ese observations indicate a very remarkable number of 
auroras, but it should be remembered that they are denivel from 
the reports of 350 observers spread over a territory embracing 56 
degrees of longitude and si degrees of ere In order that we 
may be able to make a c mparison with former years, it is desir- 
able to have a similar r sammary o of the reports of all the Smith- 
sonian Saas and it is to be hoped that the Secretary of that 
Institution will fur us with such a summary for each year since 
he Smithsonian system of meteorological observations was com- 
menced. 
The apts summary of the auroral observations made for 
five years at Depauville, N. Y. (lat. 44° 7’ N. long. 76° 3’ W.) has 
been furnished by Mr. Henr ry Haas

The number of auroras reported for the different years is re- 
markably. uniform, and similar results have been found at other 
pega where the annual number of auroras rises as high as fifty 
upwards; but in lower latitudes where auroral displays are 
Ton equent, the indications of periodicity are unmistakable.
