VI. METEOROLOGICAL TABLES FOR PROVIDENCE, R. I. Summary of Meteorological Observations made at Brown University. Lat. 41° 49' 22" N., Long. 71° 24′ 48" W. from Greenwich. Barometer reduced to the Sea-level, and to 32° Fahr., and corrected for Capillary Action. By Prof. A. Caswell.

REMARKS. The barometer used was made by J. H. Temple, Boston. It is an open cistern barometer, with a screw for bringing the surface of the mercury in the cistern to a contact with an ivory point, and a microscope for the adjustment of the upper and lower surfaces, and for the "reading off." The interior diameter of the tube is about three tenths of an inch, and the readings are to hundredths of an inch, and are uniformly taken at the top of the convexity of the mercury.

The greatest height of the barometer, corrections as above, was 30.73 inches, on the evening of the 27th and morning of the 28th of February. The least was 29.01 inches, on the 22d of December. Extreme range for the year, 1.72 inches.

On three days the thermometer in the shade stood at 970 at 1 P. M., viz. June 21st and
