= N{0-5 + *26596 841 + *3426 S/+ 0*1782 S/)}, 
where S^. is the skewness recorded in Table IV. 
Since the skewness is in our case small, it is sufficiently close for barometry to 
take the chance of a reading of the barometer being less than the mode, as : 
0*5 + 0*266 S/., 
and greater than the mode, as 
0*5 — 0*266 S^. 
The corresponding probabilities for the barometric height less and greater tlian tne 
mean will be found to be : 
0*5 — 0*133 and 0*5 + 0*133 respectively. 
The following is the table of stations arranged according to their respective 
chances of the barometer exceeding its modal and mean heights :
