THE SPIDER BAVISBERS. 137 



turns itself Over. No. 2, when touched, moves first, second, and fourth, 

 pairs of legs. 



August 22. Both spiders have lost power since yesterday. No. 1 

 moves only when touched. No. 2 scarcely responds at all, and has its 

 legs drawn up. 



August 24. Both alive. No. 1 is better again — indeed very lively. 

 One touch makes it move the four anterior legs up and down twelve 

 or fifteen times, without stopping. No. 2 looks like a dead spider, but 

 when it is touched there is a feeble quivering of the legs. 



August 29. No. 2 is dead. No. 1 is as lively as ever. When touched 

 it struggles for more than a minute. It can almost turn over. 



September 2. The spider gains strength, and now moves its legs 

 without being stimulated. 



September 6. The spider succeeds in turning over when placed on. 

 its back. 



September 15. The spider is still in good condition. 



No further record. 



No. 43. August 8. Took strix from a nest of quinquenotatus. It is 

 barely alive. 



August 10. When the spider is stimulated- the tip of the left an- 

 terior leg quivers a very little. 



August 12. The spider is oead. 



August 16. The body is beginning to soften and stays indented' 

 when touched. 



August 19. Spider quite dry and hard. 



No. 59. August 26. Took spider from wasp as she was dragging it 

 to her hole. It was plainly dead, the cephalothorax having been, 

 badly squeezed. 



No. 52. August 16. Opened nest of quinqnenotatus and took out 

 the spider. We cannot determine whether it is dead. Under the 

 glass there seems to be a slight quivering of the legs. 



August 17. The legs quiver. 



August 26. There is still a slight quivering in response to stimula- 

 tion. 



August 28. The spider is dead. 



A summaiy of our notes shows a very wide variation in the 

 condition of the spiders. Out of eleven that were stung three 

 were killed at once, two lived four days, one five, one eleven, 

 one twenty-three, one twenty-five, one thirty-one, and one at 

 least forty days and probably longer.
