It may be observed, however, that I have never seen the mercury lower than to the northward of the 71st degree of latitude; so that the above range in the months of -^Vpril to July, must be very uncommon. The greatest range of the barometer observed in the month of April du- ring seven years, was from to , or inches ; the greatest range in May during 12 years, was from to , or inches; the greatest range in June during 10 years, was from to , or inches; and the greatest range observed in July during six years, was from to , or 1 inch. The average range in April is about inches; in May , in June , and in July The changes in the pressure of the atmosphere, in the spring of the year, as indicated by the baro- meter, are not only great and rapid, but frequently portentous. I never knew the barometer mark a pressure of less than 29 inches, without its being followed or accompanied by a gale of wind, either at the place of observation, or in the immediate neighbourhood of it; and in the course of my ob- servations of the oscillations of the mercury during sixteen successive voyages, not above five or six storms have, I think, occurred, which were not pre-.
