The following table, contributed by Mr. T. W. Backhouse, of 

 West Hendon House, Sunderland, gives the result of observa« 

 tions made daily at frequent intervals. It will be seen from it 

 that, as far as observed, the greatest proportion of rain fell with 

 the wind from S.E., at Hendon, in 1871, which, Mr. Backhouse 

 remarks, is unusual. 



Duration, in hours, of Wind, from each Quarter, at Hendon, in 1871, 

 with the amount of Rain which fell with each, and the Yearly Ratio 

 of the same.
