Diagram 2. — Temperature curves at the surface and bottom, and at tlie intermediate deptiis of .5, 10, 20, 

 30, and 50 fathoms, arranged according to the distance, in miles, from the shore. Tlie observations were 

 made on three different days, as indicated by the letters a-a, b-b, " " '^'"' ■i'^**"'' """=• 5".i;"otoV^rooi.-= j.^ 

 the actual series of observations. 



The dotted lines indicate breaks in 



fact, this belt is occupied by a northern con- 

 tinuation of the southern or West Indian 

 Gulf Stream fauna. Our observations, both 

 on the animal life and the temperature, demon- 

 strate that the western edge of the Gulf Stream 



is much nearer this coast than it is located 

 on most modern charts. According to our 

 experience, the influence of the Gulf Stream 

 becomes decidedly marked by the rise in tem- 

 perature at a few fathoms below the surface, 



Diagram 3. — Temperature curves at the bottom and surface (o), and at 5, 10, and 20 fathoms in the 

 same localities. The curves of bottom temperatures extend from the shore to near the 800-fathom line on 



^ the Gulf Stream slope. The position of each station is indicated by the total depth placed at the head of 

 tlie vertical columns.
