1870. ] _ COUMBARY—FALL OF AN AEROLITE, 415 
As to the supposed Hozoon, he had not been able to recognize any of 
the characteristics of that fossil; and by treating the Trinidad spe- 
cimens with acid, he found no traces of structure left, and yet there 
had not been sufficient metamorphism to destroy other organisms. 
In some dredgings from the Atgean Sea he had found fragments of 
echinoderms and other organisms, in which a siliceous deposit had 
replaced the original sarcode in the same manner as had occurred in 
the Canadian Hozoon, thus proving the possibility of this form of 
substitution, which had been warmly contested. 
Mr. Tare offered some suggestions as to the age of these beds, 
which were certainly older than Neocomian. The Californian gold- 
bearing beds appear to be Jurassic. Similar beds occurred in New 
Mexico, Guatemala, and were observed by him in Nicaragua and 
Costa Rica. These present lithological and mineralogical affinities 
to the Venezuelan and Trinitatian metamorphic series, and were 
conjectured to be of the same age. 
5. On the Fall of an Arrouire in Fuzzan. By M. Coumpary. 
(Communicated by R. H. Scott, Hsq., M.A., F.G.8.) 
[ Abstract. ] 
Tue object of this communication was to describe the fall of an 
aérolite or bolide, which took place on the 25th December, 1869, at 
Mourzouk, in Fezzan (lat. 26° N., long. 12° E. of Paris), in the pre- 
sence of a group of Arabs. The bolide is described as a globe of fire 
nearly a metre in diameter, which, on falling, exploded with a sound 
resembling pistol-shots and a strong odour. 
It is further stated that the whole or portions of the bolide will be 
forwarded—and that, according to information given, the poignards, 
sabres, and lances of the principal people of Waddai are constructed 
of meteoric iron, much of which has fallen in that district.

The following communications were read :— 
to) 
1. A letter from Dr. Gerard Krefft, dated Sydney, 29th January, 
1869, accompanying a model of the left lower incisor of Thylacoleo 
carnifex, Owen, as restored by the author, and a cast of the original 
fragment which enabled the model to be made. Dr. Krefft referred 
as follows to the fossil remains of Herbivorous Marsupials in the 
Museum at Sydney :— 
“There is a very fine series of fossil remains in the Australian- 
Museum collection, and very many of the specimens yet unde- 
termined.
