few hauls made in September in the same region, but further north— 
about sixty-five miles to the south-east of Sumburgh Head, the general 
average for all sizes was 6:9; that for cod was 110, for large codling 
88:5, and for small codling 0:0. In October about twenty miles south- 
east of Fair Isle, in sixty-five fathoms, the average for all sizes was 
9-5; for cod it was 1:9, for large codlings 7:4, and for small codlings 
0:17, the respective percentages being 19°7, 78:4, and 1:9. In the 
following Table I give these figures in comparison with those for 
Aberdeen Bay and the Moray Firth when the month is comparable :—

Examination of these figures shows the variations in the different 
areas at the times. Considering first the totals, it will be noticed that 
the average is highest on the offshore grounds with the exception of 
Aberdeen Bay in October. Cod were more numerous in the deep 
water in each of the months except May in Aberdeen Bay, and 
relatively more so in June in all the areas than in any of the other 
months. In September and October the average was the smallest in 
Aberdeen Bay and the Moray Firth, and it was low in the deep water. 
The averages show the absolute abundance, but the percentages, which 
show the relative numbers of the three classes, also indicate a prepon- 
derance of the adult fishes in June, compared with the other com- 
parable months.
