which that of Sir Philip Egerton is alone comparable. A list of 

 the genera and species drawn up hy his Lordship has already 

 appeared in the Geol. Mag.^ In this district he had an ex- 

 cellent opportunity of examining the succession of the Lower 

 Carboniferous rocks, from their base along the shores of Lough Erne, 

 where they repose on the Old Red Sandstone, up to the Millstone- 

 grit ridge of Cuilcagh, which rises 2,187 feet above the sea. The 

 limestone in this district is rich in coralline^ and crinoidal remains ; 

 Pentatrematites Derhienais, Platycrinua, etc., and the author records 

 the occurrence of Amphoracriuus Gilhertsoni, in the cliffs of the 

 upper limestone which rise boldl}'^ above Florence Court Park. 

 Need we say, that with Lord Enniskillen and his family our author 

 is fairly captivated, and that he bids farewell to the hospitable 

 " Schloss," with feelings to which he gives expression in the follow- 

 ing passage : " Als wir uns in der Halle der irischen Riesenhirsche 

 herzlich von unsern gastlichen Wirthen verabschiedeten, trugen wir 

 eine unausloschliche, freundliche Erinnerung an das griine Florence- 

 court und seine edlen Bewohner vou dannen. Mogen sie, wenn 

 dieses Blatt ihnen zu Gesichte kommt, es als ein Zeichen unserer 

 Yerehrung ansehen und der deutschen Giiste aus dem fernen Osten 

 wohlwollend gedenken " (p. 135). 



From Enniskillen the author and his companion proceed to the 

 north-east, travelling along the valley of the noble river Foyle to 

 Londonderry, and thence proceeding to the Antrim coast, with the 

 scenery and geology of which he is greatly delighted. Visiting the 

 town of Antrim on his way southwards, he examines the celebrated 

 " Round Tower " of that place, of which a picture is given (p. 161), 

 as well as the tracliytic district of Tardree Hill ; and here the author 

 justifies his high reputation as a mineralogist, by the discovery of 

 that rare form of silica, called " tridymite " by Vom Rath, which 

 appears to be abundant in the drusy cavities of the trachytic lava. 

 Further on his way, he visits the celebrated plant-bearing beds of 

 Bally palidy of Miocene age ; and after a short stay in Belfast, 

 finally takes his departure lor Scotland, to be present at the meeting 

 of the British Association.

WE have often wondered why our Geological Literature con- 

 tained no general key to the structure and features of Ireland. 

 That the ' Green Isle ' could boast of more than one ' son of the 

 hammer ' who was competent to lay such a summary before his 

 brother geologists, we knew, not only from the enjoyment of 

 personal intercourse, but from an acquaintance with their published 

 labours. Yet we had it not. More than five years since, the
