DU NOYER — NOTES ON THE OIANt'S CAUSEWAY.

ously tlic palo " queen of night" must have shed her rays along that 
gUstening ti-act, and how fiih- and white the long curling shore-waves 
must have looked, as they caught with their rolling crests her silvery- 
beams, and perchance reddened in the glare of some raging volcano. 
Over the endless ocean the glittering flood of light ranged away, until 
far, far off in the grey and misty horizon, it mounted to the clouds, 
and seemed to mingle earth with heaven. How beautiful must have 
been the moon's light then, when only the trilobites turned their 
hundred-lensed eyes towards her, and skipping Hymenocarides ia 
their sportive progress, spattered out of the shadowy pools sparks 
and flashes of bright light. What a world of silence, unbroken save 
by the rushing of the wind, or the murmurs of the sea. No beast 
upon that oosy land, where nor grass nor herbage grew. No birds 
nor insects in that dewy air ; nor waves nor ripples landed the glit- 
tering fish upon those slimy shores ; the wide expanse of waters was 
untenanted by the scaly tribe, and the sluggish shell-fish, worms, and 
three-lobed crabs, and their slirimp-like congeners, were the sole 
tenants of the earth.

NOTES ON THE STRATIGRAPHICAL POSITION OF THE 
GIANT'S CAUSEWAY, AND THE STRUCTURE OF THE 
BASALTIC CLIFFS IMMEDIATELY ADJOINING IT. 
By Geo. V. Du Noyer, M.R.I. A., Senior Geologist of the Geolo- 
gical Survey of Ireland. 
During a visit to the Giant's Causeway in the month of September, 
1857, I made a few notes and sketches on the spot, having reference 
more particularly to the determinating of the stratigi-aphical position 
of the Causeway itself, and to get if possible a clear idea of the struc- 
ture of the exposed clifi'-sections of the basalts in the immediate 
neighbourhood. On comparing my observations with an account of 
the causewaj^ and the adjoining coast given by the Rev. John 
Dubourdien in his statistical survey of the county of Antrim in 1812, 
I was struck with the discrepancies which exist between them, the
