254 
organisms he had found in the Charterhouse lead mine, 270 feet 
deep, and in other vein stuffs sent him for examination from 
various parts of England, alluding particularly to the curious 
organisms before mentioned, i.c., the Conodonts. Appended to 
the report are some notes by H. B. Brady, F.L.S., on the Fora- 
minifera of Mineral veins and the adjacent strata, sent him by 
Charles Moore for examination, a large proportion representing 
forms not previously described. 
At the Brighton Meeting in 1872, we were associated together 
as Co-delegates to represent our Field Club, at the Conference held 
under the Presidency of Dr. Carpenter respecting the organiza- 
tion of Local Scientific Societies ; and Moore gave an account of 
some naked Echinodermata (Holothuria) from the Jurassic beds. 
One species of these, allied to Chirodota, has its skin furnished 
with minute wheels, and though of course the soft bodies of these 
animals have disappeared in a fossil state, yet he had discovered 
the wheel-like plates of at least four species of Holothuria in the 
Lias and Oolite ; one from the Inferior Oolite, one from the Upper 
and two from the Middle Lias. These plates were about = of an 
4 
inch in diameter and presented considerable variety in form. 
One of the prettiest forms from the Inferior Oolite he named after 
the President of the Association, Dr. W. B. Carpenter, Chirodota 
Carpenteri. He concluded with the expression of a hope that 
this interesting class of animals would receive a more systematic 
study than had hitherto been given them. 
At the Bristol Meeting in 1875, he discussed the age of the 
Durdham Down Conglomerates yielding Thecodontosaurus and 
Paleosaurus, and considered by Messrs. Riley and Stutchbury, 
about 40 years’ before, as of Permian age, but since then referred 
to the Magnesian Limestone. He gives his reasons for believing 
them to be still more recent. In his opinion precisely similar 
physical mineralogical and paleontological conditions prevailed 
on the table land of Durdham Down as in the Mendip area. 
Numerous veins traversed the Carboniferous Limestone ; from
