Commandant E. le Puillon de Boblaye. 197 
that cruel disease which eventually deprived us of him alto- 
gether. From a desire of seeing as much of the country as 
possible, he would not submit to follow the convoy which 
transported the instruments and baggage. Hastening for- 
wards, he arrived alone, very much heated, on the moun- 
tains, and immediately began to examine the country with his 
telescope. Soon the cold seized him; and this imprudent 
act, very often repeated, at last brought upon him a severe 
fever. Numerous successive attacks of this kind often ob- 
liged him to interrupt his labours. At last the disease made 
such progress, that, in the month of August 1830, Boblaye 
was compelled to leave the Morea and return to France. It 
was now upwards of sixteen years that an individual so dis- 
tinguished had been connected with scientific works of high 
importance, during which enlightened views and remarkable 
memoirs had va indicated his genius, and yet this indi- 
vidual had only attained the rank of Captain, so peculiar was 
the organization of the body of geographical engineers. 
Although he did not remain above sixteen months in 
Greece, our colleague brought back with him an enormous 
mass of materials. He assisted in the great work published 
under the direction of Colonel Bory de Saint Vincent, and 
drew up, in connection with M. Virlet, the geological and 
mineralogical portion.* M. Boué has said :+—** Our fellow 
members, MM. Boblaye and Virlet, cannot be sufficiently re- 
warded for the valuable present they have made to science 
at the expense of their own health. M. Boblaye introduces 
the geological description of Greece by a survey of the re- 
cent progress and present state of geology. In this sketch, 
we perceive the touch of a skilful geographer and geologist, 
who searches for truth above every thing else with the cool- 
ness of a mathematician.” We have learned, from the publica- 
tion of our colleagues, that Olympus and Pindus are composed 
of granite, gneiss, and mica-slate, of tale-slate and granular 
limestone ; that Attica, Mount Athos, the Chalcidie Cherso- 
nesus, the mountains of Macedonia, and the isle of Thaso with
