the position of the lower Rothliegendes of Dr. Geinitz 

 and the German geologists. 



The Astley beds very much resemble similar pebbly grit- 

 stones seen in the upper part of the Pottery coal-fields of 

 North Staffordshire^ and have some resemblance to the 

 Hooton-Roberts and Went-Bridge rocks of Yorkshire, as 

 well as to those at Moira near Ashby-de-la-Zouch, before 

 alluded to. 



The Newtown and Bedford limestones to me appear, both 

 by their physical and chemical characters, position, and 

 organic remains, to resemble the thin-bedded limestones 

 of Hooton Roberts, Hampole, Bolsover, and Kirkby Wood- 

 house, more than any other permian beds which have come 

 under my notice. This opinion is different from that of 

 my friend Professor King, of Galway, and other geologists, 

 who regard these Lancashire limestones as the representa- 

 tives of the higher magnesian limestones of Nottingham- 

 shire, Derbyshire, Yorkshire, and Durham; but it is in 

 accordance with the views of Mr. Kirkby, who has examined 

 the organic remains of this part of the permian series 

 with great care and ability.

I HAVE for a long time endeavoured to obtain some sub- 

 stantial results relating to the products of decomposition 

 of substances in a putrid state. I have not, however, until 

 lately proceeded in a direction such as to satisfy myself, 

 and even now am only at the commencement of the sub- 

 ject.
