Of the 81 cases enumerated in this table, the number for each 
month in the year was as follows: 
January, 29; February, 4; March, 5; October, 1; Novem- 
ber, 8, and December, 34° We thus see that 79 per cent of 
the whole number of cases occurred in the months of December 
and January; and none occurred during the six warmer 
months of the year. 
Of these $1 cases, 74 occurred over Huropasia ; 6 over North 
America and one over the Atlantic Ocean near the South- 
western extremity of Ireland. Table II shows the latitude 
and longitude of the 74 stations over Huropasia at which a 
pressure above 31:0 inches was recorded; and also the number 
of cases occurring at each of these stations.

With but one exception, these stations are all situated be- 
tween the parallels of 50° and 60°. ‘'T'askend, being situated so 
far south of the other stations, has a suspicious appearance. 
According to the International Bulletin its altitude above sea 
level is 1607 feet, but the altitude is marked by ? as if con- 
sidered doubtful. It seems probable that the assumed eleva- 
tion is a little too great, and that the barometric pressure, 
reduced to sea level, is consequently somewhat too great. 
With but one exception, all of the 81 cases included in Table 
I are situated over the continents, and almost invariably at a 
considerable distance from both the Atlantic and Pacifie 
Oceans, and the exception named occurred near the coast of 
Ireland. Not a single case of pressure amounting to 31:0 
inches has been found over the Pacific Ocean, although one 
ease occurred in the northwestern part of North America near 
Behring Strait. These facts clearly show the influence of the 
continents in favoring the formation of areas of very high 
pressure; and over Europasia these cases occur chiefly between 
the parallels of 50° and 60°. 
The observations in able I indicate that these high areas 
are nearly stationary in position. At each station from day to 
day there are slight fluctuations of pressure which give to the 
high center the appearance of moving rapidly to and fro, but
