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 earliest 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 ‘ diurnaf 
geological causes. 
The Zoological collections have been greatly augmented 
especially in the Ornithogical department ;—the untiring 
liberality of Mr. Allis, 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
