where it was 35.3°/,. at 200 meters, there was probably a general 
rise, north to south, from below 35°/,. to about 35.3°/,. at 600 meters, 
at the west end of the Straits as well. This rise in salinity, from the 
Floridan to the Cuban and Bahaman side of the channel, is still 
traceable at 800 meters, where the salinity rose from 34.85—34.9°/,, 
at stations 10200 and 10203 to 35.1°/,, off Habana and 35.4°/,, off 
Gun Cay.

The future must show whether the salinities outlined above are 
normal for the Straits, there being no reliable data for comparison; 
neither, for that matter, are the subsurface salinities known for any 
part of the Gulf of Mexico, the various hydrometer readings which 
have been taken there being too high (Kriimmel, 1907, p. 357), nor
