_ View this Bafe attentively, and it appears to confift of lon~-’ 
gitudinal Fibres lying clofe Side by Side, and conneéted in- 
feparably without Violence, running from the Circumference 
of the Bafe to the rifing Trunk, along which they are dif- 
pofed in like manner; and the fame Texture may by good 
Glaffes be traced to the Extremities of the Branches. ‘Thefe 
Glaffes difcover, that what to the naked Eye feemed to be Fi- 
hres, are indeed {mall Tubes, of which the whole Shrub con- 
fifts, but compreffed, and fhrunk in. 
‘If we cut the Trunk, or any large Branch of thefe Kerato- 
phyta tranfverfely, and examine their Structure nicely, we 
may plainly difcover, not only the Courfe of thefe longitu- 
dinal Tubes, but, likewife, that they are circularly difpofed.

“ner as appears in the annual Circles of Wood, with this Dif- 
ference however, that in the Keratophyta the Circles do not 
adhere fo clofely to each other as in Wood; but appear 
plainly to be fuperinduced, and often with fome heteroge- 
‘neous Matter intervening.

The Part we have hitherto defcribed, is that which fome 
Naturalifts have called the woody Part of the Keratophyta ; 
‘others, from its affording when burnt a ftrong Smell like 
burning Horn, the horny. weet 
And this, in all the various Species of this kind of Bodies; 
however different in Size, Figure, and external Appearance 
they may be, appears almoft uniformiy to be the fame, ex- 
hibiting to the View a fimilar Structure, and the fame Princi- 
- ples, when chemically analyfed. _ 3 bis ny an 
Upon this horny or woody Part is fuperinduced a kind of

to their very Extremities.
