and 3—4 inches broad), and the crenulate, not serrated edge of the leaf. 
The allied P. balsamoides is found besides at Schosnitz in Silesia,* at 
Lausanne in sandstone, and in the marl of the tunnel near Neftenbach 
and Rorbac on the Jechel ; also on the Albis in Switzerland, and in white 
marl, near Giinzburg on the Danube. On the other side there is 
merely a fragment, unfortunately, of a leaf, which reminds us of Ju- 
glans, resembling J. acuminata by its lateral veins, which are connected 
by sunken, nearly rectangular veinlets. 
b. A specimen of Taxodium dubium in a younger and older stage, 
and with very perfect branches: a strikingly blunt-leaved form which, 
though there already exist numerous representations of the plant, de- 
serves to be figured. 
B. Older Formations. 
I regard in the collection before me, as not belonging to the Tertiary 
formation, No. 94, a rather hard, grauwacke-like specimen, here and 
there with parallel-striped, but not jointed imprints, with an anthracite 
covering, gathered on the north-eastern bank of the Aliiksa peninsula, 
north of Jaklek, on the southern shore of a rivulet ; also six specimens 
sent, sub No. 143, three of which also are in grauwacke-like rock; two 
resemble Calamites, one, a fern-stipe having lost its leaflets ; two in black 
schist, with tale-like, shining leaves, probably fragments of Sigillaria

count of its difference from all Tertiary floras then known,

discovery of an undoubtedly antediluvian tuff, in the Schosnitz deposits, pro-

Silesia had hitherto been met with exclusively in the diluvium, but more recent] 
in two places at a depth of six and sixteen feet in Liguite clay, was T rded by me 
on account of its great similarity to the
