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 tront. 



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, with regard to the fisheries, how useful the formation of those 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
