II. — Pear (Bartletl). 



The first three samples were tested when taken from the 

 tree. The fourth was picked Sept. 7, and tested two weeks 

 later : after hanging during this time in the ordinary atmos- 

 phere of a common room, it was found to have lost from 

 seven to eight per cent in weight, and gained thirty-three 

 per cent of sugar. 



THE CRANBERRY. 



The specimens of the cranberry which served for this test 

 were furnished by parties engaged in their growth, and desir- 

 ing to know the relative proportion of the essential elements 

 of plant-food, for the purpose of determining what to return 

 to the soil. 



The following tables give the analyses of the fruit two 

 weeks after harvesting.

No cane-sugar was found ; and the acid, probably, was of 

 two kinds, — citric acid, or the acid of the lemon, and malic 

 acid, or that of the apple.
