The average latitude of the centers of low barometer was 
44°-7, and the average diameter of the Ist isobar about the low 
center was 3°12 degrees. The average latitude of the centers 
of high barometer was 45°-1, and the average diameter of the 
Ist isobar about the high center was 3°87 degrees. Since the 
average latitude of the centers of low and high pressure is so
