power and clearness of the microscope and the more organisms he could 
distinguish. Sixteen years before Professor Phillips published a 
description of lacustrine deposits, a quarter of a mile north of 
Bridlington ; but until within a few years his microscope was in- 
adequate to the research. He had recently repeated his examinations, 
and had found a considerable number of loricated infusoria, five 
species of the genera Navicula, Cocconema, Bacillaria, and Eunotia ; 
he had also discovered a new species of the rare genus Campilodiscus 
in this marl. Specimens of Gaillonella, Lyxidicula and Sydenera were 
also found. It appears from the researches of Ehrenberg that the 
Bridlington species are nearly all living at the present day, and 
though he considers it somewhat difficult to be assured of this perfect 
identity, still observation appears to agree in the statement that no 
clear or certain mark of distinction between the fossil and recent 
specimens can be distinguished. 
Mr. William West, F.R.S., at the same meeting exhibited a 
number of experiments, illustrating some peculiar states of water at 
high temperature, and upon the freezing of water in red-hot vessels, 
and the Rev. Dr. Scoresby gave extemporaneously his observations 
on the currents and phosphorescence of the Atlantic. The Reverend 
gentleman was also present at the evening meeting and contributed 
observations on the falling or shooting stars at Rheims and Paris, and 
other subjects which had been dealt with at the previous British 
Association Meeting at Cambridge. Mr. Henry Denny then read a 
paper on the fossil animal exuvia of the Yorkshire Coal-field. After 
noticing the abundance and elegance of its fossil plants, he remarked 
that the remains from the animal kingdom were very rare, but that a 
many ichthyological specimens had been obtained. The first well- 
authenticated remains of fish were the heads of Megalichthys, from 
the Low Moor and Waterloo Collieries. The highest class of verte- 
brate animals found in the coal measures is that of fishes. On the 
Continent, between Coblentz and Cologne, there is a brown coal 
formation, or as it is termed paper coal, of more recent origin than 
our coal measures, in which are found, besides fishes, batrachian 
reptiles. In the Yorkshire coal measures we cannot lay claim to any 
quadrupedal or reptilian remains. The fishes occurring are mostly
