The opportunity was taken at the trawling excursions to mark 
with numbered labels certain of the fishes captured, and more 
especially plaice. Altogether 48M fishes were measured — the 
majority weighed — labelled, and returned to the sea. A few have 
been re-captured near to the places where they were liberated, but 
one of the plaice had migrated from Goswick Hay to St. Andrew’s 
Hay. 
The measurements and weights have been utilised for making a 
chart to indicate the relation of size to weight in the case of the 
plaice. 
Another experiment as to the migration of crabs will be found 
interesting, for it goes to show’ that the migration of this form is 
not so simple as has hitherto been supposed. One of the labelled 
crabs migrated from Beadnell to the north of Holy Island, and 
another so far north as Portlethen on the Kincardineshire coast of 
Scotland. 
kir. Douglas, to whom we owe our thanks for this experiment, 
and Mr. Faw'cus, have again given us complete records of their crab 
and lobster fishing for the year. 
The Report contains a further paper by Mr. E. P. Witten, B.Sc., 
on the structural changes accompanying, the ecdysis of the crab, 
in wdiich he shows that growth by hyperplasia takes place after 
ecdysis, and ceases wuth the hardening of the new cuticle, and also 
that the internal pressure necessary for the ecdysis and the subsequent 
growth is furnished by the ingestion of a large quantity of .sea water. 
An account of our local Marine AlgiU, w’hich are so important as 
being the ultimate source of the food supply of the fish, is given by 
Mr. W. H. Young, F.Z.8. A note on a few additions to our list of 
the Marine Mullusca is contributed by !Miss M. Y. Lebour. I have 
described the egg of a species of Goby, and the results of my 
enquiries as to the presence of Gammanis dnebeni in the Mill Pit 
at Blyth. I also give notes on new and rare fishes, and on the 
Beluga captured at South Shields. 
Mr. F. .J. Cole, of the Liverpool University, sends me the follow- 
ing with reference to his work here in August : — 
“During last August I spent some time at Cullercoats with the 
object of collecting material of Myxine. In this I w’as entirely 
successful, and as every other source of supply had failed, I have 
much cause to be gratified for the existence of a marine laboratory 
at Cullercoats. I obtained a considerable quantity of small and 
adult Myxine, the study of which has since yielded many valuable
