lepideus, Fr., which Mr. Dudley has found attacking Pinus palus- 
tris, Mill., and P. mités, when these are used for ties, bridge 
timber and cars. Polyporus versicolor, Fr., also is very com- 
mon on white and red oak and chestnut, attacking the sap-wood. 
P. applanatus, Fr., has only been identified on the heart-wood of 
white oak, though common on the sap-wood of many other trees.

Lenticular Markings of various Contfere compared. J. L. Zabris- 
kie. (Journ. N. Y. Micros. Soc., i., pp. 218-220.) 
Mr. Zabriskie finds the largest lenticular cell-markings in wood 
of the Sugar Pine (Pinus Lambertiana, Dougl.), where they are 
about one one-thousandth of an inch in diameter. Among the next 
largest are those of Pinus palustris, Mill., Sequoia sempervirens, 
Endl., S. gigantea, Dec., and Pinus ponderosa, Dougl., while the. 
smallest noted are from the western Arbor Vite (Zhuja gigantea, 
Nutt.) these being but one two-thousandth of an inch across. 
He remarks that the number of markings in a certain length of 
cell bears an inverse ratio to their size.
