13. Not named 1850, Nov. 2 Gasparis, Naples Unk'wn

It appears that of these thirteen Asteroids, three have been discovered
by Hind of London, three by Gasparis of Naples, two by Hencke of
Driessen, two by Olbers of Bremen, while Piazzi of Palermo, Harding of
Lilienthal, and Graham of Markree, have each discovered one. Eight out
of the twelve orbits ascertained have an inclination of less than ten
degrees. The _London Athenaeum_ states that the Lalande Medal of the
Paris Academy of Sciences has been awarded to M. de Gasparis for his
discovery of the planet Hygeia. The prize for 1850 was shared between
Gasparis for his two discoveries in November, and Mr. Hind for his
discovery of Clio on the 13th of September.

GEOLOGY OF SPAIN.--A late number of the Journal of the British
Geological Society contains an interesting and valuable paper by Don
JOAQUIN EZQUERRA DEL BAYO, on the Geology of Spain. The Geological
constitution of the country is stated to consist of three principal
divisions--the Crystalline, Transition, and Secondary formations. The
gneiss rocks of the first division occupy about a fifth of the surface
of the soil, extending longitudinally from north to south. The plutonic
rocks which penetrate them are generally granite of various degrees of
firmness. The most important of the granitic ramifications to the east
passes by the Sierra de Gridos, Sierra d'Avila, and the Guadarrama, to
Soma Sierra, in a north-east direction. The great granitic outburst of
Truxillo and of the mountains of Toledo does not extend so far to the
east. A third, which has probably given its present form to the Sierra
Morena, terminates at Linares, in the province of Jaen. The rocks are
not rich in useful metals compared with their great development, but
lead and copper are found in great quantities in the district of
Linares, and rich argentiferous veins have been lately discovered at
Hiendeleucina. Other veins have become exhausted. The successive
formations of the country present some curious features. "Our soil,"
says Don Joaquin, "has never been at rest, nor is it so even at present.
Earthquakes are still often felt at Granada, and along the coast of the
province of Alicante, where their effects have been disastrous." Among
the numerous fossils found upon the coast of Spain are some species of
mollusca of an extraordinary size, a
