Series I V. [July 21, i<)i i.] 



Exi'KKiMKNT 12. Two sets of free boxes iccre arranged on 

 stakes. I)> each group then- was one of each of the following arti- 

 f acts: box marked with alternate red (ind green longitudinal strides, 

 box marked with alternate black and white longitudinal stripes, 

 box mottled id III green and red, a plain red box, and a plain 

 green box. The arrangement of the boxes in each >^ronp was dif- 

 ferent, and was changed tii'ice during the experiment. The box 

 marked with alternate red and green longitudinal stripes was sup- 

 plied with honey; the others were empty. The time consumed was 

 about one and a half liours. 



Sixty-three entrances were made into the boxes marked with 

 alirrnair n-d and grec'n longitudinal stripes and one into the 

 boxed mottled with green and red; no visits were made into the 

 interiors of any of the other boxes. Bees frequently hovered 

 before other boxes and twice bees alighted on the ponieo of the 

 box marked with alternate black and white- longitudinal stripes, 

 but did not enter. The visits to the artifacts marked with 

 alternate red and green longitudinal stripes were distributed 

 forty-two to box one and twenty-one to box two. 



Exi'i.KiMKNT 13. One set of six boxes was arranged on stakes. 

 To the kinds of boxes used in experiment 12, I added a box marked 

 with alternate red and green longitudinal stripes. The box marked 

 with longitudinal red and green stripes was supplied with honey; the 

 others were empty. Starting at the left, the arrangement of the boxes 

 as follows: plain green, marked with alternate red am! green 

 longitudinal stripes, mottled with green and red, marked with alter- 

 nate black and white longitudinal stripes, plain red, marked with 

 alternate red and green transverse stripes. The time consumed 

 was about half an hour. 



Nineteen entrances were made into the box marked with 

 alternate red and green Ion-it udinal stripes; but no visits \\cre 

 made lo the interior of any other box. 



l.xri KiMt'.xi 14. The same number ami kinds of boxes were 

 used as in experiment thirteen; but the mottled red and green box 

 placed where the box containing honey had been and the box contain- 

 ing the honey icus placet! on the slake rendered vacant by the remortil 

 of the mottled box. The lime consumed was about half an hour.
