METEOROLOGICAL OBSERVATIONS, 



MADE IN THE TOWNSHIP OF CRUMPSALL, 

 FROM 1821 TO 1828, INCLUSIVE, 



REMARKS. 



BY JOHN BLACKWALL, F. L. S. 



(Read October 20th, 1826.*) 



Considering the greatly increased atten- 

 tion which of late years has been bestowed upon 

 atmospherical phenomena, it is mortifying to 

 reflect how little has been done, the important 

 discoveries of one or two distinguished indivi- 



* It may be proper to state, that when this paper was read 

 before the society, it comprised a series of meteorological obser- 

 vations made during a period of five years, commencing with 

 1821, and terminating with 1825. In its present form, the series, 

 with the exception of the observations on the temperature of 

 spring-water, and on the dew-point, which were discontinued, is, 

 with the permission of the society, extended to the close of 1828. 

 This circumstance will serve to explain the apparent incongruity, 

 into which it might be supposed I had been led, of having an- 

 nounced facts previously to the date of their occurrence.
