DISEASES OF THE BI,OOD. 



Obscurity of blood changes. Toxic and globulicidal serums. Agglu- 

 tination. Corpuscular Thrombi. Red globules, biconcave, embryonic. 

 Source. Escape of immature red globules. White globules, eosinophile, 

 neutrophile, uninuclear, multinuclear, lymphocyte, granular amoeboid, strap- 

 nucleated. Conditions of increase. Relation to microbes and their pro- 

 ducts. Blood plates. Destruction of red globules in the liver. Numbers 

 in animals, in different vessels and conditions. 



The blood is the common medium through which all nourish- 

 ment is conveyed to the tissues, all material to the glands for se- 

 cretion or transformation, and all effete matter to the various 

 emunctories for elimination. It is also the carrier of oxygen 

 for the respiration of the tissues, and the seat of changes, as yet 

 little known, effected through the white globules. The activities 

 of the various processes, carried on by the fixed tissue cells and 

 nuclei would suggest, that any disease or derangement of these 

 processes would be at once cognizable in changes shown in the 

 blood. Yet so perfect is the balance of sanguification and elimi- 

 nation on the one hand, and of the remaining vital processes on the 

 other, that it has not hitherto been possible to detect in the blood 

 such changes as would identify the great majority with morbid 

 processes. Some morbid changes are however recognizable and 

 it is important that the significance of these should be known. 



The blood is a liquid, consisting of a plasma holding in solution 

 serum albumen, serum globulin, fibrine- forming elements, sugar, 

 urea, salts, and a variety of other soluble bodies, and floating a 

 series of semi-solid organized bodies, the red and white globules.
