i8o THE WONDERS OF INSTINCT 



How is this brought about? By their very powers of 

 absorption. The moisture of which the air is never de-

 into a framework and then into muslin and satin ? What 

 a number of products to come from that curious factory, 

 a Spider's belly ! I behold the results, but fail to under- 

 stand the working of the machine. I leave the problem 

 to the masters of the microtome and the scalpel.

Until then, not a movement: one would think that
