in the ligneous heart ; from which the former separates easily om 
twisting the piece; and the heart remains twisted like a cord 
composed of a multitude of layers: or longitudinal sections, in+ 
laid circularly with each other, so that a transverse section 
' presents the figure of a star, or a wheel of many radii: 
Solidity—from one line to, four in well seasoned barks; and 
in proportion as the bark is thick, compact, frangible, and 
separable from the ligneous body, in respect to the thickness of 
the cuttings will those cuttings be valuable, because in this case 
they have been gathered in the right season: but if the bark be 
thin, furry, wrinkled without, and-wot easily separable from the 
heart, the cuttings will have been from tender and unripe stalks, 
and for this reason there will not be the same fragrance and bit- 
terness as.in the others; and. the virtue will be less efficacious. 
In the interstices of the layers of the heart, there is a sub- 
stance of the nature of bark, though in small quantity, which, is: 
with difficulty disengaged on pounding the woody pari well, abut. 
it remains almost wholly reduced.to powder: ' 
_ Cutting—The bark from its solidity cuts every whol liens " 
without leaving rough edges or inequalities ; the heart, being: 
ood: and laminous, cuts always unequally. j 
- Weight—Well-grown and seasoned pieces are rather heavy in: 
proportiowaan reir thickness.; on the: ‘contrary; the ill-seasoned, 
are very light: sei 
Juice—extractive, resinous, Sones staal throughout the: 
bark, forming with it a solid’ paste with brilliant points, suf- 
ficiently distinguishable on ae the. pee with a solar or 
seflecting microscope. | 
 Smell—very fragrant, saaielial.c sophia and ‘baleen:
