METEOROLOGICAL ABSTRACT. 
The meteorological abstract was prepared from the private journal of Dr. 
Kane and the notes in the log-book of the Advance. 
The latitude and longitude, ocean currents, directions, and force of winds, 
are given as in the “ log.” 
The following abbreviations, adopted by Lieutenant Maury from those of 
Captain Beecliy, are used to denote the state of the weather : 
STATE OF WEATHER. 
b for blue sky. 
p for passing showers. 
c “ clouds. 
q “ squally. 
d “ drizzling rain. 
T “ continuous rain. 
/ “ thick fog. 
cV “ snow. 
g “ dark stormy weather. 
t “ thunder. 
h “ bail. 
u “ ugly threatening weather 
1 “ lightning. 
w “ wet dew. 
m “ misty or hazy. 
A star * under any letter denotes 
0 “ cloudy. 
an extraordinary degree. 
The force of the wind is marked as follows : 
0 for calm. 
7 for moderate gale. 
1 “ light airs 
8 “ fresh gale. 
2 “ light breeze. 
9 ‘‘ stormy gale. 
3 “ gentle. 
10 “ heavy gale. ^ 
4 “ moderate. 
11 “ storm. 
5 “ fresh. 
12 “ hurricane. 
6 “ stormy. 
The state of the weather, and the direction and force of the wind, were noted 
hourly ; the daily mean and the true direction have been given in the abstract. 
Three hourly observations (with some exceptions) were made for the temper- 
ature of air, and water, and atmospheric pressure, of which the daily mean read- 
ings are given in the abstract. The readings of the aneroids are given uncor- 
rected, as mere approximations. For all of this labor 1 am indebted to the in- 
telligence and zeal of my friend, Mr. Schott, of the United States Coast Survey.
