C 1875 ) 
The Shell or Skin of thefe Seeds is compofed of fo 
exceeding a thin Membrane, that the Wind, or even 
the Seeds themlelves that are enclofed by it, would eafiiy 
break it, were it not fortified or ftifFned by thofe parts 
that I call the Ribs or Seams thereof, the which are much 
thicker than the reft of the Membrane, and thereby both 
the Seed and the Veflels themlelves are prefer ved. 
When I (liew'd a certain Gentleman, by the help of a 
Microfcope, one of thefe Seed Veffels, as alfo the Seeds 
that I had taken out of it, he was very dcfiroiis to know 
of whit fabftance thofe Seeds v/ere compofed 5 but I 
thought 'twas irapofiiWe for me to fitisfie himby Difleft- 
ing one of thofe Seeds 5 yet, having further confider'd 
of his Requeft, I found out a means of breaking one of 
thefe fmall Seeds fo cleverly, that no foreign Matter 
fhould intervene, or be mixt with it. 
In doinp: this^ I was mightily furpriz*d to find a great 
deal of Gyl coming out of one of them 5 and as each of 
thefe Seeds was of a Yellowilh Colour, fo was the Oyl 
alfo, where 'twas a; little thick 5 but where it was thin- 
jner, it was as clear as any Water ^ the other Particles, 
that lay in and about the Oyl, were 01 an exceeding 
fmallnefs. 
1 made but one little Hole or Breach in the Seed, 
whereby to fqueeze out the Oyl, and the other Par- 
ticles wherewith it was filled 5 which having done, I ob* 
fcrved that the Skin or Membrane of the Seed had no 
Colour at all in it 3 and then I could fee a great many 
more Figures in the faid Membrane, than were diftin* 
guifliable in it before : Ad as all Seeds, that are viewed 
with any exaftnefs, may be difcover'd to have two Mem- 
branes, fo it is not improbable that thefe have two like- 
wife. 
Now when we confider the exceeding fmallnefs of the 
aboveraention'd Seeds, 'tis eafie to conceive how the 
fame, after that they are full ripe,' may be fcatter'd
