Shui'ic acid, and they are moreover not 

 issolved by anunoniuret of copper ; while 

 certain cell-walls of Lichens are coloured 

 blue by iodine alone, from the presence of 

 granulosa. Cell-membranes and their mo- 

 difications are examined, of course, in 

 similar preparations to those mentioned as 

 displaying the forms &c. of cells. 



further information will be given in the 

 articles relating to the structures into the 

 composition of which the cells enter.

PRniORDIAL UTKICLE. 



CELL-CONTENTS.— This term corre- 

 sponds, in regard to vegetables, to the word 

 endochrome as used by Thwaites, Ralfs, and 

 some of the French botanists. It refers 

 here most essentially to the pi'otoplasm or 

 primordial utricle, as this is the part effec- 

 tive in development ; while the substances 

 imbedded in or lying in the cavity of this 

 are variable according to age, stage of deve- 

 lopment, &c. See Peimordial utricle. 



CELLA'RIA = Salicornaria. 



CELLE'PORA, Fabr.— A genus of In- 

 fnndibulate Polyzoa, of the suborder Chei- 

 lostomata, and family Celleporidye. 



Distingmshed by the massive, globose, 

 and incrusting, or erect and branched, 

 calcareous polypidom, and the irregularly 

 heaped vasiform cells, vertical to the com- 

 mon plane, with a beak on one or both sides, 

 furnished with an avicularium. Seven 

 British species. 



C. pumicosn. Rough, porous, massive ; 

 cells suborbicular, the mouth round. Com- 

 mon. 



C. vitrina. Incrusting; cells ovoid, very 

 small, pearly, and irregularly arranged.

CELLULA'RIA, Pallas.— A genus of 

 lufundibulats Polyzoa (Bryozoa), of the 

 suborder Cheilostomata, and family Cellu- 

 lariidfe. 



Distinguished by the jointed, branched, 

 erect polypidom, with flat, linear branches ; 

 the contiguous cells in two or three rows, 

 perforated behind, and more than four 

 between two joints; and the absence of 

 avicularia and vibracula. One British 

 species : 



C. Peachii (Cellularia Peachii, var., John- 

 ston). Cells narrowed downwards, truncate 

 and somewhat rounded above ; usually a 

 small spine at the upper and outer angle ; 

 three to five perforations behind ; orifice 

 oval, regular ; margin somewhat thickened, 

 minutely granular ; ovicell globular with a 

 tessellated surface. On stones &:c. from 

 deep water.

CELLULA'RIID.E.— A family of In- 

 fundibulate Polyzoa (Bryozoa), of the sub- 

 order Cheilostomata. 



Distinguished by the branched, erect 

 polypidom, and the flat, linear branches, 

 with the cells in one plane. Genera : 



Cellularia. Cells in two or three rows, 

 contiguous, perforated behind, more than 

 four between two joints ; no avicularia nor 

 vibracula. 



Menipea. Cells oblong, narrowed down- 

 wards, not perforate ; one or two avicularia 

 below the orifice in front. 



Scrupocellaria. Cells with a vibraculum
