THE BLOOD. 55 



That which was taken away last was first coagulated, and 

 completely too, by the time I had tied up his arm, which was 

 in three minutes from the blood's first running into the cup. 



The blood which was received into the first cup coagulated 

 next, and as I observed by my watch, in twelve minutes from 

 its being set down on the table. 



That which was received into the second cup was the third 

 in order as to coagulation, and was considerably later in jellying 

 than the first; for in fifteen minutes it was not thoroughly 

 coagulated ; nay, even in twenty-two minutes a small part of 

 it was still fluid. It was remarkable that none of these three 

 had any size. 



But the blood in the third cup differed considerably from 

 that in the others ; for in five minutes it began to appear trans- 

 parent on its surface, an indication of a future size, and it was 

 later in coagulating (see Note xxi) than that in the other cups ; 

 for even at the end of twenty-six minutes a great part of the 

 coagulable lymph was still fluid, as appeared on removing the 

 pellicle that covered it ; but in thirty-five minutes it was com- 

 pletely jellied. The size in this blood was very thick and tough. 



Now this case, when carefully examined, instead of being an 

 objection to my conclusions, will, I presume, be thought a 

 strong confirmation of them. 



For, in the first place, as the blood in the third cup alone 

 had a crust, and was much later in jellying than the rest, it 

 strengthens my inference, that the disposition of the blood to 

 coagulate is lessened in those cases where the inflammatory 

 crust or size appears (see Note xxi). And as the blood ran more 

 rapidly into this cup, it showed that the heart and blood-vessels 

 had begun to act with greater force, and therefore confirmed the 

 opinion, that in proportion as these act more strongly, the dis- 

 position of the lymph to coagulate is diminished (see Note xxiv). 

 The same opinion is likewise supported by observing what 

 happened to the blood in -the first cup, which coagulated sooner 

 than that in the third, owing to the vessels then acting more 

 weakly, as was evident from the blood's trickling down the arm, 

 and from the lowness of the pulse. 1 



1 In like manner may be explained another variety in the appearance of the size 

 namely, where it is found in the first and last cups, but not in the second or third : 

 this, I suspect, seldom happens, but when it doe it may perhaps be found, on exami-
