388 CELL INTELLIGENCE THE CAUSE OF EVOLUTION 



The human being evolving from the cell to the new born 

 babe takes on all the forms of the past life of man for 

 ages. The size of the structure does not make it any less 

 complicated and difficult to produce. Take for instance 

 the spinning apparatus of the spider, the spider's weav- 

 ing machine is considered the most intricate and perfect 

 device in the world for its purpose. It has over 600 spools 

 and bobbins so small that they can only be seen with a 

 microscope, magnifying about 200 diameters. The threads 

 which the spider produces are formed in the following 

 manner : the raw material for the web is a cellulose mix- 

 ture and is contained in sacks ; muscular pressure forces 

 this liquid through minute ducts and this liquid is so 

 made that it immediately hardens into a fiber when ex- 

 posed to the air. This fiber is brought to the desired 

 degree of thickness and thinness by winding over and un- 

 der the various spools and bobbins. He has claws made 

 specifically for handling his threads and spinning machin- 

 ery and with these specially made hands he is able to han- 

 dle his machinery with wonderful skill and speed. He is 

 able with this machine to produce threads of different de- 

 grees of strength, depending on the purpose for which 

 they are to be used. The silk worm uses a similar method, 

 but his is crude compared to the spider's. The material 

 used, however, is almost the same. Man has been experi- 

 menting until he discovered the substance or raw material 

 used by the cells in the silk worm and is now able to 

 imitate it tolerably well and produce an artificial silk 

 fairly good. 



Several Germans and Frenchmen are experimenting 

 with spiders, trying to breed a special kind who might be 

 a competitor of the silk worm. Just think of what the 

 spider building cells have to do to build this spider! The 

 building of a tree, man or elephant is simple as compared
