The Water Bear, or Macrobiotics Schultzei , takes its English name 
from its resemblance to the bear. It is a microscopic form, found as a rule 
in the sand, but at times in the water. It has four pairs of legs, each 
terminated by claws; it seems to have no organs for respiration or circulation. 
The species is hermaphroditic ; the engraving illustrates their structure. 
The Wall Spider (Phalangium opilio ) has, in common with the other 
members of the family, four principal vessels as silk repositories, which are 
located, not near the mouth, as in caterpillars, but near the anus. The thread is 
composed of the threadlets pro¬ 
ceeding from five spinnerets, 
and sometimes from six. These 
spinnerets are composed of an 
infinite number of smaller 
tubes, for in this common in¬ 
sect there is recognized the 
truth that man has learned 
but slowly and painfully, that 
a combination of slight strands 
is better able to sustain a 
strain than is a cord whose 
strands are few but large. 
Thus, again, are we taught 
that the highest human wis¬

nature in the mood of a little
