“The domestic animals here, are the cow, ox, sheep. goat, 
dog, cat, horse; and the wild, are tigers, jackalis, foxes,

11. Difficulty of Mineralogical Excursions in Spatne— 
*““] have been much disappointed by being prevented from 
executing my mineralogical excursions in Spain, by the 
bands of powerful robbers, that have long infested the as- 
tonishingly extended surface of uncultivated and uninhab-

of specimens from an ancient volcanic field, four miles 
west of Humilla, in the province of Murcia. It appears 
to be an ancient lava, with the vacancies filled with the 
crystals of phosphat of lime, called by Werner, Spargel- 
stein. This lava crops out from under an old secondary 
compact limestone, containing shells ; and probably arose 
from a submarine volcano, or was afterwards covered by 
the sea, to a considerable depth, and for so long a time, as 
to allow limestone mountains, full of shells, to be formed 
over it.”’ 
13. Opinions as to the Principal Rock Formations.—“As 
the result of ail that ] have seen, I am confirmed in the 
opinion, that the Neptunian and Volcanic formations, of 
the four classes, that cover the primitive, have been pro-
