1850.] BRODIE ON THE INFERIOR OOLITE. 247 



friend Professor Buckman has also reyised the list, and his previous 

 acquaintance with the formation under review gives additional con- 

 firmation to these details. 



My friend Mr. Gomonde, of Cheltenham, however, was the first to 

 investigate the organic remains of the freestone at any length, and to 

 point out the number of species, which his fine local collection amply 

 illustrates. He has also added some new species from other beds, 

 especially the rubbly oolite (No. 3 of the Section, p. 242), and Piso- 

 lite, which had not been previously brought to light in Gloucester- 

 shire. Indeed, I have to thank him for much information and assist- 

 ance in my examination of this member of the lower oolite. 



The freestone is succeeded by the Pisolite (" Pea-grit"' of Mur- 

 chison), and ferruginous oolite {Belemnite bed) and sand (No. 7 of 

 Section) ; the former so called from its peculiar structure, being 

 composed of large oval grains, of a yellow colour, cemented by cal- 

 careous matter, the whole not exceeding forty- two feet thick. It con- 

 tains several shells and minute corals. At Crickley and Cleeve the 

 Pisolite is much thicker than at Leckhampton, and the ferruginous 

 oolite may be occasionally observed beneath. This latter rests con- 

 formably on the clays of the upper lias, which it is not within the 

 province of this paper to describe.
