track of storms and high areas. Mount Washington, that we 

 have just studied, lies almost directly in the path of storms that 

 cross the TJnited States, and a little to the north of the ordinary 

 path of hiiih areas. Sonnblick is also on a long range of moun- 

 tains, and not an isolated peak. The nearest base station on the 

 north side is Salzburg (53 miles), and on the south side Gorz (100 

 miles). The difference in height between Sonnblick and Salzburg 

 is 8,723 feet, which is not quite one-half greater than Mount 

 Washington above Burlington. On projecting the temperature 

 curves at these Austrian stations we are struck at once with the

enormous difference in the character of the curves. I have shown, 

 as compared with those in this country, the curves for the month 

 of March, 1888 (Fig. 2). We see at once that there is a marked 

 similarity in the bendings of the curves; but the fluctuations are 

 very moderate, and do not have sharp points, as was to be ex- 

 pected from what has already been said. One of the more 

 marked discrepancies in Fig. 2 occurs on the 26th, which shows a 

 deep depression at Salzburg, and none at Sonnblick. On project- 

 ing the temperature curve at Gorz (shown broken in Fig. 2), we 

 see that the curve for Sonnblick coincides exactly with that at 



Gorz. This is a very significant fact, and shows that the moun- 

 tain range is a serious drawback to a study of this question from 

 these observations. Taking out all the coincidences, we may say

there are about 75 per cent fairly satisfactory, though hardly 

 more than 50 per cent, perhaps, as marked as at Mount Washing- 

 ton. I think these discrepancies are due to the causes already set

 with the coincidences at Mount Washington. There are two 

 quite interesting discordances in the whole set of curves, and
