Lacustrine Formation of Torryburn V alley. 1 5 
their belonging to a species not unconmioii in that region (North- 
Eastern North America), N. megacarjya, Allen, (Eigs. 7 — 11). 
Xote 3. — The lai'ge black seeds may be classed in three groups, 
the long and rather narrow, with sharp angles, (Figs. 12 — 18), the 
broadly oval (Figs 19 and 20), and the oblong with very faint striae 
(Figs. 21 and 22). The first group has the characters of C.fragilis’ 
Desv. ; the second of C. intermedia^ A. Br. (now living in the lake), 
and the third cannot be determined accurately ; possibly it may be 
a form of the latter class. 
Note 4. — We do not discover any progressive change of form in the 
nuclei from diflferent numbers (or divisions of the lacustrine deposit), 
nor any characters which would lead us to suppose any of the nuclei 
to belong to extinct species. The first form {C. coronata. probably) 
has no exact counterpart among our existing species, but they are 
not well known.” 
NOTES ON THE LAND FLORA AND FAUNA. 
Scattered through the various members of the lake deposit, but 
more particularly abundant in the Clay, are fragments of wood, 
bark, cones of evergreen trees, bud-scales and leaves, and fruits of 
several species of Land plants. Among the earliest determinable 
objects of this kind are the leaves of the American Fir [Abies hal- 
samea): these leaves were not found plentifully, and are smaller than 
the average of leaves of the firs now living in the neighborhood. 
This species was not found so low down in the deposits of Lawlor’s 
Lake as in those of the Eastern Basin. 
The seeds of the European Cranberry (the small marsh cranberry) 
{Vaccinium oxycoccus), has a wide range through the deposits of 
Lawlor’s Lake, but is less plentiful in those of the Eastern Basin. 
It was very plentiful throughout the layers of Div. 2, having first 
appeared in Division No, 1. Throughout Nos. 3, 4 and 5, it is also 
found, but above this becomes scarce. The appearance of this 
species among the first in the lake deposit is quite in accordance 
with Nature’s provisions for its propagation, — namely : the tough, 
impervious skin of the fruit, the floating air-cells of the pulp, the 
hard nut-like covering of the embryo, tkc. 
In the Eastern Basin the remains of the Black Spruce {Abies 
nigra.) were found at a lower level than in the deposits of Lawlor’s
