high walls and buildings. Yet in the Museum garden we have 

 for 12 months 23°785 inches of rain, and Mr. J. Gray's results 

 for the same period are 2o"020. (The snow which fell in this 

 period is excluded from both these numerical statements.) Tlie 

 depth of rain appears pretty nearly uniform over the broad 

 vale of York, and even beyond it. Thus at Ackworth, 25 



miles S.W., the quantity collected in 1832 =24*94 



At Brandsby, 12 miles N. (station nearly level with the 



top of York Minster) 25-65 



At York 23-78* 



4. I shall now proceed to arrange the numerical results of 

 the experiments, in relation to mean temperature and the 

 season of the year, and thence to infer the ratios of quantity 

 at the several stations. The quantity of snow which fell is 

 always deducted, because it was found to drift into the lower 

 gauge. This quantity was, however, very small and only sen- 

 sible in February 1833. 



• In 1833, The Museum gauge gave 22-959 inches.
