Table IV. gives the amounts of carbon dioxide produced by ten 

 wild and ten vestigial pupae during their entire pupal life. Fig. 5 

 also shows graphically the rates of carbon dioxide production for 

 two lots of pupae. From an examination of this figure it will be 

 noted that the curves follow closely those for oxygen consumption 

 with characteristic decreases the second day, followed by steady 

 increases up to the time of hatching. Yestigials seem to have the 

 higher rate of carbon dioxide production. 



TABLE V. 



SHOWS TIME REQUIRED TO PRODUCE THE SAME AMOUNT OF CO., BY TEN- 

 DIFFERENT GROUPS OF TEN WILD AND TEN VESTIGIAL 

 DURING ENTIRE PUPAL LIFE. 



Time to Produce Same Amount of CCh Minutes.
