The effects of rapid and prolonged deep breathing, I). F. Comstock {Science, 

 n. set'., 30 {1909), No. 77.9, jiii. 80//, 805). — According to the author's observa- 

 tions, dee]) and violent breathing is a mental stimulant and has a marked efl'ect 

 in diminishing muscular fatigue. For instance, it was found that after deep 

 breathing the number of times a difficult arm exercise with heavy weights could 

 be repeated without fatigue was increased 80 per cent. An increase in pulse rate 

 was noted while the rapid breathing was continued as well as the ability to hold 

 the breath for a much longer period than was otherwise the case.
