randum p. 76—78 Tables la &b, Ifa). Strictly speaking, therefore, the measurements 
sent in are not quite applicable to the quantities of “small” landed in the autumn 
and winter months. Again, the measurements refer mostly to the eastern parts 
of the North Sea, “small” plaice landed from other parts of the North Sea and 
the Channel etc, are not represented. Further, the quantities taken account of 
here are only those landed by the largest class of boats, and though the quantities 
landed by the smaller boats amount to less than 0:1 % of the total quantities 
landed, they probably consist of “small” plaice only. 
Holland: The Dutch material has been the easiest of all to deal with. 
The published statistics of Ymuiden, Helder and Harlingen state very clearly the 
quantities of large, medium and small plaice lahded from the North Sea, and 
measurements regarding the “small” have been received for both Helder and Ymuiden. 
representing each month of the year. From information received from Dr. Repekr, 
the classes of plaice at Harlingen are the same as those of Helder, so that the 
measurements for the latter port could also be taken to represent the former. The 
plaice landed at Ymulden are divided into classes containing larger fish on the 
average than the corresponding classes at the other two ports. At Ymuiden, four 
classes are distinguished, measurements of the fourth or smallest class only being 
sent in to the Bureau. According to the information received, the third class 
(“kleine Schol. I’) contains no plaice under 27 cm., and this class corresponds to 
the larger class (“middel Schol”) of Helder and Harlingen. It has therefore been 
possible, from the measurements sent in, to estimate the proportions of plaice 
under 20 and 26 cm. landed at these ports during 1904 with very approximate 
accuracy, but not those under 30 cm. or larger size. 
The statistics for 1905, however, begin for the first time to give data con- 
cerning the plaice landed at Amsterdam, Rotterdam, Scheveningen and Katwyk 
on Sea. Until the whole year'is completed, it is clearly impossible to estimate the 
quantities landed at these ports. The quantities of small plaice given for Holland 
in Tables III & VII are therefore somewhat smaller than they should be. 
Germany: Measurements of plaice have been obtained from Geestemünde, 
Hamburg and Altona, with a few samples from Bremerhaven. The material for 
Geestemiinde represents the landings of steam-trawlers almost entirely, dei for 
Hamburg and Altona both steam- and sailing-trawlers. 
The market-statistics of Geestemtinde and Bremerhaven distinguish 
two classes of plaice, viz: large and medium together and small. It might be 
thought an easy matter, therefore, to ascertain from these and the measurements 
sent in to the Bureau the proportional quantities of plaice under certain sizes. It 
appears, however, that the fish when sold on the market are divided into many
