But in the middle of the profile (Station 10102) there is a pronounced 

 spreading of the curves between ten and fifty fathoms, which, however, 

 is limited to the mid-depths; it is probably an evidence of local dis- 

 turbances. A profile (Fig. 25) running parallel to the coast (Stations 

 10104-10102) connecting the preceding two, shows that the 42° water 

 can hardly have extended beyond the northern end of Jeffrey's Ledge,

while water colder than 40° (p. 178) was confined to the deeper parts 

 of the trough. A profile (Fig. 26) running off shore from the neigh- 

 borhood of Matinicus Island to the centre of the Gulf shows that 

 the bottom water was distinctly warmer on Jeffrey's Bank (Sta- 

 tion 10091) than in the centre of the Gulf (Station 10090). And a 

 profile from Station 10102, off Monhegan, to Station 10089, would 

 show an even greater temperature-difference between the two ends.
