E. Loomis— Observations of the U. S. Signal Service. 18 
enumerated on page 2, for the stations nearest the center of low 
pressure. The numbers without brackets show the velocity of 
the wind in miles per hour; the numbers in brackets show the 
force of the wind estimated in units of Beaufort’s scale (1 to

in large type, to indicate the day when the barometer at that 
station was lowest.
