almost fill the globule, but most frequently it is 

 represented by several vesicles of brilliant appear- 

 ance, which are rendered still more apparent by the 

 addition of acetic acid. Up to the present time dis- 

 tinctive features between these globules, and those oi 

 pus, have been sought for in vain. The relative pro- 

 portion, in the blood, of white to red globules, accord- 

 ing to Moleschott,* is 1 to 357. In some cases oi 

 leucocythemia, it is increased to one-third, or even to 

 two-fifths of the globular element of the blood (Vir- 

 chow). 



The liquid portion, or plasma of the blood, coagu- 

 lates after escaping from the blood-vessels. One por- 

 tion remains liquid, and the other assumes the form 

 of a consistent and elastic mass the clot. In the 

 serum, or liquid portion, a few red and white globules 

 are to be seen floating in the colorless fluid. The 

 clot, which entangles, and consequently includes, the 

 great mass of the globular elements of the blood, is 

 composed, in addition to them, of a substance of a 

 very finely granular or fibrillated appearance, but not 

 organized (fibrine). 



Lymph giobuies. The solid elements of lymph are globules, whicl 

 resemble exactly the globules contained in the cor- 

 tical portion of the lymphatic glands, and the whitt 

 globules of the blood. These corpuscles, which ave 

 rage in diameter from 2 srth to T^th of a line, arc 

 found in considerable quantity in the vessels whicl 

 emerge from the lymphatic glands, whilst in the affe- 

 rent lymphatics, or those which enter the gland and
