rather, as would seem, of minute sand, penetrated 

 with siliceous liquor or pure quartz. 



3. Little dark grey nodules, in a lighter ce- 

 ment, of a yellowish white. 



4. A fawn-colour cement, in some places in- 

 clining to white, in others tinged with red, and 

 studded with chalite of bluish grey, pale brown, 

 lead colour, all inclosed in black zones, with 

 one large nodule of a fine light lilac spotted with 

 white, surrounded by a broad zone of yellow, 

 which is followed as usual by an outline of black. 



5. A slab, polished on both sides, of six inches 

 square, containing great varieties of brown and 

 yellow chalite, often with zones or tinges of 

 lilac, purple, and a faint olive green. Many 

 are spotted, with various tints, while others have 

 numerous zones, like agate. The whole in a 

 cement of coarse sand, of the same nature, agglu- 

 tinated by transparent quartz, so that the sub- 

 stances appear as if seen through glass. A large 

 pebble, of three inches by two, presents a sin- 

 gular accident; a large portion of the cement 

 appearing in its centre, in such a manner as to 

 leave rio doubt that both were liquid at the same 

 time, or must have crystallised together. The 

 white pebbles have more the waxy appearance 

 of chalcedony than of flint.
