extraordinarly abundant in fish-remains of upwards of thirty species. The 

 fossil fishes are of a black colour, and some iii a very high state of preservation, 

 but usually they are extremely fragmentary. The fossils are not found hi 

 nodules there, but are seen on the flags, or slabs, as they are removed from the 

 quarries. The stone is almost black, or sometimes brownish, and contains a 

 large amount of bituminous matter. In some places it is quarried for the 

 manufacture of the paraffine-oil, which is obtained by simple distillation from 

 the sandstone slabs. This great amount of bitumen seems to be owing to the 

 vast quantity of organic matter contained in this sandstone. Many of the slabs 

 have an oHy appearance and a strong bituminous odoui\ 



In the neighbourhood of Thukso are several quarries, where many fishes 

 may be found, as also near STiio:y[XESs, in Pomona. In some of the sandstone 

 slabs are found small nodules ; these are formed by a nucleus of iron-pyrites. 



In the neighbour-hood of Edinburgh, at Bathgate, large quantities of 

 paraflfine-oil is manufactured from the refuse bituminous minerals and rubbish 

 from the coal-pits of the neighboui'hood. — James E,. Gregory.
