440 HIND : CARBONIFEROUS ROCKS OF THE PENNINE SYSTEM. 
Shale, 2 feet. 
Thin Limestone, 1 foot 6 inches. 
Shale, 4 feet.

Sandy Shales, 6 feet. 
Shales, 6 feet. 
Limestone, 75 feet. 
In his Furness paper (Op. supra cit.. Vol. XXXL, page 215), 
Mr. Kendall estimates, from borings and sections, the thickness of 
the limestone in the Furness district as 946 feet, and this mass contains 
only about 34 feet of interbedded detrital rocks. 
Above the mass of the limestone of Furness shales with limestones 
are to be found, and it will be a matter of importance to ascertain 
whether they contain the Pendleside fauna or not. Personally I have 
only examined the shales in the stream section north of Borwick Hall. 
A series of sandy and muddy shales with sandstones were seen, but 
the only fossils obtained were fragments of plant remains and scales 
of Megalidhys Hibberti. 
Unfortunately no paleontological evidence is mentioned in Mr. 
Kendall's paper, but the important fact remains that during the 
deposition of the limestone, currents bearing detrital mud and sand 
did not reach Furness to any extent, but they did reach the district 
of West Cumberland, and caused the division of the limestone into 
distinct beds. 
The plates of Mr. Kendall's paper, Vol. XXXIV., Plates XIIL 
and XIV., of supra cit., are very instructive, the gradual change 
of the series being shown by parallel columns of actual sections, and 
finally compared with the section of the Carboniferous series at Wear- 
dale and Allen Head. The change of the Yoredale phase into that of 
the southern type of Carboniferous rocks is, in the West Cumberland 
and Furness districts, therefore demonstrated to be very gradual, and 
a comparison of figures representing the proportion of shale to lime- 
stone in the Furness, Egremont, and Alston Moor districts is very 
instructive. 
The numerators represent the thickness of shale, the denominators 
the thickness of limestone : —
