Forest Trees. — Professor Biisgen, of the Eisenach Forestry 
School, has recently published a handbook of information concern- 
ing the structure and life processes of forest trees,’ which are con- 
sidered as to their winter aspect, the causes of their forms, buds, 
tissues, wood and bark structure, annual or growth rings, formation 
.of heart wood, leaves, root activity, uses and source of water and 
mineral matters, metabolism and the transportation of food, fructi- 
fication and germination. The illustrations, many of which are 
original, contribute materially to the elucidation of the Ee ae dis- 
cussed. 
The Work of Aldrovandus.—In December last the city of 
Bologna celebrated the opening of a hall commemorative of one 
of her first botanists, and the proceedings on that occasion, accom- 
panied by an analysis of his works, form an attractive octavo pam- 
phlet ® which has recently been published.
