Possible XcK' Coal-PIanfs Etc., in Coal. — Gresley. 7 
character of the enclosing material, being rather dull and 
gray, or "bony," than black or more glossy coal. 
Notice how easily the lower part of the specimen fig. i 
might be mistaken for the form illustrated in fig. 3, plate II, 
facing p. 50, vol. xxvi, July, 1900. 
Fig. 4. Vertical view showing a patch of ? detached or scattered 
tii-radiate spores,? occurring in coal same as fig. i. 
Fig. 5. Longitudinal section, ? somewhat oblique, apparently ex- 
hibiting a small cone or inflorescence belonging to some 
unknown plant embedded in a dark gray lamina of Penn- 
sylvania anthracite. 
Reference to plate III and remarks on the specimens. 
Figs. I to 7. Horizontal, or for the most part horizontal, sections of 
various pods, seeds, infloresences etc., of several kinds at- 
tached to or in such close contact with parts of stalks, twigs 
or other extremities of plants that they are probably in situ. 
Observed upon the planes of lamination of various speci- 
mens of Pennsj-lvania anthracite.

parently attached at the junction of ribbon-shaped processes.

Fig. 10. Exterior of macrospore ? (in this case composed of py- 
rite) embedded in anthracite ; associated with several other 
scattered ones composed of coal. The shape of this fossil 
seems peculiar. 
Note. If we admit that for the most part those fossils 
are fragmentary all that I care to say concerning them is that 
we seem to be presented with some five or six different spe- 
cies of seeds and ovules, as the case may be, none of which 
seem to belong to cones, but rather to meandering, swelling, 
branching and sinuous plants. However this may be, these 
drawings may serve to direct the attention of other workers 
to similar forms, so that eventually their significance may ap- 
pear. Since some layers or horizons of the anthracite are 
quite crowded with this kind of forms, the plants to which 
they belonged were decidedly coal-forming in their nature, 
or as to their substance. 
Reference to Plate I\', and remarks on the specimens.
