198 M. Rozet on the Life and Writings of 
its marbles, present also the same rocks ; that a long band of 
the jurassic and chalk formations extends along Carniola and 
Albania as far as the Gulf of Lepanto ; that the tertiary for- 
mation is developed in the Thracian Chersonesus, as also in 
the islands of Lemnos, Imbros, Samothrace, and Tenedos: fi- 
nally, that numerous traces of recent eruptions are to be seen 
in the islands of the gulf of Athens, nearly all of which are 
voleanic. 
For his geological description, Boblaye drew up a map on 
a scale of ss5ie50, reduced from the great map of the Mo- 
rea, in six sheets, published by the War Department. This 
map, coloured geologically, in concert with M. Virlet, is en- 
titled, ‘‘ Map of the Morea and the Cyclades, representing 
the principal facts of ancient geography, and also of natural 
geography.” It is accompanied by a learned memoir, en- 
titled “‘ Geographical researches on the ruins of the Morea.” 
This memoir comprehends all the information that resulted 
from the labours of the members of the scientific expedition 
and the officers employed in constructing the map, respect- 
ing the topography of the ruins of the ancient Peloponnesus. 
This remarkable work, which would have opened the doors of 
the Academy of Inscriptions to our colleague, if he had lived 
longer, cost him three years’ researches in the works of anti- 
quity and those of the middle ages, and in the writings of 
modern travellers. It makes us acquainted with the boun- 
daries of every state, and of every province; and furnishes curi- 
ous details respecting the towns, and all the ruins which time 
and the hands of barbarians have not entirely swept away. 
On his return from Greece, Boblaye read to the Society a 
memoir entitled, “ Notice respecting the alterations produced 
on the calcareous rocks along the shores of Greece by the 
action of the sea.’* The new and original observations em- 
bodied in this essay, tend to fix the principles by which we 
may recognise the traces of ancient sea-beaches in the inte- 
rior of countries. 
Having been elected secretary to the Geological Society in 
1834, he made a very remarkable report on the works of the 
* Bulletin of the Geological Society of France, t. i., p. 150; and 
Jameson’s Journal.
