OBS. 6. The incifion, one foot from the ground, bled in the even- 

 ing, more than an hour after the two incifions above it were 

 dried up. 



OBS. 7. This day, the bark would not peel off the young 

 branches of the tree ; but the epidermis feparated more freely 

 from the bark than formerly. 



MARCH 15. 

 Thermometer, at noon, 52. j at midnight, 44. 



Thermometer, at noon, in the fun, 67. 

 THE fifth incifion, four feet high, bled for the firfl time; but 



the fixth incifion, and all above it, ftill refufed to bleed ; yet the 



fixth was more moifl than formerly, efpecially between wood 



and bark. 



OBS. 8. It was now found, that the incifions did every day ceafo 

 to bleed upon the removal of the fun, the uppermofl giving 

 over firft, and the reft fucceflively downwards. The fap had 

 now rifen in the tree to the height of four feet. The fifth 

 incifion ceafed to bleed this day at three in the afternoon. 

 The four incifions below it gave over bleeding one after ano- 

 ther, and were all dry at five o'clock ; the fun having become 

 clouded, and the thermometer fallen to 44. 



MARCH 16. 

 Thermometer, at noon, 47. ; at midnight, 37. 



THE five loweft incifions bled as on the former day ; but the 

 fixth ftill continued dry. 

 COR. 2. It appears, that the fap will not rife much higher by 



the heat of 47. than it did on the preceding day by the heat 



of 52. but will maintain its afcent, and bleed at the fame 



height*
