P.S. — Mr. Bristow, F.E.S., informs me that he has seen no reason 

 to form any other opinion than the ordinarily accepted one, of a fault 

 in this railway cutting, on the occasion of visits paid to it in 1867 

 and 1868. 



IGNEOUS EOCKS OF CARBONIFEROUS AGE IN IRELAND. 

 Sib, — In the article " On the Basaltic Eocks of the Midland Coal- 

 fields," by Mr. Samuel Allport, F.G.S., which appeared in your last 

 number (p. 159), the author refers to the Scottish igneous rocks of 

 Carboniferous age, but quite ignores those of the same period in 

 Ireland, although descriptions of the latter were published long 

 before those of Scotland. G. H. Kinahan. 



FOSSIL INSECTS IN THE BOURNEMOUTH LEAF-BED. 

 Sir, — The Eev. P. B. Brodie, iu the March number of the Geolo- 

 gical Magazine, p. 141, directs the attention of the explorers of 

 the Leaf- beds in the Lower Bagshot Series of Hants and Dorset, to 

 the desirability of looking out for Insect-remains ; particularly at 

 Bournemouth. Mr. Brodie may be glad to learn that Mr. Wanklyn 

 has already recorded the discovery of Insect-remains at Bourne- 

 mouth, in the Annals and Mag. Nat. Hist, for January, 1869, 4th 

 series, vol. iii. No. 13, p. 10. The specimen has been placed by 

 the discoverer in the hands of Mr, W. S. Dallas, F.L.S., the 

 Assistant Secretary of the Geological Society of London, who has 

 kindly undertaken to examine and describe it. — J. P. Walker.

The Gigantic Oolitic Lizard (Cetiosaurus). — "We called attention to 

 the discovery of the thigh-bone of this great Lizard (GEOLOGICAL 

 Magazine for July, 1869, p. 336, Vol. VI.) in a quarry at Enslow 

 Bridge, near Oxford. Prof. PhilHps now announces ^ the discovery of 

 further remains of Cetiosaurus. " The space of ground in which the 

 bones are found (writes Prof. PhiUips) is apparently quite limited. 

 One may think the whole body of the vast old Hzard, in the extremity 

 of age, was here laid to uneasy rest ; the parts separated by decay ; the 

 massive limbs disjointed, and the bones displaced. Imagine a surface of 

 the ossiferous clay which covers the Oolite laid bare by the workmen. 

 Look southward : before you are four bones laid rudely parallel, in a 

 row, at intervals of 1, 2, or 3 feet. They are 64, 54, 45, and 37 inches 

 long ; 10 inches the least breadth in the narrowest part ; 26 inches the 

 greatest breadth in the widest part. These are bones of Cetiosaurus. 

 Over them and in front of them, three days since, lay as many others, as 

 large and as quietly reposing in their " longseval " graves; behind 

 them, possibly, are still more bones, to be discovered at some future 

 time. Bones of a much mightier area — probably hugest of all huge 

 iHa — extended far and wide; vertebrae 8, 9, and 11 inches in diameter; 

 monstrous ribs, of which the parts traceable and inferred are 59 inches 

 long ; all this within the compass of a few square yards. It seems like 

 the burial-place of the great father of lizards, each of whose bones 

 demanded — but only some could obtain — a separate grave."
