cate Roads, Druriclge Bay, and Blytli Bay its presence Las been 
dicated several times. The recent investigations to the north 
.id the south have shown that such a stage actually occurs, and it 
now obvious that the growth in this region must include it also, 
le restatement of the average growth of the plaice in the North- 
nberlaud district may be said to be approximately : — 1 year, 
cm.; 2 years, 13-5 cm.; 3 years, 22 cm.; 4 years, 28-5 cm.; 5 
i ars, 35 cm. ; 0 years, 40 cm. ; 7 years, 45 cm. The year is 
sumed to end on March 31st. 
Growth of the Dab. — A consideration of the measurements of 
e first haul shows that early in the summer, June, July, there is 
group of 7 to 8 in. or about 19 cm. In August, September, stages 
5 in. or 12-7 cm. and 9 to 10 in. or 24 cm. may be seen in some 
asons. But the larger groups, for reasons which have already been 
ated, are not so commonly present as in the case of plaice. These 
lints are taken in accordance with the method explained above, to 
present successive years' growth, and a trial curve joining them 
rms a basis upon which the actual growth of the marked fish may 
) mapped out. The growth of the dab during the first year is 
lown from the work of Cunningham, Williamson, and others, and 
lis serves to give the origin and early trend of the curve. From 
icse results it is now possible to deduce the average growth of the 
tb to be that stated in the following table. The year is assumed 
i» begin on 1st June.

A dab which I had in the Cullercoats Laboratory, got at Skate 
oads on June 20th, some years ago, measured 2 in. (5 cm.) and 
eighed (after being preserved in formalin), 1-02 grains. ' -035 oz. ) It 
•ust, therefore, have been just over one year old, and the weight of 
le dab at one year may be taken to be -03 oz. The weights for 
ie succeeding yearly stages are derived from the chart showing the 
Nation of length to weight. 
Growth of the Flounder. — Relatively few flounders are 
night at the trawling experiments, but at Alnmouth Bay especially
