likely that the figures express a real difference between the two sets of samples. The 

 difference cannot, however, be called great, as presented in these comparisons. 



Comparison with the sample from North Sydney, and with the exceptional sample 

 from St. Georges bay. Table 42 shows the total averages for the samples from Mag- 

 dalen islands compared with the averages for the above-mentioned samples, which, in 

 contrast to those from the Northumberland strait, both exhibit a greater t^ than the 

 Magdalen islands samples. Otherwise, there is a not inconsiderable degree of similarity 

 in regard to growth. 



Table 42. — Growth of herring from Magdalen Islands and North Sydney and St. 

 Georges Bay divergent sample compared. (Year-classes 1903 for Magdalen 

 Island, 1903 + 1904 for the other localities compared.) 



The comparison with the older fish from the Atlantic coast is interesting. Table 

 43 shows the samples from ]\Iagdalen islands compared with the thirty-four specimens 

 of the 1904-03 year-classes representing the samples from West Ardoise and Lockeport. 



Table 43. — Growth of herring from Magdalen Islands (year-class 1903) and Nova 

 Scotia herring (year-class 1903 + 1904). 



The differences here are more marked than those found in the previous comparisons, 

 four out of the eight amounting to over four times their respective errors. Bearing in 

 mind, moreover, the fact that all average values are higher in the case of the Atlantic 

 fish than the corresponding values for the Magdalen islands samples, it will be realized 

 that the difference in growth is here bv no means inconsiderable.
