PLATE 31 



Serial temperature and salinity curves corresponding to different months 

 (see note under plate 27 relative to the number of observations). 



The curves in figures 69-72 are based on observations made approximatel3' 

 ten miles west of La Jolla in sections 40,,, 40,o, 40,,, 41,,, 41 „„ 41„, 42,,, 42,o, and 42„.
