*The figures in this column express the difference between the two preceding columns. The greatest range of the barometer, in 24 hours, was on the 5th and 6th of February, 1.139 inches. The barometer was Lowest, February 6th, at sunrise-28.984,-attached thermometer, 59° Highest, January 17th, at 9, P. M.,=30.768, แ แ 56, The mean height of the barometric column, at the hours specified above, during the year, was 29.934; its cistern being 44 feet above the mean level of high water, Charles River, at Brighton Bridge. + 94.0 7.0 Maximum heat, July 30, Minimum 66 Feb. 10th and 17th, Range of thermometer during the year, 101.0 The external thermometer, Fahrenheit's scale, has entire exposure on the north side of the building; the sun never shines directly upon it, and it suffers from reflected heat only occasionally at the 3, P. M. observation, and this probably to a small amount; it is fixed on a bracket projecting six inches from the wall, and is six feet above the surface of the ground. The barometric observations have been corrected for capillary action, and reduced to the temperature of 32° Fahrenheit, but not for elevation. The rain gauge is a cubical box of zinc, 10 inches by the side, and rests on the surface of the ground. The hours of observation adopted in these tables, are those generally used by observers in England. The mode of notation for the winds and clouds also deserves notice. In the former case, 0 denotes a perfect calm, and 6 the greatest violence of the wind. In the latter case, 0 denotes a sky without any clouds, and 10 a sky completely overcast. As uniformity in these tables is very desirable, it is to be wished that this method should be adopted by observers throughout the country. II. METEOROLOGICAL TABLES FOR BATH, ME.
