not equal one such hair. If, then, 

 we suppose such a hair to be of a 

 round form, it follows that 10,000 

 threads spun by the full grown spider 

 when laken together will not be equal 

 in substance to the size of a single 

 hair. To this, if we add that 400 

 young spiders at the time when they 

 begin to spin their webs, are not larg- 

 er than one full grown one, and that 

 each of these minute spiders possess 

 the same organs as the larger ones, it 

 follows that the exceeding small 

 threads spun by these little creatures 

 must be still 400 times slenderer, and 

 consequently, that 4,000,000 of these 

 minute spiders' threads cannot equal 

 in substance the size of a single hair."
