CEA 
solution of lunar-caustic is the proportioft of 
from 8 to 12 crains in an ounce of water, 
and has been found an excellent remedy in 
cases of ring-worm, as it is called, that is, 
when the hair falls off in patches from the 
head. 
Caustic curve, in the higher geometry, a 
curve formed, by the concourse or coinci- 
dence of the rays of light, reflected or 
refracted from some other curve. See Ca- 
TACAUSTIC. 
CAYENNE peppei-. This is the levigated 
or ground pod of the plant commonly known 
to us by the name of capsicum. There are 
many varieties ; but the principal are ; 
1. The berberry capsicum, much resembling 
that fruit in size and colour, though infinitely 
more glowing. It is perhaps the most pun- 
gent of all the vegetable simples with which 
w'e are acquainted. 2. The long-pod, wdiir.h 
is extremely common, and generally gl ows 
as large as a man’s middle finger. 3. The 
c.ockspur, which takes that name from its 
shape, and is highly pungent. 4. Tlie 
caffree, which is round and wrinkled, and 
ordinarily about the size of a small medlar. 
All these may be raised from the seed on 
hot-beds, and be planted out in June. They 
are biennials in their native climate; viz. 
in Cayenne, whence the pepper derives its 
name, and in every part of the torrid zone ; 
but we cannot keep them through the win- 
ter. Cayenne is esteemed a stimulant, and 
commonly has a place among the sauces, 
&c. intended for the table. 
CAYS, a term used by sailors to denote 
the little islands and rocks that are almost 
every where dispersed among the IE est 
India islands. 
CAZEMATE, or Casemate, in fortifi- 
cation, a certain retired platform in the 
flank of a bastion, for the defence of the 
moat and face of the opposite bastion. 
CEANOTHUS, in botany, a genus of the 
Pentandria Monogynia class and order. 
Natural order of Dumosae. Rhamni, Jus- 
sieu. Essential character; petals five, sac- 
cular, vaulted; berry dry, three-celled, 
three-seeded. There are six species, of 
which C. Americanus, American ceanothus, 
or New Jersey tea, seldom rises more than 
Three or four feet high in England, sending 
out branches on every side from the ground 
iipw'ard. These branches are ornamented 
with oval pointed leaves, having three longi- 
tudinal veins running from the foot-stalk to 
the point, and diverging in the broad part of 
the leaves from each other ; at the extre- 
mity of each shoot the flowers are produced 
CED 
in close thick spikes, and are composed of 
five small petals of a clear white. These 
appear in July, making a pretty appearance 
during their continuance ; for as every shoot 
is terminated by one of these spikes, the 
whole shrub is covered over with flowers, 
the branches growing very close to each 
other, and when the autumn proves mild 
these shrubs often flower again in Octo- 
ber. 
CECROPIA, in botany, a genus of the 
Dioecia Diandria class and order. Natu- 
ral order of Scabridae. Urticre, Jussieu. 
Essential character, male ; spathe cadu- 
cous ; ament imbricate, with turbinate 
scales, compressed-quadrangular ; corolla 
none ; female as in the male ; germs imbri- . 
cate ; style one ; stigma lacerated ; berry 
one-seeded. There is but one species, viz. 
C. peltata, trumpet-tree, or snake-wood ; 
this tree commonly rises to a considerable 
height, being seldom under forty feet in the 
most perfect state. The trunk and branches 
are hollow every where, and stopped from 
space to space with membranous septas, 
answering to so many light annular marks in 
the surface. The wood of this tree, when 
dry, is very apt to take fire by attr ition : 
the native Indians always kindle their fires 
in the woods by rubbing a piece of it against 
some harder wood. The bark is strong and 
fibrous, and is frequently used for cordage. 
It is a native of South Ai-'erica, Jamaica, 
and other West India islands. 
CEDAR, comprehended by Linneens 
among the junipers. See Junipek. Cedar- 
wood, which is of a fr agrant smell and fine 
grain, is almost incorruptible by reason of 
its bitterness, which renders it distasteful to 
worms. Historians tell us, that some of 
this timber was found in the temple of 
Apollo at Utica, 2000 years old. The cedars 
of Lebanon are famous, as having been 
used by Solomon in building. the temple at 
Jerusalem. 
CEDRELA, in botany, a genus of the 
Pentandria Monogynia class and order. Na- 
tural order of Miscellaneae. Meliae, Jussieu. 
Essential character; calyx withering; co- 
rolla live-petalled, funnel form, fastened by 
the base to the receptacle to one-third of 
its length ; capsule woody, five-celled, five- 
valved ; seeds imbricate downwards, with a 
membranaceous wing. There is but one 
species ; viz. C. odorata, Barbadoes bastard 
cedar; rises with a straight stem to the 
height of 70 or 80 feet ; while young the 
bark is smooth, and of an ash colour ; but as 
it advances, the bark becomes rough, and of
