or cows. When from heat they are troubled with what 

 he termed red or bloody water, he beats the gryphaea to 

 a fine powder, with which, mixed with whey, he 

 drenches the animal, and the complaint is immedi- 

 ately cured.] 



Large blocks, composed of fragments of shells, mixed up 

 together by a calcareous cement, containing specimens of 

 Pecten, spines of Echinus ^ Ostrea Edulis, Serpula Buccinumy 

 Mya, and Pentacrinite. These blocks are found at the bottom 

 of the gravel, immediately reposing on the lias, and some of 

 ihem have been known to weigh from 80 lbs. to 1 cwt.

Fragments of the horn of a stag, Elephas Cervus of Cuvier, 

 ten feet below the surface of the bank of the river, at the 

 bottom of the gravel, imperfectly mineralized. 



Jaw of Deer.

Fragments of Os Frontis of Ox.

Horn of do. 



Metacarpus of do. 



Astragalus of do.

The organic remains of the blue lias are, 



Ammonites gigantea. 

 I have found a specimen of this species measuring two feet 

 eight inches in diameter*. 



• In the New Monthly Magazine for July, 1827, p. 316, we read the following 

 notice : — " As some labourers were lately taking down the vicarage-house at Awre, 

 in this county (Gloucester), they discovered several extraneous fossils imbedded in 

 claystone. It is very probable they came from Church Rock, in the river Severn, 

 which is not far distant. The house, it appears, has been standing four or five 

 centuries, and the stones exactly correspond with those now seen in the remains of 

 the abovementioned rock, which is impregnated with numerous fossil shells of 

 various species. A large Cornu Ammonis, more than three feet in diameter, and 

 a beautiful specimen of the Plagiostoma Gigantea, are removed from the old vicar- 

 age walls into the collection of Mr. R. Ryder." This gentleman (Mr. Ryder) has 

 resided in the parish of Awre for upwards of twenty-six years, at but a short dis- 

 tance fromt the "Severn. During that period he has constantly visited the shore, 

 and has made a most valuable collection of its fossils. Specimens (I believe) of 

 all the organic remains enumerated in this memoir are in his possession ; and I 

 know that he feels peculiar pleasure in shewing his collection to any one who, like 

 himselfj takes a lively interest in geological inquiry.
