THE SUTTON BROAD LABORATORY. 
It will be seen at once that in such a district there is no field 
for the work of the kind, which figures so largely in the reports 
of freshwater Biological stations on the Continent and in America. 
There is neither a pelagic nor a deep water fauna ; there is only 
“pond life,” and of that there is an abundance in species and in 
individuals, both of plants and animals; moreover, this water system 
presents so many and so various features (especially as regards 
salinity) that we may expect to find a remarkable distribution 
adapted to the varieties of environment. 
The aims of the Laboratory are, first of all, to make complete 
lists of species to be found in the district, taking group by group, 
with exact notes of the spots and the months in which each is 
found, and observations upon the physical conditions. This is 
a large work, and can only be done by the collaboration of many 
workers. It is thought that interesting results may be obtained 
by recording the changes in distribution year by year. Concurrently 
with this, which may be called the general work of the Laboratory, 
more special work will be undertaken in the direction of com- 
parative anatomy and life history. 
During the past year, Mr. Balfour Browne and Mr. Robert Gurney 
have been continuously at work in the Laboratory ; the former has 
investigated the distribution of the Dragon Flies, and the latter the 
distribution of the Copepods and Cladocera. Mr. D. J. Scourfield 
and Mr. W. R. G. Bond have paid short visits for the purpose 
of studying the Entomostraca, and Mr. F. J. Hanbury has made 
collections on the Broad. A large collection of Hydrachnids is 
being made and sent to Mr. G. D. Soar for identification. Besides 
the Zoological work, observations are being made on the move- 
ments of the water, the salinity, temperature, etc. This summer 
the marking of fish is being undertaken with a view to tracing 
their movements and rate of growth. 
It is much hoped that this year more workers will make use 
of the Laboratory ; and for the information of these it may be 
said that it is about two miles by road from Catfield Station, and 
within twenty minutes by water from Stalham Staithe. — Ed.
