PROCEEDINGS OF SOCIETIES. 
propagation of the turbot, the sole, and the codfish and haddock, could, with the same 
results, be accomplished from the spawn, as the propagation of the ova from the 
salmon or trout. 
The Chairman considered the subject brought forward was one of great value, not 
alone to the scientific man, but in a practical and economical point of view. He 
could confirm, withregard to the fisheries, how useful the formation ofthose store ponds 
would be. At the island of Inishtrahull, about six miles from Malin Head, off the 
coast of Derry, he had observed the islanders were prepared to bring fish to vessels 
passing the island. The fishermen of that island had very fine whale boats, which 
were sheltered and drawn up in a sandy creek. In a store pond, naturally formed 
in the island, the fish taken by them, such as turbot and other prime fish, were 
deposited, and they were always prepared to put fish on board the steamer passing 
from Sligo to Glasgow, or to Liverpool. 
Mr. Ffennell, commissioner of fisheries, observed that the concluding part of Mr. 
Andrews’s statement was one of great importance, and as it bore upon the 
artificial propagation of fish, he would take the opportunity of saying a few 
words as to what was doing in the salmon fisheries of this country. He had 
received a large quantity of the impregnated ova, and he had sent about 
30,000 to Mr. Cane’s, at St. Woolstan’s, for the purpose of carrying on the 
propagation in the Liffey. Mr. Ffennell said he had a large quantity of the 
ova, which he was experimenting on at the Custom-house, and he would, from time 
to time, present to the Society phials of the ova, showing the progressive develop¬ 
ment ; and he would further be most happy to assist any who were desirous 
of following similar experiments and investigations. Mr. Ffennel was also 
happy to say, that the young fry which created so much interest at the 
Exhibition, were thriving and growing well. A few days since he took one with a 
small net from the tank, of which he had an accurate drawing and measurements 
made. Its length was 4^ inches, showing the size of growth from the time he first 
got them in June. At that time they were barely an inch in length. If any of 
the members call at the Custom-house, it would give him much pleasure to show 
them. 
Mr. George A. Pollock said, that in the time of the Earl of Hardwicke, the Irish 
fisheries were considered of the highest importance; and it was remarked, in a 
correspondence, that it was one of the principles inculcated on the members at their 
election, that they should support the Irish fisheries. 
After some interesting discussion the ballot was declared, and James Haughton, 
Esq., of Moorfields, Roebuck, was elected a member. The meeting then adjourned 
to February.

PARASITIC (?) MOTH FOUND IN THE PUPA OF LASIOCAMPA TRIFOLII. 
In the course of the early summer of 1848 I found a caterpillar of Lasiocampa 
trifolii, in the vicinity of Oxford, which throve satisfactorily, and in due time 
entered the pupa state, having formed its cocoon in the regular compact oval form 
peculiar to it. Instead, however, of the imago appearing, as it should have done, 
in July or August, it continued in the pupa state the whole of the summer, autumn, 
and winter of that year, and also through the spring and summer of 1849. I then 
thought it must be dead, and opened the cocoon to ascertain the fact, when I found 
it not only alive, but quite lively, and apparently in perfect health. Having carefully
