HISTOLOGICAL RELATIONS OF THE BLOOD. (Lymph and Chyle.) 



I. LYMPH. 1. The liquor lymphae. 2. Its histological elements Its origin 



Uses V . . ' . ' ' " . ' - . Y . . 147 



II. CHYLE. 1. The liquor chyli. 2. Its histological elements. Its quan- 



tity Origin Uses . . . . . . 149 



III. THE BLOOD. Its physical properties Its coagulation The liquor san- 

 guinis, and the blood-corpuscle . '","' . . . . 151 



1. The liquor sanguinis. Chemical analysis Its fibrine Water 

 Albumen Fat Glucose Other organic constituents Mineral 

 constituents ; chloride of sodium and potassium, carbonate of 

 ammonia, etc. Origin of the liquor sanguinis Uses of its dif- 

 ferent elements Fibrine not the only plastic element of the blood 

 Albumen is so likewise The latter is probably the plastic ele- 

 ment of the blood What then are the uses of fibrine . . 152 



2. The blood-corpuscles. 



A. The colorless corpuscles. Their cell-membrane Their con- 



tents Their size and origin Uses Vitality of the blood 



due to them, the fibrine, and the red corpuscles . . 159 



B. The colored corpuscles. Their size Do. in the lower animals
