Fio". 2, the distances between the rays at the circumference of the circle 

 being- rather more than the spicier could span. 



The spider now rested at the centre for a moment <;r two. It then began 

 to spin rapidly round, its head remaining towards the centre and its anal 

 extremity outwards. The spiunarets paused at each ray thread, fixed the 

 new thread there and went on to the next ray. In this way, by a gradual 

 moving out from the centre, a close spiral of four lines from the centre 

 was formed, the threads being almost equidistant from each other. This 

 done, the spider went out along one of the rays, fixed a new thread, and 

 carried it right round. The interval between the fourth and the fifth cross 

 threads was quite four or five times as great as the interval between the 

 third and the fourth. The sixth, seventh and further cross threads were 

 similarly put in. When the spaces between the rays became too wide 

 for the spider to move directly from one to another, it went up one ray, 

 attached the thread, came back along that ray till it could cross to the 

 next by an existing cross thread, went tip, the next ray, attached thread, 

 returned and so on. Finally, the last circular cross thread was fixed and 

 taken round quite close to the base threads connecting the leaves. The 

 \yeb was now as on Fig. 3.
