during which its several volcanic fonnations originated, we find the 

 closest analogy between the island of Ischia and the adjacent Campi 

 Phlegrsei ; and the study of the former throws much light upon the 

 structure of the latter. 



In Ischia we see proofs of a great volcanic cone rising gradually 

 above the sea-level, and, when it had reached its present limit of size, 

 becoming extinct, while lateral outbursts took place on its flanks. 

 Finally, around the ruins of the central pile, sporadic erup- 

 tions gave rise to smaller cones and craters, and even these in 

 some cases had their lateral or parasitical cones. The points of 

 resemblance and difference in the course of events and the succes- 

 sion of products in the three great volcanos of southern Italy — 

 Epomeo, Vesuvius, and Vultur — are worthy of the most attentive 

 study and consideration at the hands of the geologist.

1872, December 12th, 453, p.m. — Lexington, Kentucky. 1 



The meteor took a direction S. 45° E., and exploded with a loud 

 noise at an altitude of about 20 miles, the cloud remaining 

 several minutes. The . inclination to the horizon was probably not 

 less than 30° or more than 60°. The fragments of the meteorite, 

 which have not yet been found, probably fell 20 or 30 miles N.W. of 

 Lebanon. 



A number of meteorites have fallen about this date, and they are 

 separated in a group by an interval of some days from the aerolites 

 of the earlier and later days of December. The members of this 

 group are : — 



1858. December 9th. Aussun and Clarac, Haute Garonne, France. 



1870. December 9th. Tjabe, Bodgo Negoro, Bembang, Java. 



1871. December 10th. Gcemorceh, near Bandong, Java. 

 1836. December llth.(?) Macao, Brazil. 



1872. December 12th. Lexington, Kentucky. 



1795. December 13th. "Wold Cottage, Thwing, Yorkshire. 



1798. December 13th.(?) Krakhut, Benares, India. 



1803. December 13th. Massing, Eggenfeld, Bavaria. 



1813. December 13th. Luotolax, Wiburg, Finland. 



1807. December 14th. "Weston, Connecticut. 



Found 1872.— Los Angeles, California. 2 



A very brief account is given of a mass of iron weighing 801bs., 

 which was found at Los Angeles. It is stated that its specific gravity 

 is 7-905, and that, when acted on with dilute nitric acid, the smooth 

 surface exhibits innumerable scales of schreibersite, but that the 

 usual figures are not developed.
