METEOROLOGY. S47 



of attending to the phenomena which these instru- 

 ments indicate, in the vicinity of their different 

 places of abode. These records have already been 

 useful ; but, by continuing to register their obser- 

 vations upon the atmospheric changes, until a suf- 

 ficient number shall be obtained, they will confer 

 an important obligation on the generalizing meteo- 

 rologist, and contribute to the advancement of the 

 science of the atmosphere. 



Among philosophers, Mayer, Kirwan, Hutton, 

 Franklin, Playfair, Leslie, Wells, Forster, Halley, 

 De Luc, Fontana, La Place, Humboldt, D'Alem- 

 bert, and numerous others, have laboured in the 

 science of meteorology with various credit and suc- 

 cess. Among these, Professor JNlayer has given us 

 a formula for determining the temperature of any 

 situation on the globe, where observations have not 

 been made. Dr Hutton has presented us with a 

 theory of rain, ingenious and plausible, and calcu- 

 lated to explain some phenomena, which could not 

 before be accounted for, on any allowed principle. 

 Kirwan, Humboldt, and others, have advanced our 

 knowledge of the climates of different countries, by 

 their laborious researches on atmospheric tempera- 

 ture. Dr Wells, by his investigation of the phe- 

 nomena of dew, has accomplisjied a most interesting 

 result in the discovery of the cause on which its for- 

 mation depends. Professor Leslie, by the invention 

 of several curious and useful instruments, and by his
