RoBEKTSON, D., and Ckosskey, Rev. H. W. On the Post-Tertiary 

 Fossiliferous Beds of Scotland. Trans. Geol. Soc. Glasgow, vol. iv. 

 part iii. pp. 241-256. 1 plate (plan), 2 woodcuts. 

 This is the continuation of a paper ending at p. 137 of the same 

 volume. The localities described, whence fossils have also been col- 

 lected, are the Jordanhill Brick-works, Stobcross, Fairfield near Govan, 

 Paisley Canal, and Dipple Tile-works. Full lists of fossils are given 

 (no new species), and also details of borings through the Drift. G. A. L.

vol. xi. pp. 458, 491 (1873). 

 The rocks are as follows : — Middle Coal Measures, 850 feet ; Lower 

 Coal Measures, 1226 feet; Upper Grit, or Rough Rock, with flags at 

 base, 180 feet ; Shales, 110 feet ; Middle Grit, in several beds, 1400 feet. 

 Each division is described, and the various economic products are men- 

 tioned. The lie of the rocks and the scenery which they produce are 

 then described ; and the paper concludes with an account of the boulder- 

 beds and river-deposits. W. T.

The divisions of the Lias, in all 850 feet thick, are the oldest beds ; 

 and then come the Northampton Sands, 80 feet thick, the lower part 

 of which is now largely worked for iron-ore, and the upper part is of 

 estuarine origin. These sands are succeeded by other members of the 

 Inferior Oolite, known as CoUyweston Slate and Lincolnshire Lime- 

 stone, the latter of which yields some good building-stone. Then come 

 some clayey beds of estuarine origin, classed with the Great Oolite, and 

 succeeded by the limestone of that formation ; then a representative 

 of the Bradford Clay, Forest Marble, Cornbrash, and Oxford Clay. The 

 high lands have often a capping of Boulder Clay and Gravel, whilst 

 the valley-gravels (of later date) yield remains of elephant, rhinoceros, 

 hippopotamus, &c., and are sometimes succeeded by a peaty fluviatile 

 deposit with bones of ox, deer, horse, &c. The range of the various 

 beds is noticed, as well as the physical geography of the county ; and 

 it is inferred that no Coal Measures occur at a workable depth. W. W.
