 ANALYSIS OF THE OBSERV.\TOKY RECORDS FOR FEBRUARY, 

 1864, IN CONJUNCTION WITH THOSE OF BIRTHS, DEATHS, &c! 

 By E. SwARBRECK Hall. 



Some of the meteorological phenomena this month were adverse to health 

 and life, but those of the reverse character so much preponderated, that the 

 mortality is about 25 per cent, less than the average of February for the 

 previous seven years. 



Atmospheric pressure had the high mean of 29-943, which is + "093 above 

 the twenty years' mean for this month. The maximum pressure, 30-368, 

 occurred on the 28th; the minimum happened on the 19th, and was 29 391; 

 the month's range was consequently '977 of an inch, which is higher than the 

 four previous years. The greatest movement of the- barometer on any day 

 was a rise of + '359 00 the lst,followed by a fall on the next day of —.357. 

 There were only five other days on which the movements exceeded the fifth 

 of an inch. The perturbations of pressure were, therefore, by no means 

 great, but the high pressure was pretty uniformly continuous ; and in com- 

 bination with cold shade temperature and hot sunshine, injurious to health.
