214 Geologi/, <|-c. of Malbay^ L. C. 



in sets of (en or fifteen. It is compact, minutely granular, 

 and rather hard. Its fracture is slaty in the large, rhom- 

 boidal in the small. It gives a sulphureous odour on per- 

 cussion, and here and there contains a few shells. Its lay- 

 ers sometimes gradually dilate, or belly out, in portions, 

 and contain some form of the general conglomerate of the 

 cliff". It even occasionally takes the fine crystalline texture 

 of the Limestone of Montmorenci or Point aux Trembles: 

 but this is rare. 



A brown or black splintery slate is often interposed be- 

 tween the conglomerate and the dark Limestone ; and is 

 plentiful at the Cave. 



1 had no opportunity of examining the higher parts of the 

 West Hill skirting the Bay : by far the greater portion of it 

 is buried, as before stated, in irregular terraces of alluvion. 

 The breach, however, below, exhibits intervals of the less 

 durable calcareous rocks of the west angle, and not of 

 the primary strata of the Hill, as might have been ex- 

 pected. 



At each end of this arm of the Bay, small quantities of 

 the conglomerate are met with ; — not to be distinguished by 

 the eye, from Grey wacke, on account of the faint green 

 colour of its base. — Near the outer precipice, it is much 

 interleaved with the dark limestone ; and contains a (evf 

 shells. 



In a grassy meadow, near the church, a more compact 

 form of the conglomerate emerges from the soil in slabs in- 

 clining to the south-south-west at an angle of 25°, a dip 

 which I believe to be accidental from (he extreme disorder 

 of some contiguous strata of dark Limestone. There is 

 another portion at the foot of the Middle Hill, near some 

 low mounds of porphyritic grey gnei:?s. 



Several patches of the dark Limestone occur on the 

 beach, two of them being four or five hundred yards in 

 length. 



Like the Mica-slate of the Hill, it dips to the north- 

 north-west at an high angle, excepting the large mass allu- 

 ded to above, which inclines, in groupes of strata, in every 

 possible direction. 



I did not observe any organic remains in the Limestone 

 here, nor other accidental mineral, excepting white calc 

 spar, which often traverses the rock so plentifully in 

 slender veins, as to give it a brecciated appearance.
