same organ, for instance, in the liver, from 

 the low to the high animal. And in this 

 sphere of the cell new relationships appear in 

 organisms seemingly far apart. The blood 

 of each animal has been foiind to be different 

 from that of any other animal, with relations 

 near and remote. Hence the blood has been 

 made the basis of ordering anew all the ani- 

 mated world. For example, the walrus, 

 through its blood, is declared to be more deep- 

 ly allied in its microscopic character to the 

 horse than to its next-door neighbor in the 

 same element of salt water, namely, the 

 whale. This suggests a new classification of 

 animals very different from the old one, which 

 looked more to the large outer form or to its 

 bony structure (for instance, to the vertebral 

 column). In such manner the inner circula- 

 tory system going around the organic cycle 

 and feeding all its activity, furnishes a fresh 

 basis of the outer system of living forms. So 

 classification is looking to the micro-organic 

 world, having been hitherto macro-organic. 

 And the consanguinity of the total Biocos- 

 mos may yet have to be settled and ordered 

 by a microscopic examination of the actual 

 blood-kinship of its entire population, vegetal 

 and animal for the plant also has its kind 

 of blood. Meanwhile the thought lies open 

 that some more pivotal system than the cir-
