the effect of legislation in promoting the increase of fish in our 
rivers and inland waters, Mr Day proceeded to describe the 
migrations of fish, the mode in which the ova are deposited, 
and the care with which they are watched over by the male 
fish. He gave an account of some experiments made in the 
artificial breeding of fish, which showed that different species 
of the Salmonide may be successfully crossed, but that expe- 
rience has yet to ascertain whether the progeny will be sterile 
or fertile, stationary or migratory in their habits. Experiments, 
he stated, are being assiduously carried out in Scotland by a 
single public spirited individual, at his own cost. The United 
States Fishery Commissioners have demonstrated how sea fish 
can be artificially hatched as readily as those from fresh waters: 
while the Fishery Department of the United Kingdom give no 
assistance and contribute in no degree to investigate the subject 
of fish culture. 
Mr Lucy exhibited a large piece of pumice, which fell, red- 
hot, on the deck of the Italian barque “‘ Padre Francesco” 
during the eruption of the voleano Krakatoa, in the Straits of 
Sunda, in the month of August last. The vessel was distant 
about three miles from the volcano at the time. This “drop of 
the crater” has been presented to the Gloucester Museum by 
Mr E. V. Exuis, the Italian Consular Agent. 
Mr Lucy then read a Paper on the sinking of a well at 
Messrs Roserrson’s brewery, which was illustrated by a care- 
fully prepared Section. The well was sunk in the expectation 
that at the depth of 200 feet the Rhetic beds would be reached, 
but the test of boring, which was made to the depth of 350 
feet, showed that at least 80 feet more would have to be passed 
through before the Rhetics were pierced. Mr Lucy had been 
consulted prior to the sinking of the well, and, in referring to 
the error he had made in his calculations, gave his reasons for 
believing that the Rheetic beds were nearer to the surface than 
they had proved to be. These reasons were founded upon 
a knowledge of the surrounding Geological conditions with 
reference to the Rhetic beds as established at Highnam, 
Wainlode, Elmore, and other points in the neighbourhood.
