Warburg raanometric procedures on isolated embryos. Manometric determinations on intact embryos followed by 

 extensive calculations based on separate studies of membrane growth and respiration [ l] . Medium: A = intact egg 

 in air; B = intact egg in air and isolated tissues in Ringer-phosphate, pH 7.4; C - isolated embryo in Ringer- 

 phosphate, pH 7.2; D = isolated embryo in Krebs solution + 0.24% glucose; E = isolated embryo in Ringer- phosphate, 

 pH 7.4; F = isolated embryo in Ringer- phosphate or Ringer-bicarbonate, pH 7.4. Where values are enclosed in 

 parentheses, glucose was added to the medium. 



111 When serum instead of Ringer's solution was used in medium. Qo^ = 12.9.
