248 EF. Loomis— Contributions to Meteorology. 
International Bulletin. These maps begin with Oct., 1877 and 
extend to June, 1884. Table I exhibits all the cases which I 
have found in which these maps show an isobar of 31:0 inches 
over any part of the Northern Hemisphere. Columns 3 and 4 
show the latitude and longitude of the station at which the 
barometer was highest. This station is generally near the center 
of the highest isobar but may not coincide exactly withit. Col- 
umns 5 and 6 show the pressure and temperature at the station. 
where the barometer was ‘highest. Columns 8 and 9 show (in 
degrees of a meridian) the dimensions of the bigh area measured 
in an Kast and West direction, and also ina North and South 
direction. Since a large part of the isobars represented on the 
maps are incomplete, J have extended them about each high 
center up to the isobar 30:0 inches in such a manner as seemed 
to correspond best to the incomplete curves shown on the maps. 
The numbers in columns 8 and 9 give the results obtained for 
the isobars thus completed. The lines measured in the two dif- 
ferent directions run nearly through the centers of the high 
areas. In many cases the high areas stretch out to a great dis- 
tance toward the Hast and West, particularly in a latitude 
somewhat south of the high center. In such cases the numbers 
in column 8 do not indicate the full extent of the isobar, 30:0 
inches, but only its extent near the parallel which passes 
through the center of high pressure.
