 PRIM.& VLE. The first passages, or the alimentary canal from the

SANGUIFICATION. The production and continual repair of the blood 

 that is, both of the vesicular portion or blood-corpuscles, and 

 of the blood-plasma or liquor sanguinis. Into the blood-corpuscles 

 or red particles, the chyle- corpuscles and the lymph-corpuscles de- 

 rived from the glands of the absorbent system, formerly termed 

 conglobate, become gradually developed. The fibrine and albumen 

 of the blood-plasma are derived from the albuminose into which 

 the proteine compounds of the aliment are changed in the aliment- 

 ary canal and in the process of absorption by the villi of the intes- 

 tines. It is certain the red corpuscles have no power of reproduc- 

 tion ; perhaps they elaborate some material for the blood-plasma
