exa6lly 

 tln'ongh the middle, and it is fhewn ^^fg. 16, N O P O. Here, NOQ, 

 is the part which would become the root, and OPQ, that which 

 Avould grow upwards into a tree. And, in this young plant, arc 

 plainly to be feen the leaves with which it is naturally furnilhed. 



The other, is of a plant which I judged, had not been cut through 

 tlie middle ; for which reafon it did not appear fo large as the for- 

 mer, nor were the leaves equally confpicuous. This is exhibited at 

 ^g. 17, RSTABZ. The place of the future root in this plant is 

 niarked by R SZ, and that of the fiem by SABZ. 



yVlthough I frequently repeated thefe experiments, it was only 

 twice tiiat I could obferve the upper part or future Hem of the plant, 

 in drying, feparatc itfelf from the circumjacent parts. This repara- 

 tion I have cauied to be exprelled ill the i'ame Jig. 17, at SABZ, and 

 at T Y. 



I have generally obferved, that the young plant, in that part 

 which, in /^. -i^], is noted by EHG, occupied not more than one half 

 of the fpace there reprefented, and lay near the part marked H. 

 But, at one time, I law the young plant occupy only a third part of 

 the fpace ; whence it follows, that fuch fpace or cavity was nine times 

 as large as the plant it contained-. 



Farther, I twice obferved the young plant to lie, not precifely in 

 the middle, but rather on one fide of the before mentioned cavity, 

 whence I concluded, that it had begun to vegetate while in that part, 

 for I law that the circumjacent parts had in that place begun to fe- 

 parate from each other, fo that, had the vegetation continued, the 

 plant would have found its way out of the fliell. This feparation of 

 the parts is reprefented '\njig. 17, at AW B.
