1. Contributions to Meteorology.— Mean results of Meteorological 
Observations made at St. Martin, Isle Jesus, Canada East, (nine miles 
west of Montreal,) for 1854; by Cuartes Smattwoop, M.D.—The 
_ geographical co-ordinates of the place are 45° 32’ N. Lat., and 73° 36/ 
_W. Long. Height above the level of the sea, 118 feet. 
~ Barometric Pressure.—The readings of the barometer are all cor- 
rected for capillarity, and reduced to 32° F. The whole of the means 
so obtained from three daily observations taken at 6 a. M., 2 r.m., and 
Pi. 
The mean height of the barometer in January was 29-516 inches, 
in February 29-520, in March 29-024, in April 29-440, in May 29-731, 
in June 29-814. in July 29-916, in August 29-910, in September 30-001, 
in October 29-949, in November 29-764, in December 29-540 inches.
