adding 1 gm. of Na-taurocholate to 1000 c.c. of sea water (solid line) . Control in sea water,

mean. Temperature 19 ± 2° C. 



The question arises whether the rise due to these 

 organic substances differs from that produced by inor- 

 ganic salts and by acids. The writer is inclined to believe 

 that this may be the case, but prefers to await the 

 results of additional experimentation before reaching a 

 definite decision.
