obstacle to the current of water from the higher land. In 1818 
one of the lakes, Loubando, which discharged its waters eastward 
into the Voxa, opened a passage into Lake Ladoga eastward, 
by bursting through the isthmus of Taipala, a circumstance that 
will probably alter its future geographical character. 
A paper was also read, from Dr. Adam, of Calcutta, “ On 
the Geology of the Banks of the Ganges from Calcutta to 
Caunpore.” 
There is no rock on the banks of the Hoogly or Ganges 
between Calcutta and the province of Bahar. The soil consists 
of a mixture of argillaceous earth, sand, and minute grains of 
mica, and is highly favourable to vegetation. 
After leaving the low lands of Bengal, the Ragemaal chain 
of hills present themselves ; of these, as well as other hills 
between this chain and Monghyr, the author has sent a series of 
specimens as a necessary illustration of his paper. 
After leaving Monghyr, the country again becomes flat, and 
continues so for upwards of 200 miles; at Chenor, there are 
several low ranges of hills ; between these and Caunpore, there 
is neither rock nor rolled stone; but the soil consists chiefly of 
clay, sometimes considerably indurated. 
March 5.—An extract was read of a letter from Whitby, from 
the Rev. George Young, addressed to Samuel Parkes, Esq. 
contaming an account of the discovery near Whitby of the fossil 
remains of an animal, supposed to have been an ichthyosaurus. 
The fossil is described as imbedded in the alum rock, the skull 
being entire, and measuring two feet ten inches long, one foot 
in breadth at the broadest part, and tapering to a point like a 
bird’s beak ; the jaw bones have been twisted, the teeth broken 
and displaced, and the remainder of the skeleton is much muti-~ 
lated and imperfect. It is supposed that the animal must have 
been at least 14 feet long. 
A paper was read, from H. T. De La Beche, Esq. on the rocks 
with their fossils of the coast extending from Bridport Harbour, 
Dorset, to the eastern point of Torbay, Devon. 
The line of coast described, begining at its western point, 
consists of the following beds which dip eastward. 
1. Rock marl, or red conglomerate ; this, at Axmouth Point, 
og gradually into the lyas, which dips below the surface a 
ittle to the westward of Bridport Harbour ; on this rests, 
2. Green sand, which is found first covering only the tops of 
the hills ; but on proceeding eastward, forms a continuous bed, 
and is surmounted at Axmouth Point by the 
3. Chalk, into which the green sand sometimes passes ; but 
the author has never observed the green sand passing into any 
inferior bed ; on ali the hills capped with green sand are found 
quantities of fragments of flint and chert, in some instances 
eae together by a silicious cement forming a breccia. 
)f the fossils, the author gives a partly descriptive catalogue, 
with some drawings,
