the perfect form, though small, of the adult animal was attained. 
At this stage, unfortunately, a fishing excursion obliged the 
abandonment of their personal charge for a few weeks, and during 
that interim the little animals died. Such, however, was the 
measure of success up to this point, that I feel convinced that, 
with intelligent superintendence and adequate appliances, the 
artificial culture of the lobster might, if systematically pursued, 
become a very highly remunerative commercial enterprise. This 
subject will also be prosecuted, and it is to be hoped to a still 
more successful issue, at the aquarium now constructing at Great 
Yarmouth.”

Great Blackbacked Gull and Missel Thrush—On the 4th 
I went to the sea-shore and saw nothing but a few great black- 
backed and common gulls. In coming home up the Dene my 
attention was drawn, by the harsh notes of some missel thrushes 
overhead, to a great blackbacked gull—mobbed by seven missel 
thrushes—flying inland up the Dene: one of them kept swooping 
so near at the gull as to leave me in doubt whether it did not 
actually strike it. The gull kept sailing on in a straight line, 
apparently taking little uotice of its assailants. After keeping 
up the attack for about a quarter of a mile, six of the thrushes 
wheeled back to some lofty trees, leaving one to continue the 
chase some distance farther: this was no doubt the old cock, as 
they were most likely one family. In the autumn and winter 
I often find them moving about in small flocks of from twelve to 
fifteen. I have only once met with a larger fock: I saw twenty- 
seven on the 7th of October last, and thought they had probably 
assembled preparatory to leaving us; I saw them, however, several 
limes up to the first week in December in the same locality, but 
not since. I am quite certain that the missel thrush is much more 
common in this neighbourhood than it was a few years ago. 
Roughlegged Buzzard.—On the 10th a female of this species 
was brought to me, which had been seen about the Dene for
