 be superfluous here. No matter, we are 

 amazed at the result obtained. How does 

 the Epeira come to succeed with her difficult 

 problem, so strangely managed? I am still 

 asking myself the question. 



The laying of the radii is finished. The 

 Spider takes her place in the centre, on the 

 little cushion formed of the inaugural sign- 

 post and the bits of thread left over. Sta- 

 tioned on this support, she slowly turns round 

 and round. She is engaged on a delicate piece 

 of work. With an extremely thin thread, she

 the centre, a spiral line with very close coils. 

 The central space thus worked attains, in the 

 adults' webs, the dimensions of the palm of 

 one's hand; in the younger Spiders' webs, it 

 is much smaller, but it is never absent. For

 this study, I shall call it, in future, the

The thread now becomes thicker. The 

 first could hardly be seen; the second is plainly 

 visible. The Spider shifts her position with 

 great slanting strides, turns a few times, mov-
