Inspection of Table IE shows: 
1. That all four specimens absorbed water very slowly just 
after they were freshly cut, and that the rate of absorption was 
greatly increased after they had lost weight by remaining over night 
in the dry air of the laboratory. 
2. The rate of absorption showed a correlation with extent of 
leaf surface, being considerably greater in the two specimens with 
large extent of leaf surface than in the other two. 
3. The weight lost by drying for a given period was nearly or 
quite regained when the leaves were given a full supply of water 
for a corresponding length of time. The capacity of this species 
for leaf absorption, under the conditions described, is thus fully 
demonstrated. Its deportment in the seedling stage, which offered 
for experiment perfectly fresh and unmutilated material, will next 
be considered. 
Seedlings of Celtis pallida were grown from seeds sown Novem- 
ber 14, 1904. When used for experiment in January and February,
