In addition to the woods of the deciduous trees enumerated in the above 
table, tests had previously been made of the wood of the gray birch (Betula 
populrifolia), of the willow (Salix alba), the popiar (P. tremultformis), and 
the so called leather wood or moose wood (Dirca palustris), with negative 
results in every instance. In the products of the hydrolysis of the wood of 
the sugar maple (Acer saccharinum), however, mannose was found. See 
Bulletin of the Bussey Institution, Volume III, pages 32 and 34. 
Tests of the products of the hydrolysis of certain leaves, other 
than those of pine trees, are set forth in the following list and 
table : — 
Red Clover leaves (7rifoliwm pratense). Collected at the Bussey Institu- 
tion on July 17, 1902. 
Apple leaves. Plucked from a tree at the Bussey Institution, September 
18, 1902.
