results derived from the voyage of the ' Challenger/ the second a 

 sketch of the Geology of Now Caledonia. The following formations had 

 been recognized, chiefly by means of fossils : — Quaternary, with species 

 still living ; L. Neocomian ; U. Lias, with Nucula Hammeri ; L. Lias, 

 with Ostrea suhlamellosa, &c. ; U. Trias, with Halohia Lomelli ; L. 

 Trias, with Pellatia Garnieri ; U. Devonian and U. Silurian ; Azoic 

 (mica-schist). The most important formation appears to consist of 

 eruptive magnesian rocks, in which are found the deposits of chromic 

 iron -ore and the nickel mineral for which the island has become cele- 

 brated. Specimens of the nickel mineral were forwarded to Prof. 

 Dana, who accepted Mr, Clarke's name, " GarnieriteJ' E,. E., Jun.

S. of the harbour of Takao a fossiliferous limestone occurs ; a part 

 containing Monotis Hawni may be Permian. At Kao Siah occurs slate 

 which would probably make a good building material. R. E., Jun.

Workable deposits have been found at Kanala, along the Dumbea, 

 and the Huantio and elsewhere. The ore occurs in masses, nodules, 

 and more or less impregnated beds, not in veins. G. A. L.
