“2 E. Loomis—Resulis from an examination of the 
temperature at Iceland was at least one degree (Reaumur) ~ 
above the mean, and placed opposite them ina table, the tem- 
rague and numerous other stations scattered all over Europe. 
The number of months employed in this comparison was 50, 
and during this period the average temperature at Iceland was 
2°-10 R. above the mean for the corresponding months. Durin 
the same months the temperature at Vienna was 0°-94 R. below 
the mean, showing between the two places a variation from the 
mean temperature amounting to 3°-04 R. or 6°°84 Fahr. If we 
restrict the comparison to the four months from November to 
February, the difference amounts to 8°°66 
I then selected all those months in which the temperature of 
Vienna was at least one degree (Reaumur) below the mean and 
placed opposite to them the temperature at Iceland for the same 
period, and found that during the four coldest months of the 
year the result was of the same kind and quite as decided as in 
' the former comparison; but during the warmer months the 
influence was less noticeable 
Similar differences, but not quite as great, were found to pre- 
vail throughout Austria and Germany, and the same influence 
in iminished degree prevails in France, Italy and a large 
part of Russia. The period employed in this comparison seems 
to be long enough to establish a law, and I think we must con- 
clude that when the temperature of Iceland is much above the 
mean, the temperature of Central Europe is generally depressed 
low the mean, and this influence is most decided during the 
colder months of the year. 
e results thus obtained for the United States and for Hu- 
rope suggest the idea that an area of unusually high barometer 
in the central portion of North America may be the result of a 
storm Botha. at a distance of 1500 or 2000 miles in a north- 
west direction. Upon referring to a map we find that the 
Aleutian Islands are situated in this direction, and at a distance 
of about 2000 miles fro regon, and we know that in the 
neighborhood of these Islands the storms of winter are unusually 
severe and the barometer often sinks extremely low. If we 
had maps showing the isobaric curves from day to day in the 
vicinity of the Aleutian Islands, and extending to the central 
rtions of North America, it is presumed we should find that 
ow pressure near these Islands was generally attended by an 
area of high pressure in a southeast direction at a distance of 
1500 or 2000 miles. The Report of the United States Signal 
rvice for 1878 contains Meteorological observations at St. 
Paul’s Island, lat. 57°_N., long. 170° W., but I have no observ- 
ations from the interior of British America suitable for compari- 
son with them; it is, however, remarkable that in several cases
