trunks or branches. The central portions of tlie stem are well 

 preserved ; but the outer part is soft and partially destroyed. 

 A has well-developed annual rings, some of the rings near the 

 periphery of the stem being, however, small and feebly developed, 

 thus indicating a deficiency in growth. The wood of B pre- 

 sents the same general characters ; and I am inclined to consider 

 them portions of the same species of Finns, if not parts of the 

 same tree.

 woods were obtained.
