county of Cork. In this section the vertical scale is to the 
horizontal scale as twelve to one ; which necessarily produces 
great distortions in the relative position of the mineral masses*. 
Let us first consider that portion of the section which lies 
between the valley of the Suire and the vale of Dungarvan, 
the latter of which extends w'estward to the Blackwater. 
With respect to the relative position of the carboniferous 
limestone of the valley of the Suire as reposing on old red 
sandstone, both on its northern and southern sides, there is no 
question. South of the river, the old red sandstone, which 
there forms a narrow border, reposes unconformably on the 
clayslate formation, the former dipping north and the latter 
south. These relations may be observed in many places, 
and are well exemplified in passing from the river Suire up 
the defile which leads to the Glenpatrick slate quarries, about 
three miles to the east of Clonmel!, and which unconformable 
position is admitted by Mr. Griffith himself f. The same 
relative position is to be observed upon the range eastward ^ 
also, and to the south of Carrick, through which Mr. Griffith’s 
section passes ; but Mr. Griffith there makes the clayslate 
of the hill of Carrick, as well as the clayslate extending to- 
wards the Monavoullagh range, to dip north, though just 
contrary to the fact, the dip being south ; and by interposing 
a bed of conglomerate, all north of this, extending to the 
limestone of the valley, is called an ‘^old red sandstone series,” 
than which assuredly nothing can be more incorrect. For 
the details I have given, as well as general views affecting this 
region, I must refer to the 144th section of my Memoir on the 
east of Ireland^. I have already remarked that the older 
stratified rocks on which the Monavoullagh range rests, dip 
generally south, yet are subject to local inflections to the 
north ; but Mr. Griffith in his section represents the whole 
of these older rocks as vertical in the centre, from which 
the strata are made to incline on the southern side to the 
south, and on the northern side to the north, the latter being, 
as I have already stated, contrary to the fact. I have also 
same objection, but they are at variance with themselves, the author re- 
presenting what he terms “old red sandstone” to dip in fig. 1 generally 
south, and in fig. 2 generally north. They are also at variance with his 
former sections, given in the Journal above referred to, but especially so 
with the matters of fact. An unrestrained indulgence of fancy, with a 
loose application of the terms Cambrian^ Silurian, old red sandstouQ, &c., can 
tend little to the advancement of Geology. 
* The deceptive effect of such sections has been ably shown by Mr. De 
la Beche in his Sections and Views illustrative of Geological Phaenomena.
