CLIMATOLOGY. 



85 



hiberno-asstival difference of from 20 to 233 and, taking 47 as the 

 most likely basis to calculate from, estimate the temperature of 

 the Lower Zone at from 44 or 45 to 47 or 47}^, of the Middle 

 Zone at from 41 to 44, and of the Upper Zone at from 39 to 41. 



According to the observations of Mr. Abbey, made day by 

 day during i860, at Horton Hall near Bradford, as compared 

 with the mean temperature of the air in the shade at a height 

 of 4 feet from the ground, the mean temperature of the air in 

 the shade at 8 feet was i degree, at 6 feet 0*5, at 3 feet o"8, at 

 2 feet 2'i, at I foot 2*9, and upon the grass 4 degrees, in all 

 these instances lower, and at i foot below the surface i'6 

 higher. 



Maxima atid Minima in the Shade. — Under this head a 

 table giving the highest and lowest temperatures registered in 

 our own district and in other localities at the same time, will, 

 I think, be more satisfactory than to take them as observed at 

 different times. For the maxima I have taken the summer of 

 1859, for the minima the winter of i860.
