Fig. L — Graph showing the amount of oxygen taken up and the carbon dioxide given 

 off daring the fertilisation of half a million eggs (4'06 mgrm. of egg N) of 

 E. miorotuberculatus. The lower line shows the oxygen consumption of the same 

 egg before fertilisation. Broken curve carbon dioxide output of eggs. Respiratory 

 quotient 0'92. The quantities of oxygen and C0 2 are given in cubic millimetres 

 plotted against time in minutes.
