CEL 



CEL 



by a gland ; style short. There is but 

 one species ; vis. C. Guianensis ; this is 

 a lofty tree, forty feet in height, and two 

 in diameter, with a thick, unequal, wrink- 

 led bark full of clefts, and is a heavy aro- 

 matic wood, which becomes light when 

 dry. It grows in the great forest of Guia- 

 na, flowering in May. 



CELARENT, in logic, a mode of syl- 

 logysm, wherein the major and conclusion 

 are universal negative propositions, and 

 the minor an universal affirmative. As

CELASTRUS, in botany, a genus of 

 the Pentandria Monogynia class and or- 

 der. Natural order of Dumosae. Rham- 

 ni, Jussieu. Essential character : corolla 

 five-petalled, spreading ; capsule triangu- 

 lar, trilocular ; seeds calyptrated. There 

 are twenty-two species. This genus con- 

 sists of shrubs or small trees, with alter- 

 nate leaves, and the flowers many toge- 

 ther, on axillary subdichotomous pedun- 

 cles. They are mostly natives of Ame- 

 rica 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 

 fibrous 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 co- 

 lour in keeping. It is found massive and 

 in plates, also crystallized : the fragments 

 are splintery. It shews a tendency to 

 prismatic distinct concretions, which ap- 

 pear to be parallel and conformable with 

 the fibrous fracture. Specific gravity is 

 3.83. Its geognostic situation is very im- 

 perfectly known ; it is imagined to occur 

 in marl. It is found in France, and at 

 Frankstown in Pennsylvania. The foliated 

 celestine is milk white, which falls into 

 blue : it occurs massive, and is crystalliz- 

 ed in six-sided tables that intersect one 

 another. It is found in Sicily, and in Eng- 

 land, near Bristol : specific gravity 3.6, 

 nearly, and the constituent parts are, ac- 

 cording to Vauquelin,

CELLEPORA, in natural history, a ge- 

 nus of the vermes zoophyta. Animal an 

 hydra or polype : corol somewhat mem- 

 branaceous, composed of round cells. 

 There are eight species, of which we 

 shall notice C. ramulosa, which is found in 

 the Northern Ocean, very brittle, and 

 much branched, and appearing as if com- 

 posed of grains of sand. C. spongites 

 has rows of tubular top-shaped cells, in 

 single layers, the openings of which are 

 margined. This species inhabits the Me- 

 diterranean and North seas : white, grey, 

 or red, and marked on the under side of 

 the cells with lines between each row ; 

 they are from two to five inches in dia* 

 meter. 



CELLULAR substance, in anatomy, or 

 CELLULAR membrane, is the medium 

 which connects and supports all the va- 

 rious parts and structures of the body. 

 It is composed of an assemblage of fi- 

 bres, and laminae of animal matter, con- 

 nected to each other, so as to form innu- 

 merable 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, tendons or 

 nerve, it forms obvious and visible fibres ; 

 it collects these fibres into larger fascicu- 

 li ; 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 fi- 

 bre, down to the most minute threads, 

 peculiar sheaths, delicate and tender in 

 proportion to the subtilty of the fibre. It 

 joins together the individual muscles, and 

 is collected in their intervals. It surrounds 

 each vessel and nerve in the body ; often 

 connecting these parts to each other by a 

 firm kind of capsule; and in a looser form 

 joining them to the neighbouring mus- 

 cles, &c. When condensed into a firm 

 and compact structure, it constitutes the 

 various membranes of the body ; which, 

 by long maceration in water, may be re- 

 solved into a cellular texture. In the 

 bones, it forms the basis and ground- 

 work of their fabric ; a receptacle, in the 

 interstices of which the earth of bone is 

 deposited. The only parts of the bodj 

 in which the cellular texture seems to be 

 wanting are, the proper substance of the 

 brain, the crystalline lens, enamel of the 

 teeth, and the insensible integuments of 

 the body ; viz. the epidermis, nails, and 

 hair. As the cellular substance is entirely 

 soluble in boiling water, it is ascribed 

 by chemists to the peculiar modification
