been reared by himself, and which weighed 2 Ibs. He had seen 
some thousands or tens of thousands of char taken from that lake, 
and never yet saw one which would turn the scale at half-a-pound. 
The common size, he thought, was five to the pound. Although 
he had heard of much larger fish being taken, they were very rare. 
These fish could be taken from Windermere, and in a few genera- 
tions grown to the size of the one exhibited. He had grown them 
up even to 3 lbs. 
Mr Amnistead next alluded to the despatch of salmon ova to the 
Antipodes from this country by Mr Frank Buckland and Mr Youl, 
and also from America, and to the large proportion of loss caused 
by the hatching of the eggs during the voyage. It had since been 
discovered that by subjecting them to a low temperature hatching 
could be so retarded that they could be kept for a long time. He 
had himself adopted this process successfully in the case of ova 
taken from the Nith and exhibited at the Fisheries Exhibition in 
London. He next spoke of the improved results obtained by 
hatching the ova on glass grilles, which prevented contact with any 
deleterious substance, and expressed his preference for either glass 
or slate over metal, even when varnished. 
Passing on to speak of the American trout, Mr Armistead 
said this fish was really a char. They had been introduced into 
this country for about twenty years. He got aconsiderable supply 
of ova, and the fish had passed through a great many generations, 
and been considerably improved in that time. He exhibited a few 
recently hatched fry, some of the ova, and a bottle containing two 
little double-headed fry and several others deformed in various 
ways. Peculiar forms, he explained, could be produced by 
pressure applied to the ova. The two-headed ones were the 
produce of what might be called double-yoked eggs. The American 
trout had been a good deal run down by some people ; and one 
reason for that, he believed, was that wherever he had been put 
into rivers or lochs from which he could escape, he had done so 
and gone away to sea. There they attained to a considerable 
weight. Instances were recorded of them being taken of eight, 
ten, and even twelve pounds. The very fact that the fish would 
leave fresh water and go to sea was one strong proof of its value. 
One reason why we had been unsuccessful in stocking the large 
rivers with it was that we had not put in sufficient. In America 
it was quite a common thing to turn ten or twelve millions into 
a river in a season. Here, he believed, the largest known stock
