Note-—The width of the bands beyond the 2d maximum, and north of Cape Hat- 
teras are somewhat indefinite 
The table shows a width in the Gulf Stream proper along the 
Atlantic coast of from 25 miles off Cape Florida to 127 miles 
off Sandy Hook. The warm water at say fifteen fathoms, 1s 
from 80 to 150 miles in width. The stream widens each way 
om Cape Florida. These several divisions of the Atlantic 
stream lose a portion of their distinctness as we pass northward 
and eastward, the stream widening. 
Fy; Limtr oF AcCURACY OF THE DETERMINATIONS. 
There are two modes by which the limits of accuracy of one 
results may be tested, by one of which their permanency Is also 
tried. In this latter mode the sections are run over in different 
years, or in the same year by different officers, so as to oon 
the observations of one year with those of the next, or of one 
2 shows that the relative 
officer with that ofanother. Table No. 2s Be acaiity

The Cubs Hokey siting was runover by Lieuts.G. M. Bache,
