Teekham—The Sense of Sight in Spiders. 
July 16. Pushed her from the nest. She ran to the far side 
of the box where she caught and ate a gnat. At the end of an 
hour she returned to her eggs. 
July 17. Removed her from the box, surrounded her nest with 
pink paper, and put her into the box again, five inches away 
from the nest. She seemed to see it and ran toward it, but 
stopped at the edge of the paper, and lifted her head as though 
studying the situation. She then crept under the paper where 
it was loose, and so into her nest. 
July 18. Pushed her from the nest and pressed the paper 
down so that she could not creep under it again. While doing 
this we accidentally closed the opening into the nest. The 
spider soon returned, crossed the pink paper, and tried to 
get into the nest. She worked for fifteen minutes trying to 
force an entrance, going all over the nest, poking and working 
at the web with her first legs as though trying to tear it. She 
did not seem to use her falces. Some gnats were then put into the 
box, and while she was eating one we cleared the opening to the 
nest. She soon returned and went in. 
July 19. Took the spider from the box and removed the pink 
paper. Then put her back but she would not go back to her 
eggs although she was pushed close to them. We then replaced 
the pink paper. She seemed to notice it—ran onto it, and 
finally settled down under the edge where it was a little loose, 
but did not go back into her nest. 
July 20. Found her wandering about the box and could not 
make her take any further interest in the eggs. 
Astia vittata, 3. A box was prepared by papering the four 
corners, respectively, with blue, pink, red and light green 
paper. A clear space was left in the middle of each so that the 
spider could attach her nest to the sides of the box. On July 25 
the spider was put in. 
July 27. The spider built her nest and laid her eggs in the 
middle of the green paper. 
July 28, 29 and 30. Pushed her out of the nest and let her 
find her way back across the green paper. 
July 31. Took the spider out and substituted blue paper for 
green around her nest, putting green around an artificial nest
