a darker colour. Toward the top it shoots 
out many side branches, garnished with 
winged leaves, composed of sixteen pair of 
leaflets, which are broad at their base, and 
are near two inches long, of a pale colour ; 
these emit a rank odour in the summer sea- 
son, so as to be very offensive. The tfnit is 
oval, about the size of a partridge’s egg, 
smooth, of a dark colour, and opens in five 
parts, having a five-cornered column stand- 
ing in the middle, between the angles of 
which the winged seeds are closely placed, 
lapping over each other like the scales of 
fish. This tree is commonly known under 
the name of cedar in the British West India 
islands. 
CEDROTA, in botany, a genus of tlie 
Octandria Monogynia class and order. Es- 
sential character : calyx six-parted ; corolla 
none ; germ superior, surrounded by a 
gland; style short. There is but one spe- 
cies; viz. C. Guianensis; this is a lofty 
tree, forty feet in height, and two in diame- 
ter, with a thick, unequal, wrinkled bark, 
full of clefts, and is a heavy aromatic wood, 
which becomes light when dry. It grows in 
the great forest of Guiana, flowering in Mayl 
CELARENT, in logic, a mode of syllo- 
gism, wherein the major and conclusion are 
universal negative propositions, and the mi- 
nor an universal affirmative. As 
CE No man that is a hypocritg can be 
saved : 
EA Every man who with his lips only 
cries Lord, Lord, is a hypocrite : 
RENT Therefore, no man, who with his 
lips only cries Lord, Lord, can be 
saved. 
CELASTRUS, in botany, a genus of the 
Pentandria Monogynia class and order. 
Natural order of Dumosse. Rhamni, Jus- 
sieu. Essential character; corolla five-pe- 
talled, spreading; capsule triangular, trilo- 
cular ; seeds calyptrated. There are twen- 
ty-two species. This genus consists of 
shrubs or small trees, with alternate leaves, 
and the flowers many together, on axillai-y 
subdichotomous peduncles. They are 
mostly natives of America and the Cape of 
Good Hope.

CELESTINE, in mineralogy, a species 
of the Strontian genus: it is divided by 
Werner into two sub-species; viz. the fi- 
brous and the foliated : the colour of the 
former is intermediate between indigo blue 
and bluish grey, and sometimes passes into 
a milk white. It loses its colour in keep-

ing. It is found massive and in plates, also 
crystallized : the fragments are splintery. 
It shows a tendency to prismatic distinct 
concretions, which appear to be parallel 
and conformable with the fibrous fracture. 
Specific gravity is 3.83. Its geognostic si- 
tuation is very imperfectly known ; it is 
imagined to occur in marl. It is found in 
France, and at Frankstown in Pennsyl- 
vania. The foliated celestine is milk white, 
which falls into blue : it occurs massive, and 
is crystallized in six-sided tables that inter- 
sect one another. It is found in Sicily, and 
in England, near Bristol : specific gravity

CELLEPORA, in natural history, a ge- 
nus of the vermes zoophyta. Animal an 
hydra or polype; coral somewhat mem- 
branaceous, composed of round cells. There 
are eight species, of which we shall notice 
C. ramnlosa, which is found in the N orthern 
Ocean, very brittle and ranch branched, 
and appearing as if composed of grains of 
sand. C. spongites has rows of tubular top- 
shaped cells, in single layers, the openings 
of which are margined. This species inha- 
bits the Mediterranean and North seas : 
white, grey, or red, and marked on the un- 
der side of the cells with lines between each 
row ; they are from two to five inches in 
diameter. 
CELLULAR substance, in anatomy, or 
Cellular membrane, is the medium whicli 
connects and supports all the various parts 
and structures of the body. It is composed 
of an assemblage of fibres, and laminae of 
animal matter; connected to each other, 
so as to form innumerable cells, or small 
cavities, from which its name of cellular is 
derived. This substance pervades every 
part of the animal structure. By joining 
together the minute fibrils of muscle, ten- 
dons or nerve, it forms obvious and visible 
fibres; it collects tliese fibres into larger 
fasciculi ; and by joining such fasciculi to 
each other, constitutes an entire muscle or 
nerve. It thus forms an investment com- 
mon to the whole muscle, and bestows on 
each bundle of fibres, nay, on each fibre, 
down to tlie most minute threads, peculiar 
sheatlis, delicate and tender in proportion 
to the subtilty of the fibre. It joins toge- 
ther the individual muscles, and is collected
