 structures, for, had that been the case, the calorific quotient must 

 have been different when development ceased. Again, for partheno-

calorific quotient was 2-6. A more unexpected result was the calorific 

 quotient of eggs in sea water to which ammonia had been added. 

 Here, as Warburg showed, no cleavage goes on, but the respiratory 

 rate is slightly raised. Meyerhof found that the calorific quotient 

 of such eggs was 3-25 to 3-35, and this was the only case in which
