80 RECORD AND REDUCTION 



readings recorded give the combined pressure of the dry air and aqueous vapor; 

 the latter, however, is very small: no hygrometric observations were found 

 ■led. 

 The following tables commence with the aneroid readings, and conclude with the 

 readings of the mercurial barometer and its corresponding temperature. A few 

 occasional omissions in the record were supplied by interpolation; such figures are 

 distinguished by being placed between brackets. The mean position of the "Fox" 

 is given for each month (the daily position is already given in the preceding 

 temperature paper).
