only the leaf, though this is not the cafe throughout the whole of 

 the feed ; for if we cut it acrofs the middle, we fhall there find 

 much meal next the hulk. From N the leaf proceeds inwards, as 

 the letters N D S indicate ; lb that the two lower parts of the leaf 

 reprefented in jig. 25, at Land H, embrace or defend the whole 

 of the future Item, the external part of which Hem is Ihewn mjig. 

 2O, at the letters E and F. In this part of the flem are plainly to 

 be i^€^tn. a great number of veflels, and likewife in the leaves them- 

 felves may be feen many veliels, which here appear cut tranfverfely, 

 and fome of them longitudinally. 



The places marked by the letters T Q V and DOS, are thofe in 

 which the meal is contained, and which it was impoHible to repre- 

 fent on the paper, therefore thofe fpaces are left vacant. This 

 mealy fubftance confirts of globules larger than thofe in the meal of 

 Wheat, Rye, or Barley; and thefe again compofed of fmaller par- 

 ticles or globules, fo that thefe lall are lefs than the globules in the 

 before mentioned feeds. 



But what appeared to me worthy of note, in regard to this mealy 

 fubftance was, that the large globules I have mentioned, were not 

 of a perfect fpherical form, but every one of a peculiar fliape ; one 

 of fix, another of eight or more fides. In fhort, I can not any 

 otherwife defcribe their figure than by fuppofing a great quantity 

 of globules of wax, or any other loft flexible fubllance, thrown pro- 

 mifcuoully into a tub or box, and that, finking together by their 

 own weight or foftnefs, and thereby almoft all the air which had 

 been between them, while they were of a fpherical form, being 

 excluded, they loll their Ihape, and became compa6led or fqueezed 

 together. And thefe irregular figures they muft retain, until, being 

 diluted in a fulficient quantity of fome fluid, they may have room 

 to expand and relume their firfl: globular figure.
