FAUNA AND FLORA OF NORFOLK : ROTIFERA. 1 39 
Before I leave the subject of the actual work at the table, 
let me here express my gratitude and admiration for the 
comfortable and convenient arrangement of the laboratory. 
We amateurs who are used to working at a cramped little 
table in our own studies, can appreciate the professional 
arrangement which allows everything to be at hand without 
being in the way. 
The description of one day’s work will serve as a type of 
the general method which 1 pursued at the Laboratory. 
Starting out with a boat (another of the useful things pro- 
vided), a basket of big bottles, a pickle jar, and a small box 
of corked and numbered tubes, a telescopic walking stick 
into which the Rotifer net can be screwed, or the hook to hook 
up weeds as occasion requires, one drops the tow net overboard 
and rows off to a likely spot. The spot called The Heater on 
Sutton Broad was one of the first I chose, and turned out 
to be one of the best. 
On the way a sample of the produce of the tow net bottle 
is emptied into a tube (1) and the locality recorded, the rest 
is poured into a sort of pot pouri jar — No. 1. 
Arrived at the Heater, first of all a general sample of the 
free swimmers is taken and labelled tube (2). Then a bunch 
of weeds is hooked up, put into the pickle jar, half full of 
water, violently shaken and the contents strained into the 
Rotifer net. A sample of this put into a tube (3) and the rest 
poured into Big jar No. 2. More weeds arc treated in the same 
way until bottle No. 2 is filled. Then the tow net is dropped 
again, and we row off to another locality. The same process 
being repeated, care being taken to wash the rotifer nets 
thoroughly between two catches in order to keep the localities 
distinct. Two or three localities in one day are quite enough 
for one night’s work. 
Before leaving any locality, a specially nice piece or two of 
weed is carefully hooked up without being too much disturbed 
and put straight into the big bottle of that locality, and certain 
special weeds good for producing the fixed Rotifers are selected 
and put into the tinv tube of that locality. On returning 
to the Laboratory, carejnust be taken to uncork the tubes at
