Z BEPORT OF 



from the Wealden formation ^ ; some of the most curious 

 of the later discoveries in the Lias of Dorsetshire have been 

 furnished by two of our earhest friends 2 ; many contribu- 

 tions have been received from the Yorkshire coast, through 

 the personal exertions of three Officers of the Institution ^ ; 

 and the general history of these remarkable deposits has 

 been aided by a contribution of fossils from the analogous 

 strata of Brora ^. With deep and grateful satisfaction has 

 the Geological Museum been consulted by many eminent 

 men of science ; — and it has recently furnished to M. Agassiz 

 materials which he thinks of great importance for the comple- 

 tion of his magnificent volumes on Fossil Ichthyology. 



The MiNERALOGicAL Cabinet has received only two ad- 

 ditions, but these are of peculiar value ; the series of stalacti- 

 cal and other forms of perfectly crystallized carbonate of 

 lime, from the Kingston cave, near Cahir, ^ and the fine 

 crystals of sulphate of lime formed in the abandoned 

 galleries of Felling Colliery, teach important truths as to 

 the power and action of what have been called *diurnar 

 geological causes. 



The Zoological collections have been greatly augmented 

 especially in the Ornithogical department ; — the untiring 

 liberality of Mr. AUis, and Mr. Healey, well seconded by 

 the contribution of several remarkable specimens, and by 

 a purchase effected on most favourable terms, has supplied 

 many of the most obvious deficiencies in this department 

 of science. 



The new Zoological ' Museum will, therefore, immediately 

 receive one thousand specimens of Birds, and a considerable
