A volcanic chain stretches along the boundary-line between the two 

 parts of the island, with the so-called volcano of Labo, and the Sierra 

 de Colasi, both composed of homblende-andesite. At Hagay this rests 

 on a highly fossiliferous limestone. The lavas of Labo rest on crystal- 

 line schists, which appear to form the ground mass of the island. 

 Quartz -reefs occur in the schists rich in lead-glance, zinc-blende, 

 gold, and covelline. Coralline limestone is also found. 11. L. J.

The earliest eruptions at Bourbon (Reunion) were submarine, and 

 consisted of trachytic and andesitic lavas, with gabbro-like rocks ; ba- 

 saltic lavas, rich in olivine, were ultimately erupted, and the cone rose 

 above the sea-level. The volcanic history of the island is traced in 

 detail. Believes that Mauritius represents a volcano which was once 

 much larger, and argues against a former connexion of Bourbon and 

 Mauritius. P. W. R.

 Observation in discussion. The rocks of the island (besides volcanic 

 deposits) are U. Cretaceous and Eocene. No Pliocene beds occur.

 The following succession of strata is given : — 1. Limestone, with 

 Fusulina, Crinoids, and Euomphalus : Carboniferous. 2. Marl-shale, 

 with abundant iish-remains, Fistidaria, Osmeroides : U. Cretaceous or 

 L. Tertiary. 3. Sandstone, with coal seams and carbonaceous shales : 

 unconformable to 2 ; plant remains and Melanice. 4. Marl sandstone, 

 with Ostrea, Pecten, and Serpula. 5. Upper (Coral) Limestone, with 

 casts of Mollusca, Echinids, &c., Eocene. 3, 4, and 5 are correlated 

 with the three divisions of the Eocene of Borneo. Por Paljeontologt
