TAKEN AT ST. ALBANS IN 1895.

In tlie autumn (September to Xovcmbcr) the mean pressure of 

 the atmosphere Tras rather high, the mean temperature was high, 

 Avith a considerable mean daily range, the air was of average 

 humidity, the sky rather bright, and the rainfall rather heavy, 

 but on less than the usual number of days. The high mean 

 temperature of the autumn is due to September being unprece- 

 dcntedly warm. October and November had identically the same 

 mean temperature, November being about as much warmer than 

 the average as October was colder. 



The difference between these seasons and the means of the 

 seasons for 1877-86 at Watford, is shown in the following table. 

 It should be pointed out that the comparison of the rainfall is with 

 an exceptionally wet series of years.
