At Port Famine much of the clay-slate is calcareous, and passes either into a mudstone or into grauwacke, including odd-shaped concretions of dark argillaceous limestone. Ancyloceras simplex, d'Orbigny "Pal Franc" Mount Tarn. 2. Natica, d'Orbigny "Pal Franc" Mount Tarn. 4. Pentacrimus, d'Orbigny "Pal Franc" Mount Tarn. 5. Lucina excentrica, G.B. Sowerby, Port Famine. 6.
"It is just on that account that I have hopes; he has a young wife, she will be compassionate; and, besides, in the country one can do so much good. He will take you, I suppose, for housekeeper; I will take care of the linen. Since Lord d'Orbigny is very rich, in a large house there is always employment." "Yes; but we have so little right to his interest. We are so unfortunate."
These beds are the equivalents of the white chalk and chalk marl of England, or Senonien of d'Orbigny, although the white siliceous sands of the lower beds, and the green grains in the upper part of the formation, cause it to differ in mineral character from our white chalk. Beds of fine clay, with fossil plants, and with seams of lignite, and even perfect coal, are intercalated.
Hamites elatior, G.B. Sowerby, Port Famine. M. d'Orbigny states that MM. Hombron and Grange found in this neighbourhood an Ancyloceras, perhaps A. simplex, an Ammonite, a Plicatula and Modiola. Professor E. Forbes, judging only from my specimens, concurs in the probability of this conclusion. The Hamites elatior of the above list, of which a description has been given by Mr.
What this epoch may be, compared with the European tertiary stages, M. d'Orbigny will not pretend to determine. Some few of the species are closely related with existing ones; this is especially the case, according to M. d'Orbigny and Mr. Sowerby, with the Fusus Patagonicus; and, according to Mr.
Conceal yourself in some distant place; cause yourself to be forgotten; become Madame Pier re or Madame Jacques, and repent if you can.

I saw one of these heaps which was eight feet in diameter, and was composed of a large quantity. This habit, according to M. A. d'Orbigny, is common to all the species of the genus; it is very useful to the Peruvian Indians, who use the dung for fuel, and are thus saved the trouble of collecting it. The guanacos appear to have favourite spots for lying down to die. On the banks of the St.
One of its most striking features is its great extent; I passed continuously over it from the Colorado to St. Fe Bajada, a distance of 500 geographical miles; and M. d'Orbigny traced it for 250 miles further north.
These three lower beds are covered by an unconformable mantle D of stratified sandy earth, including many pebbles of quartz, pumice and phonolite, land and sea-shells. M. d'Orbigny has been so obliging as to name for me the twenty species of Mollusca embedded in the two gravel beds: they consist of: Volutella angulata, d'Orbigny, "Voyage" Mollusq. and Pal. 2. Voluta Braziliana, Sol 3.
Professor Forbes adds, that, possibly, internal characters may exist, which would distinguish the American species from its European allies. Spirifer linguiferoides, E. Forbes. M. d'Orbigny considers it as perhaps indicating the Jurassic period. Ammonites, imperfect impression of.
