refls over the furface. It is here noticed, to prevent errors in 

 experiments derived from fuch fituations ; and to fhew, in general, 

 the unfitnefs of great cities for determining, with accuracy, the 

 true temperature of the year ; in which places, neverthelefs, 

 experiments of this kind have ufually been made, without any 

 corredion for fuch irregularities. 



The local difpofition of our ifland, confiderably advanced 

 into the Weftern Ocean beyond the other fhores of Europe, and 

 removed from the immediate influence of any great trad of 

 mountainous country, renders it peculiarly fitted for a ftandard 

 fituation, to which the obfervations of other countries may be 

 conveniently referred, for which reafon thefe experiments have 

 been made with attention. 



The thermometers ufed were graduated from a common 

 ftandard ; and that ftandard itfelf carefully made, and compared 

 with many of the beft thermometers of different countries ; yet 

 ftill I would advife that the refults be not too implicitly confided 

 in, until fupported by fucceeding experiments.
