BLOOD 45 



below the larger, and others branching out of them, or 

 joining them at different angles. The larger rivers are of 

 a deep orange-red hue, the smaller faintly tinged with red- 

 dish yellow. In some of these channels the stream rolls 

 with a majestic evenness; in others it shoots along with 

 headlong impetuosity; and in some it is almost, or even 

 quite, stagnant. By looking with a steady gaze, we see 

 that in all cases the stream is made up of a multitude of 

 thin reddish disks, of exactly the same dimensions and 

 appearance as those we* saw 

 just now in the Frog's blood; 

 only that here, being in mo- 

 tion, we see very distinctly, 

 as they are rolled over each 

 other, that they are disks, 

 and not spherules; for they 

 forcibly remind us of coun- 

 ters, such as are used for 

 play, supposing they were 

 made out of pale red glass. 

 It is charming to watch

ing one of medium size, where the density is not too great 

 to see the individual disks, and fixing our eye on the point 

 where a branch issues from one side of the channel, mark 

 the disks shoot by one after another, some pursuing their 

 main course, and others turning aside into the branch, 

 perhaps so small as to allow of only a single disk to pass 

 at once. 



The streams do not pursue the same uniform direction. 

 The larger ones do indeed; and their course is from the 

 extremity of the toes toward the body i these are the
