320 Meteorological Obfervations. 



Before I went to Canada in fummer 

 1749, I defired Mr. John Bartram to make 

 fome meteorological obfervations in Pen- 

 Jylvania, during my abfence, in order to 

 afcertain the fummer-heat of that pro- 

 vince. For that purpofe, I left him a 

 thermometer, and inftructed him in the 

 proper ufe of it -, and he was fo kind as to 

 write down his obfervations at his farm, 

 about four Englifo miles to the fouth of 

 Philadelphia. He is very excufable for not 

 putting down the hour, the degree of 

 wind, &c. for being employed in bufinefs 

 of greater confequence, that of cultivating 

 his grounds, he could not allow much 

 time for this. What he has done, is how- 

 ever fufficient to give an idea of the Pen- 

 Jyhanian fummer.
