264 STUDIES IN SEEDS AND FRUITS 

 III. BERRIES, DRUPES, etc. 



Note, The total amount of water in these fruits can readily be ascertained by applying 

 a small correction to the loss sustained when dried in air. As a rule the air-dried fruits 

 would lose between 10 and 15 per cent, of their weight when exposed to a temperature 

 of 100 C. The corrected result for the air-dried berry of Tamus communis ; assuming 

 that it lost 12 per cent, of its weight in the oven, would be as follows : 



Moist weight .... 100 

 Air-dried weight . . .18 

 Oven-dried weight . . .16 

 Loss when air-dried ... 82 

 Loss when oven-dried . . 84
