Burge, W. E. Comparison of the Catalase Content of the Breast Muscle 

 of Wild Pigeons and of Bantam Chickens. (Science, November 2, 1917.) — 

 Energy for muscular work is generally conceded to be derived from oxida- 

 tion of food materials. Catalase is an enzyme which liberates oxygen from 

 hydrogen peroxide. The investigation here described showed that the 

 breast muscles of the pigeons which were accustomed to extensive flight 

 liberated far more oxygen than did those of the Bantams which were 

 unaccustomed to flight, while in Pigeons kept in confinement the amount 

 of catalase decreased. This would indicate that catalase " may play a role 

 in the oxidative processes of the body." As is frequently the case with 

 those not interested in systematic zoology Mr. Burge gives one no idea 

 what his " wild pigeons " may have been. They were certainly not the 

 bird popularly known by that name.
