In these Tables certain fish require special consideration. In the 

 estuary fish of May and June, Nos. 15, 17, and 29 were found to differ 

 so markedly from all the other May to August fish, that they were ex- 

 cluded from the general class. Nothing special is noted as to the 

 appearance of No. 15. In No. 17 the gall-bladder was found to 

 be empty, and in 29 there were no sea lice, and some old wounds were 

 present on the left side. In drawing conclusions from the table 

 it seemed better to exclude these fish, though their inclusion does not 

 invalidate any of the conclusions arrived at. 



In the estuary fish of October and November, Nos. 72 and 79 differ 

 from the others in the large amount of solids in the muscles and 

 the small development of the ovary. They are, in fact, examples of the 

 "winter salmon" of Miescher Ruesch, fish not going to spawn till the 

 ensuing season. They are, therefore, excluded from the general class. 



In the upper- water fish of May and June, one, No. 11, appears 

 abnormal, and it has been excluded in drawing conclusions. Its inclu- 

 sion would merely emphasise the distinction between the upper and 

 lower water fish. 



On taking the average results of this table we find the following :
