of the Gulf Stream extended to the bottom in the section be- 
tween Havana and Key West, it is impossible any longer to 
account for the cold water of the sections across the Straits of 
Florida by an inflowing of cold water under the warmer water 
across the Straits of Bemini. As a further confirmation of this, 
we have the temperature of sections of the Gulf Stream taken 
off Jacksonville (Fig. 159), north and south of Cape Cañaveral
