The shales were very rich in impressions of plants, and I col¬ 
lected a great variety, which will enable the paleontologist to 
determine by what plants these huge coal deposits were princi¬ 
pally formed. The greatest part are leaves of dicotyledonous plants, 
in a high state of preservation, and often several inches long and 
broad; but I found also portions of plants belonging to the families 
Cycadese,Brachyphyllum,Calamites,and Zamites. I only discovered 
one fern, allied to Pecopteris, and one Equisetum; and we may 
therefore infer that we have rather to do with the remains of 
extensive forests than with those of swampy or rushy grounds. 
In the shales and sandstones belonging strictly to these coal 
measures I could not detect any fossils, but in the arenaceous 
limestone (or rather calcareous sandstones) overlying them I met 
with some exuviae belonging to the genera Monotis and Serpula. 
In the clays D, I obtained a better harvest. Here I met with 
numerous bivalve shells from acephalous mollusks, as well as from 
brachiopods, amongst which the genera Monotis, Posidonomya, 
Inoceramus, and Terebratula occur ; gastropods are also abundant, 
amongst which small species of Eusus and Murex were the most 
numerous. I found, too, a small Echinus, but unfortunately in a 
very fragmentary condition. The absence of cephalopods is very 
striking, and we may conclude from it that these strata were 
deposited in shallow or muddy waters not frequented by belem- 
nites, ammonites, &c. As soon as the specimens collected by me 
have been described by an able paleontologist, I will make the 
result of this investigation known to you. 
The coal-bearing strata are covered for seven miles near the 
coast line by cretaceous rocks, of which I shall speak after having 
completed the description of the former. Where these cretaceous
