111 the strata of Vegetable Creek fruits have been found (Fig. 22, 
Fig. 22a magnified) very much resembling those which I have collected at 
Schoenegg in Styria (Austria). They are very small, rounded, fiat, and 
surrounded by a narrow and very thinly membranaceous wing, and show all 
the characters appertaining to the single fruits of an Alnus. 
Locality and Horizon . — Fox and Partridge’s claim, between Rose 
Valley and the Red Hill, 2 miles from Emmavillc (Vegetable Creek Town- 
ship) ; ironstone shale from the Newer Leads (stanniferous) below basalt. 
Newstead, near Elsinore ; in concretionary ironstone (earthy limonite), asso- 
ciated with basalt.

Ohs . — An extremely well-preserved fossil, from Vegetable Creek, 
showing the under surface of the leaf, and exhibiting thereon, when examined 
through a strong glass, even traces of the epidermis cells. The leaf bears a 
comparatively short (G millimeter long) petiole ; the lanceolate lamina is very 
little narrowed at base, but much more gradually so towards the apex. The 
borders are somewhat thickened. The consistence of the leaf is coriaceous 
and stiff. The numerous secondary nerves, being curved and rather flexuous, 
are anastomosing before the margin. The tertiary nerves proceed from the 
primary in every secondary segment, two or three at nearly right angles. 
One of these is stronger, and often transforms into a short secondary nerve. 
The other tertiary nerves diverge from the outer side of the secondary at acute 
angles, and anastomose, thus forming a tolerably strong network. The latter 
is filled out by a very fine net of the quaternary and quinternary nerves (see 
Fig. 16a, enlarged).
