Fig. 3, Average oxygen consuji^tion rates during a ninety minute run 

 of the re spirometer. The lowest curve represents oxygen uptake ty the 

 sea water medium alone. The middle curve depicts the average oxygen 

 uptake by normal twenty-four hour larvae. The uppermost curve shows 

 the effect of O.OOIM glucose on the respiration of normal twenty-four 

 hour larvae.
