THE AMERICAX XATURALIST [Vol. XLI 



in April. Both days were rather cool, though the sun was shin- 

 ing brightly. Still more eonclusivf, at least in regard to heat, 

 Avas the behavior of the shrew when l)rought out to be {)hoto- 

 graphed in a dish lined with white paper. The animal was exposed 

 to direct sunlight when the temperature was about 30° C. It 

 tried at every point to get under the paper lining of the dish, while 

 its breathing rapidly increased. After some 8 minutes of exposure 

 it was evidently overcome by heat, and after dancing wildly about 

 a short time on all fours, lay motionless. Long continued bathing 

 with cold water was necessary to restore it. It is evident that times 

 of daylight and even ordinary sunnner heat are not selected by 

 the shrew for its greatest activity. On the other hand, c\eii if 

 there were no direct evidence of daylight activity, the (■a])tui-c of 

 shrews by hawks (Fisher, bS03) shows that th(< animal, occasion- 

 ally come out upon the surface by day.
