diluvium. Of this part of the collection there is only one drawer, 

 containing no specimens of any interest. It may, therefore, be con- 

 sidered as very deficient. 



Diluvium. All superficial transported materials not connected 

 with the existing drainage of the country, are arranged in this divi- 

 sion. The vertebrated animals, as in all other parts of the series, 

 have been classed according to the system of Cuvier, and the inver- 

 tebrated according to that of Lamarck ; and many of the specimens 

 have been specifically determined by the Curator. 



Cavern Remains. There is a good series from Kent's-hole ; but the 

 collection from Kirkdale is defective ; and from Banwell and other 

 localities there is not a single specimen. 



Bovey Coal. This deposit is badly illustrated. 



Crag. Of the organic remains there are many fine specimens; 

 but the collection is defective in the rock itself, and several species 

 of corals and shells are wanting. 



Fresh Water Formations. These are tolerably complete; and the 

 inferior tertiary formations are equally well illustrated. 



Chalk. A good series, but many species of the organic remains 

 are wanting. 



Green Sand Series. It is comparatively perfect ; but it requires 

 many additional fossils, particularly from the lower green sand. 



Weald and Hastings Formations. Of these deposits there are some 

 good specimens ; but on the whole the suite is incomplete. 



Purbeck and Portland Beds. There is a want of organic remains, 

 especially of the silicified woods and vegetables. 



Kimmeridge Clay. Specimens of the coal and even of the charac- 

 teristic fossils are very deficient. 



Coral Rag Series. The calcareous grit of this division is poor in 

 organic remains. 



Oxford Clay. There are only a few imperfect specimens of rocks 

 and fossils ; this portion of the oolitic series being worse illustrated 

 than any other in the Museum. 



Lower Oolitic System. Of the succeeding members of the oolitic 

 series and the lias, the most deficient in fossils are the great and in- 

 ferior oolites : in other respects this series is rich. 



We must here, however, remark, that there is yet an almost entire 

 want of the plants and fossils of the oolite coal-field of Yorkshire. 



New Red Sandstone and Magnesian Limestone. There is a fine 

 collection of rock specimens ; but the rarer organic remains, such as 

 the fishes of the marl-slate, are wanting. 



Coal Measures. The suite from the north of England is rich, 

 whilst that from the south-western coal-field is singularly poor. The 

 former owes a considerable portion of its value to the recent dona- 

 tions of fossil plants by Mr. Hutton. 



Mountain Limestone. The rock specimens are numerous, but the 

 organic remains are few in number. 



The Curator has not advanced further with his arrangement of the 

 inferior formations, and therefore the Committee cannot report upon 

 the value of the suites of transition and prima! rocks, of which there 

 is, however, a very large number.
