Puy Graveneire was liot the only instance that occurred to me 
in Auvergne, of a basalt agreeing in character with those of 
Scotland being associated with a rock possessing a vesicular struc- 
ture, and that I have at present in my possession more than one 
specimen which places this matter beyond doubt. 
The Puy Graveneire is also remarkable, inasmuch as, not- 
withstanding the strong indications it presents of having been 
in a state of ignition at a comparatively recent era, no trace of 
its crater can be detected, nor has it that abrupt and conical 
form so characteristic of volcanic hills, being rather a long, 
round-backed eminence, rising abruptly indeed on two of its 
sides, but to the north connected with the chain of the Puy de 
Dome, and to the south gradually sinking into the plain of Cler- 
mont.

During my last visit to Santiago, to convey A and 
Lady C~ to Valparaiso, I employed my first leisure hours 
in drawing up the following paper. I shall introduce the de- 
tail in regular order, previously hinting my opinion that a 
large Southern Continent is about to be discovered. The 
existence of this continent was believed many ages since ; the 
ancient, and many modern philosophers being fully convinced 
that a vast tract of land must lie within the limits of the 
Antarctic Circle, to which they gave the name of Terra Aus- 
tralis Incognita. Many were the speculations of the inge- 
nious on this subject, but perhaps none were more highly 
pictured in imaginative colours than those of Maupertuis 
(in his Letter to the King of Prussia), who pour tray ed a 
continent far larger than any of those known to us, where
