0(ENOCO'LEUS,Berk. and Thwaites.— 

 A genus of Oscillatoriacea;, distinguished 

 by the filaments growing ''within a tough, 

 shinny, more or less perujanent outer coat." 

 C. Smithii forms a red mat of interlacing 

 threads on boggy soil ; the separate.filaments 

 are gTeen. C. cirrhosum, Eng. Hot. p. 2920, 

 is a De-smonema.

 earth.

C(ENU'R'US, Rudolphi. — a supposed 

 genus of Entozoa, placed in the order Ste- 

 relraintha, and family Cystica : since proved 

 to be uurse-lbrms or lar^as of lanice. 



Char. A simple vesicle filled with an 

 albuminous liquid, upon the outer surface 

 of w'hich a number of soft, short, retractile, 

 cylindrical and rugose rather than jointed 

 bodies (scolices) are situated. The head 

 of each resembles that of a T<ema, having 

 four di,slis and a crown of hooks. 



C. cerebralis (PI. 21. fig. 10) is the larva 

 of Tcenia ccenurus, which infests the dog. 



It occurs in the brain of sheep, producing 

 the " staggers ; " sometimes also in that of 

 the Hor.^e", the Ox, the Rabbit, &c. The 

 vesicle is as large as the e^g of a hen or a 

 pigeon. The scolices when extended are 

 about the 1-5 or 1-6" in length. When re- 

 tracted they appear to the naked eye as 

 opaque white specks. 



Other kinds occur in the lemur and the 

 rabbit.

COFFEE.— The "berries," as they are 

 vulgarly called, of coflee, are the seeds of 

 Cojf(Pa urnhica, a Dicotyledonous plant, of 

 the Nat. Order Cinchonacese. 



The " berries " consist of a mass of hard 

 endosperm (horny Albumen), composed of 

 closely adherent thick-walled angidar cells 

 (PI. 2. fig. 5 b), with a thick skin composed 

 of a layer of thin-walled parench^niiatous 

 cells forming a membrane, and a layer of 

 hard, easily separable, ]iitted, thick-walled 

 pareuchjinatou? cells of larger size (PI. 2. 

 fig. 5 a) ; true spiral vessels occur in the 

 groove on the inner face of the seed. Ground 

 cofl'ee is subject to very extensive adultera- 

 tions, recognizable under the microscope ; 

 by which the vascular and parenchymatous 

 tissues of roots, the starch or the integu- 

 ments of various grains and seeds, &c. (men- 

 tioned more particidarl}' under Ohicoey) 

 may be discovered.

 cordage manufactured from the fibrous tis- 

 sue of the husk of the cocoa-nut. See

COLA'CIUM, Ehr.— A genus of Flagel- 

 late Infusoria. 



Char. IHagellum single, free like ^«/7/«?ffl 

 or attaclK^d by a simple or branched stalk, 

 gTeen, with red eye-spot. 



C. vesicuhsvm '(PL 30. fig. 32). Oyato- 

 fusiform, variable, internal vesicles distinct, 

 length l-8()0". Fresh water, on Cyclops &c.

 funnel-shaped, variable, vesicles less dis-
