stands, and the crotesqiie caves of Ciishendun, are found in 

 this material," Dr. D. pref. xiii. and p. 143 : this pudding- 

 stone is notictd particiilarlv bv Mr. D. at page 92 and 94. 

 I am inclined however to think it a coarse and very irre- 

 gidar gritstone, as to the size of the grains, of which I 

 have seen many examples in Red Marl districts. 



MugnesianLumestone,\h\% appears on the S shore of Bel- 

 fast Lough, at Hollywood in Downshire, and by Dr. D. 

 pref. vi. is supposed to underlie the Sandstone : many miles 

 N of this at Tor Point there is " a dark -blue primary or 

 transition Limestone with veins of chlorite and calcareous 

 spar," Dr. D. pref. xiv. 



Gneiss, Mica Slate, and Granite appear in Cushleak, the 

 shores here being bold but not perpendicular, Dr. D. pref. 

 xiii. ; and Grey-wache and Schist, and Granite are said, 

 probably, to underlie the magnesian Limestone of Holly- 

 wood, pref. vi. 



" Porphry in unconfarmable strala of a yellowish and 

 bluish external surface, containing veins oi' Jasper," occur 

 in Cushendall Bay, Dr. D. pref. xiii. What Dr. R. and 

 Mr. D. have said of the Slate, Gneiss, and Granite, in-land, 

 at the NE corner of the County, have been noticed already 

 at page 2G9, and it remains 1 think only to mention, that 

 a vein of Lead appears in Magee Island, Dr. D. pref. xii. ; 

 that Manganese is found near Bailycastle, S (f suppose \i\ 

 these strata?) Mr, D. p. 62, and Slieve Aura mountain 

 " has been long supposed to contain Mines," or veins 

 rather. Dr. D. App. p. 33. 



Such are the varied substances which the south-eastern, 

 east, and north-eastern borders of Antrim I'urnish, from 

 what 1 consider as different parts of the same thick stra- 

 tum, without being furnished with the means of tracing 

 any invariable law as to their disposition, or thinking that 

 such can be there traced (if such exists) any more than in 

 another stratum of similar properties which 1 have else- 

 where examined, and which nothintj; but the succession of 

 well marked and diflercnt strata (the Lias, &cc.) almve it, 

 could hinder us from concluding to be the very same 

 stratum. 



Second — A great Limestone stratum, or rather an assem- 

 blage of calcareous strata, whose parallel [ilancs are applied on 

 the Marl (or its anomalous bed.>), and e.^cept at the north-' 

 east and south-east corners of Autrmi county, but little of 

 the JMari rcnia.ns uncovered thereby, while the surface 

 which the Marl or its imbedded substances make, in the 

 mountains of Down, Louth, Armagh, Monaghan, Tyrone,
