ence is, that when the thermometer of pro- 

 feflbr Celjius rofe to thirty cleg, above the 

 freezing point once in two or three fummers 

 at Aobo, the fame thermometer did not only 

 for three months together Hand at the fame 

 degree, but even fometimes rofe higher ; 

 not only in Penfyhania, but likewife in 

 New Tork, Albany, and a great part of Ca- 

 nada. During the fummers which I fpent 

 at Philadelphia, the thermometer has two 

 or three times rifen to thirty-fix deg. above 

 the freezing point. It may therefore with 

 great certainty be faid, that in Penfyhania 

 the greateft part of April, the whole May, 

 and ail the following months till October, 

 are like our Swedijh months of June and 

 July. So excerlive and continued a heat 

 mufl certainly have very great effects. I here 

 again refer to my meteorological obfervati- 

 ons. It muft likewife be afcribed to the 

 effects of this heat that the common melons, 

 the water melons, and the pumpions of 

 different forts are fown in the fields with- 

 out any bells or the like put over them, and 

 yet are ripe as early as July ; further, that 

 cherries are ripe at Philadelphia about the 

 25th. of May, and that in Penfyhania the 

 wheat is frequently reaped in the middle of 

 June.
