METEOROLOGICAL REPORT, 1872, BY THE 



to introduce, what was needed to complete the view of the cli- 

 mate of our north-eastern district, a general table of the average 

 monthly amount of Cloud. 



The limited space at the disposal of the editors in the present 

 volume renders it necessary to omit all subsidiary tables, and also 

 many interesting Notes on Plants, Birds, Insects, &c. They 

 append, however, a few special tables of considerable value, prin- 

 cipally in continuation of similar records embodied in the Reports 

 of former years. 



The following particulars from the Observatory, Durham, have 

 been supplied by Mr. J. J. Plummer.

In the following, the figures for Alnwick are obtained by tak- 

 ing the mean between the greatest and least velocities, attained 

 by the wind each day, as the mean velocity of the wind for that 

 day. In the case of Durham the figures given are strictly exact.
