the former of which is now in progress. The system 
adopted, with occasional slight deviation, is that of Pro¬ 
fessor Berzelius, founded upon the electro-chemical 
theory and the doctrine of definite proportions. In its 
present unfinished state, the detail of the arrangement 
cannot here be entered into ; it is, however, partly sup¬ 
plied by the running titles at the outsides of the glass 
cases, and will be further illustrated by the labels within 
tricht, presented, in 1784, by the celebrated Peter Camper, and 
figured by Cuvier;—a portion of a new species, frpm Lyme Regis, of 
the remarkable genus of fiying reptiles, the Pterodactylus of Cu¬ 
vier, described and figured by Buckland in the Transactions of the 
Geological Society, under the name of P. macronyx; together with a 
coloured cast of the unique P. longirostris of Cuvier from Solenhofen, 
the quarries of which place have also furnished the small lamina of 
lias on which may be observed the impression, with some of the os¬ 
seous substance remaining, of the two last articulations of the toe of a 
flying animal, considered by Spix as related to the Vampire, but 
which is more probably a large and distinct species of pterodactyle.— 
Among the specimens of the genera Ichthyosaurus and Plesio¬ 
saurus, which form a distinct order in the class of Reptiles, are r— 
a very perfect head (formerly in the museum of Mr. Bullock) of a 
pretty large specimen of the common ichthyosaure; part of the head 
of another of still larger dimensions, cut transversely to show r the 
internal structure of the jaws; the humerus and carpal bones of a 
most gigantic species (I. immanis ): all from the lias of Lyme Regis; 
anew small species (Ichtil. latifrons ), in which the spiracle on the 
top of the head, between the eyes, claims particular attention; this 
specimen was found at Baldertonin the county of Nottingham, twelve 
feet under the surface, about three miles and a half south of Newark- 
upon-Trent, near the drain dividing the counties of Lincoln and Not¬ 
tingham, in afield adjoining the great north road, and was presented 
by Dr. Bland.—From nearly the same locality is the specimen here 
deposited of a species of plesiosaure, an account and figure of which 
have been given in the Philos. Trans, for 1719, by Mr. Stukely, who 
took it for a crocodile;—a very perfect specimen, with head exhibiting 
the teeth, of the long necked plesiosaure (Plesiosaurus dolichodeirus 
of Conybeare) from Lyme Regis; and a coloured cast from an ap¬ 
parently specifically distinct specimen, in the possession of Mr. T. 
Hawkins, found at Street in Somersetshire.'—As illustrative of the 
natural order of Chelonidae, we have some interesting specimens, 
chiefly from the isle of Sheppy.—The only fossil species of the Batra- 
chian reptiles in the collection is the gigantic Salamander, the subject 
of worthy Scheuchzer’s dissertation, Homo diluvii testis et theoscopos .
