Hi 





With regard to the influence of local situation in aug- 

 menting or diminishing the quantity of rain, I have little 

 information to give. The highest station in the preceding 

 list of places is that on Lead Hills, and there the quan- 

 tity of rain is below the average for the western counties ; 

 while from some measurements on the line of the Roch- 

 dale Canal it would seem that the high ground receives 

 more than the low and open country, but that when sur- 

 rounded by hills the low ground receives as much, or 

 more than elevated places. The following are the quan- 

 tities, as given in the Memoirs of the Literary and Philo- 

 sophical Society of Manchester : —
