153 
inches of the hard calcareous sandstone bed, and it was not 
until excavations had proceeded some length that its extent 
and thickness were exposed. It was then found that a deep 
channel divided this rock into two, exactly on the line chosen 
for the railway, and that the channel was filled with sand 
easily excavated, in marked contrast to the sandstone rock, 
the removal of which proved such an arduous undertaking. 
As the sand was removed, the deep channel which it filled was 
exposed to view, and its remarkable features at once became 
evident. It was shortly after its complete excavation that the 
Club visited the section, and photographs were then taken. 
These show the sides of the channel (which varies in width 
from 6 feet to 15 feet or more) standing in relief; the rock 
worn into rounded bosses of various sizes, while in some cases 
huge mushroom-shaped masses stand isolated on the underlying 
sand. The largest of these is now placed in the garden of the 
_ Royal Agricultural College. On the cutting being cleared out, 
it was apparent that the sand was very regularly stratified. 
The sand, which was very loosely compacted, contains 1 per 
cent. of salt. The rock weathers very rapidly. Doubtless some 
of the sand which fills up the channel was due to the disin- 
tegration of the rock itself. The Professor inclined to the 
belief that we have here an old shore line of the Mid-Oolitic 
Sea, then slowly sinking, and silting up with its many-coloured 
sands. 
Drawings of the cutting, a detailed section, microscopic and 
other specimens, illustrative of the paper were exhibited. 
The Fourth and last Winter Meeting of the season was 
held at the 
SCIENCE SCHOOL AT GLOUCESTER, 
On Tuesday, the First day of April in the present year. Mr 
_ Locy occupied the chair, in the absence, through illness, of the 
_ President. 
Francis Day, Esq., F.L.S., read a paper on “ The Breeding 
_ of Fish.” After referring to the difficulties of the subject, and
