GLOSSARY. COAGULUM DENSITY. 591 



COAGULUM. See Albumen. 



CCELIAC. .Relating to the cavity of the abdomen : thus coeliac axis, 

 the short arterial trunk supplying the stomach, liver, pancreas, 

 and spleen with blood. 



COLOSTRUM. The milk first secreted after parturition ; it has an 

 evacuaut quality, and therefore serves to expel the meconiurn or 

 first excrement of the new-born animal. 



CONCEPTION. The effectual contact of the spermatozoon produced in 

 the testicle with the matured ovum expelled by the ovary. 



CONGENITAL. Applied to what already exists formed in the new-born 

 animal, in contrast with what is afterwards developed. 



CONGLOBATE. A term formerly opposed to conglomerate as applied to 

 glands. The use of conglobate now is to signify the glands of the 

 lymphatic and lacteal systems as a less vague term than lymphatic 

 ganglia. According to present views, the glands of the absorbent 

 system, or the conglobate glands, have for one office the production 

 of white corpuscles, which by a farther development become the 

 red corpuscles of the blood. 



CONGLOMERATE. Heaped together ; applied to glands consisting of 

 lobules united under the same membrane. 



CONTRACTILITY. The property in a muscular fibre in consequence of 

 which it contracts or shortens itself on the application of a stimu- 

 lus directly to itself or to the sentient nerve spread upon it, the 

 will being a stimulus which acts on it through a motor nerve. It is 

 the same property in muscles which was formerly called irritability. 



CORPUSCLES. Applied to microscopic objects in the animal fluids ; 

 for example, exudation corpuscles, the organisable nuclei contained 

 in fibrinous fluids, which are the origin of the new tissues formed 

 from such fluids. 



CREATINE, CREATININE. See Kreatine, Kreatinine. 



CROSS. See Breeding. 



CUD. See Elimination. 



CUTICLE. See Derma. 



CYTOBLASTEMA. The structureless formative substance in which the 

 nuclei and cells are imbedded in many tissues in progress of for- 

 mation ; it is the same as blastema, which last word is preferable, 

 as involving no hypothesis of cell formation. 



CYTOBLASTS. In cells the same as nuclei. 



DECUSSATION. The crossing of two filaments or two fasciculi of fila- 

 ments, like the crossing of the two lines forming the letter X. 



DEFCECATION. The evacuation of the bowels. 



DEGLUTITION. The act of swallowing. 



DEHISCENCE. Opening as the opening up of a ripe seed-vessel. 



DENSITY ; SPECIFIC GRAVITY. These expressions are used synony- 

 mously to signify the comparative weights of equal bulks of any
