It may not, perhaps, be out of place to observe here, that, to 
complete this list of petrifactions of the different formations of 
Europe, it would be necessary, in the first place, to consult the 
general works on fossils, such as Knorr’s great and fundamental 
work, the Encyclopedic Methodique, Burtin, Lister, the Geologi- 
cal Transactions, Parkinson, &c.,and then to have recourse, for the 
different formations, in particular, to the following works : For 
the Transition Deposit, to Miller’s Encrinites, Sowerby’s Mineral 
Conchology, Wahlenberg’s Memoir on the Orthoceratites, Brong- 
niart’s on the Trilobites, and the Description of the Fossils of 
the Mountain Limestone of the United States, in Silliman’s 
flournal. For the Coal formation, a synonymy might easily be 
established between the works of Schlotheim (Flora der Urwelt), 
Sternberg, Nan, Martins, (Memoirs of the Munich Academy), 
Bhode, (4 Fasciculi of Fossil Vegetables, Breslau,) and Brong- 
niart’s Memoirs. This latter gentleman will commence, in 
spring, the publication of his great work on this subject, so 
that no department of organic remains will be so well known. 
For the lias and Jura limestone, Sowerby and some Parisian 
memoirs would, in particular, require to be examined. For the 
upper Jura limestone, and the chalk formation, the same au- 
thors, together with MantelPs work, Faujas on Mont St Pierre, 
Brongniart’s work on Paris, Desmarest’s on the Crustacea, would 
furnish ample materials. The fossils of the plastic clay would 
be found in Brongniart’s work on Paris, in Sowerby and Fer- 
russac ; those of the first tertiary limestone, and the other ter- 
tiary deposits, in Lamarck, Brocchi, Brongniart on Paris and on 
the Vicentin, in Sowerby, in M. Deshaye’s work already com- 
menced, in Borson’s Memoir on Piedmont, (Memoirs of the Tu- 
rin Academy), in a work which is soon to be published by M. 
Basterot on the fossils of Bourdeaux and Dax, and in Fichtel’s 
Transylvania. Lastly, Cuvier would furnish a complete list of 
all the animal remains of the alluvial formations ; and. Blain- 
,ville a catalogue of the greater number of known petrified fishes.
