quent deportment of the seedling indicates that their failing condi- 
tion previous to removal may be disregarded as not materially 
affecting the results. As the table shows, the weight of the whole 
plant above ground, including cotyledons, was less than the weight F 
of water transpired in 19 hours (Feb. 14-15) and also less than the 
gain of weight by absorption in 26 hours (Feb. 16-17), a conclusive 
proof of the relatively large quantities of water absorbed and trans- 
pired by this seedling during the period of experimentation. The 
facts regarding seedlings 4 and 5 are so fully set forth in Tables VI 
and VII as to render further explanation unnecessary. |
