TEMPERATURE.

There is again an increase in the number of obsei*vations fur- 

 nished to the Club this year, and a few hygrometrical returns 

 are also appended. But it is hoped that the next Report will be 

 more full and ample in this department. 



Wylam. — On glancing at the subjoined table, showing the dif- 

 ference of the monthly temperature for the year from that of the 

 average of the monthly temperature for twelve years, one cannot 

 but be struck with the violent fluctuations of the mean monthly 

 temperature of the four first months of this year from the normal 

 temperature. January was 4-7° below, February 4-4° above, 

 March 2-4° below, and April 2*2° above the average. 



As change of temperature is at the root of all meteorological 

 movements there must be some great significance in this, if only 

 we could discover what it is.

WIND. 



It will perhaps be interesting to some persons to compare the 

 returns of the prevailing directions of the wind in the accompany- 

 ing table with the results obtained by ten years careful observa- 

 tion in the neighbourhood of London. From these observations 

 it appears that in that localitj^ the wind blew on an average from 

 the north on sixteen days, the south on eighteen days, the east 

 on twenty-six diiys, the west on fifty-three dnys. the south-Avest
