which are thin, as in Ballynascreen, the fossils are only those found at Clifton. 

 Then, again, in the largely developed Glengarifl" beds are found fossils identical 

 with those of the Marwood sandstone. 



This is ifiore easily seen by the following Table : — 



The author then asked, ought these shales to be classed with the Carboniferous 

 or Devonian rocks ? He submitted that the evidence produced clearly proved that 

 they were the former. 



1st. On account of the nature of the fossils. 



2ndly. From the comparatively large extent of limestones and marls (70 feet) 

 before the true micaceous beds begin, and 100 feet above the first bed of quartzose 

 conglomerate. Another view was laid before the Association, viz., that these shales 

 probably had as much right to be considered a distinct and intermediate series as 

 the Eheetic of the Lias, which in the Rhsetian Alps have little more thickness than 

 the Lower Limestone shales, which in Glengariff Harbour range through more than 

 5000 feet.

On a Bone Breccia ivith Flints in Lehaiwn. 

 By the Eev. H. B. Tristkam, M.A., F.L.S. 

 Close to the Nahr el Kelb, on its southern side, a spur of the Lebanon pushes 

 boldly into the sea, standing out a promontory severnl hundred feet high. Above 

 this the rock has been scarped for the inscription of those famous tablets which are 

 known to every visitor to Beirut. The hard ci-ystalline limestone was in one spot 

 under this a complete mass of bone breccia, with fragments of flint mingled in the 

 stalagmite. It seems probable that the stnlagmite, of which not above twelve 

 square yards remain, formed a portion of the flooring of an ancient cavern, the 

 roof of which has probably been cut away, either to aid in the consti-uction of the 

 road, or to obtain a surface for the inscription of the tablets. The position of the 

 breccia being several feet above the level of the roadway, the floor of the cave, no 

 doubt, originally extended as far as the sea-face of the road. We therefore descended 

 to the sea ; and, amongst the heaps of rock, dashed by the waves and covered with 

 fucus, we discovered several large frnsments of breccia, con-esponding exactly in 

 composition with the mass above. The flints consisted almost entirely of elon- 

 gated chips with very sharp edges ; and the author reniiirked that he was not aware 

 of any natural deposit of eilex within three miles of this spot. Many of these chips
