beard. Whence it appears that the kernel is formed and nourilhed 

 from thefe very flender veflels. 



Upon examinhig this nut or kernel by the microfcope, I found that 

 its fubftance is not, like other feeds, inclofed in I'mall membranes, 

 but confifts of multitudes of minute tubes, which take their rife 

 from the hard fhell, and reach to the cavity, within the kernel, where 

 the juice I have mentioned is collefted. They are not all of an equal 

 fize, nor are they of a round figure, but rather of fix fides, whicli 

 Hiape is well adapted to permit their lying clofe together and in 

 regular order. Some of thefe are turgid with a certain fubftance, 

 which in part evaporates ; others of them contain glx)bules which I 

 judged to be chiefly filled with an oil. 



Thefe fmall tubes, which \nfig. 1 1 are to be feen at W, I cut tranf- 

 verfely, and caufed a drawing to be made of a very fmall portion, as 

 viewed by the microfcope, which mfig. 12 is exprelled by A BCD : 

 the fmall points, or dots in this figure, denote fome very I'mall parti- 

 cles, which' I obferved in thefe tubes. 



Moreover, I caufed a drawing to be made of that part of the nut 

 or kernel, where I judged the young plant to be fituated, in the 

 fliape it exhibits when feen by the eye alone, without the microfcope; 

 This occupies but a very fmall part of the kernel, and is fituated in a 

 part where its fubftance is thinnefl. A drawing of this, of the na- 

 tural fize, is to be feen atfg. 13, ABC DEF, and HEG is the part 

 which in my judgment contains the entire 3'oung plant. 



From this part I cut fome very thin dices at that end of it whicli 

 hyjig. 13 is neareft to the letter E. For I was defirous to examine 

 whether any thing would there be found bearing any fimilitude or 

 refemblance in figure to the future ftem of the tree. Some of thefe 

 flices I placed before the microfcope, and caufed a very fmall portion 

 thereof to be drawn, that it might not take up too much fpace in 

 the paper. This is reprefented in fig. 14,, at EFGHI. In this
