PRESENT STATE OF THE GRIMSBY TUAWL FISHERY, 411 



In the present edition this item will be found to have been altered in 

 accordance with the actual conditions, the amount subtracted being 

 divided between the three months in proportions which correspond 

 roughly with the relative abundance of Iceland fish during the period 

 concerned. The figures 49,000 in column i were a misprint for 41,000 

 — the Board of Trade total. A further error appears to have been 

 made in the number of boxes for June, 1893, and this has accordingly- 

 been altered to the number originally published in the Journal of the 

 Association, vol. iii. p. 124. 



The table on p. 410 (Reprint, p. 74) is dependent on the calculations 

 in the former table, and is therefore vitiated by the errors alluded to. 

 It happens, however, that the revision of this table only brings into 

 greater prominence the destruction of undersized fish. 



My attention has recently been drawn to the absence of any 

 definite statement in my text as to the method by which the averages 

 of number of fish in boxes of different qualities were deduced. At 

 this lapse of time I regret that I am unable to lay hands upon the 

 original figures, and can only state that I deduced averages from the 

 contents of a large number of boxes of each quality counted during the 

 earlier period of my work, and checked the results so obtained from 

 time to time during the later years; and in order to run no risk of 

 exaggerating the proportion of undersized fish, I actually made use 

 of averages which somewhat underestimated such proportion. 



It remains for me to express my indebtedness to the Association for 

 publishing this corrected version of my tables (which my own circum- 

 stances did not allow of my undertaking), and to Professor Weldon and 

 Mr. E. J. Allen for tlie revision of my figures.
