2l8 ALPHABETICAL COMPILATION 



Unfertilized eggs 3.7 (i3"-23 °C.),4.5 (i8°-28 "C.) ; fertilized eggs 2.2 (i3°-23°C) 

 2.5 (i8°-28°C.) (Korr, 1937). 



For (jL values see Rubenstein and Gerard (1934) and Korr (1937). For figures 

 on other eggs see Borei and Lybing (1949, p. 113)- 



B. Sperm 



1. Increase of Oj Consumption by 



/. Dilution of Sperm. — (Gray, 1928 a for Echinus esculentus and E. miliaris; Barron 

 and Goldinger; 1941 ; Barron, Gasvoda, and Flood, 1949; Hayashi, 1946; et al.). 



2. Seminal Fluid.— {HaysLshi, 1946; Nelson, 1949). 



5. lodoacetate. — And malonate, in concentrations not affecting respiration of fer- 

 tilized eggs (Barron and Goldinger, 1941). 



4. -SH Reagents. — In small concentrations; inhibit in large concentrations (Bar- 

 ron, Nelson, and Ardao, 1948; Nelson, 1949). 



5. X-rays and Hydrogen Peroxide. — Decrease in large doses, increase in small doses 

 (Barron, Flood, and Gasvoda, 1949; Barron, Gasvoda, and Flood, 1949; Barron and 

 Seki, 1952; Barron, Seki, and Johnson, 1952). 



6. Usnic Acid. — (Antibiotic) in high concentrations of sperm, decrease in low con- 

 centrations (Nelson, 1948). Little effect on respiration of fertilized eggs, but inhibits 

 cleavage (Marshak and Harting, 1948). 



7. Nitrogen Mustards. — Increase respiration of sperm, that of eggs not affected 

 (Barron, Seegmiller, Mendes, and Narahara, 1948). 



8. Ethyl Urethane. — o.i M (Barron, Nelson, and Ardao, 1948). See topic Anaes- 

 thetics. 



II. Decrease or Inhibition of O2 Consumption by 



/. Egg Water. — (Gray, ig28c found increase in Echinus esculentus, no effect in 

 E. miliaris; Hayashi, 1946). 



2. X-rays and Hydrogen Peroxide. — Decrease in large doses; increase in small doses 

 (Barron, Flood, and Gasvoda, 1949; Barron, Gasvoda, and Flood, 1949; Barron and 

 Seki, 1952; Barron, Seki, and Johnson, 1952). 



5. Usnic Acid. — (Antibiotic) in low concentrations of sperm, increase in high con- 

 centrations (Nelson, 1948). Little effect on respiration of fertilized eggs, but inhibits 

 cleavage (Marshak and Harting, 1948). 



4. HCN. — (i X io~*) inhibits (Barron, Nelson, and Ardao, 1948). 



5. Uranyl Nitrate.— XJramxxra (Benedict and Barron, 1946; Barron, Muntz, and 

 Gasvoda, 1948). 



6. Phenyl Urethane. — Saturated solution inhibits, i/ioth saturation no effect (Bar- 

 ron, Nelson, and Ardao, 1948). See Anaesthetics. 



7. -SH Reagents. — Inhibit in large concentrations, increase in small (Barron, Nel- 

 son and Ardao, 1948; Nelson, 1949). 



III. Carbon Dioxide Production (Cohn, 19 18). 



IV. Respiratory Quotient, RQ,. 1.08 (Barron and Goldinger, 1941) ; i.oi (Barron, 

 Seegmiller, Mendes, and Narahara, 1948).
