The discovery, by Professor Harkness, in the central member of this 
siliceous group in Westmoreland, of numerous fossi plants identical 
with the species of the Kupferschiefer in Germany, and in the Marl- 
slate of the Magnesian Limestone of Durham, was given as a strong 
proof of the correctness of the authors’ conclusion 
The ep eo scarcity of igneous rocks, and the evidence of ners 
ful chemical action, in the Permian strata of uct is contrasted w 
their eaulenne in deposits of that age in Ger ; but proofs are 
nevertheless brought forward to show that the hentai of Cumberland 
and Lancashire was formed in the early accumulation of the Permian 
deposits. 
In describing i in detail the different members of the Permian group of 
the northwest of En land, the authors define the ae and upward 
tain bands of salearonss breccia (the “ brockrum > of the praetic whic 
oceur in the central portion of the series, contain much magnesia, the 
lower breccias, 00 of the same mountain-limestone fragments, ie 
no trace of it; nor is it to be detected in the upper member, or St. Bee 
Sandstone.—Phil. Mag., [4], xxvii, 542.

raced in a line - section from the Nigg to Cambus Shandwick, from 
above the gneiss to the foot-print sandstones of Tarbet-ness inclusive, are

of the d Red Sandstone— e—namely, the conglomerates and yellow genie

thodes, and thus referable to the Middle Old Red; thirdly, conformable
