A comparison of these results with those of the female unspawned 

 fish of 1896 shows the following : 



1. The muscle of the kelt contains a smaller percentage of proteid 

 than all the unspawned fish except those from the upper waters late in 

 year. 



2. The total amount of muscle nitrogen per fish of standard length 

 is less than that of the unspawned fish, the same late upper- water 

 unspawned fish being excepted. 



3. The percentage of proteid in the ovary is less than in all unspawnod 

 fish. 



1. The total nitrogen per fish of standard length in the ovary is less 

 than in all unspawned fish. 



It will be seen in the Tables that out of the four fully analysed kelts 

 three have more nitrogen in their muscle than the upper-water fish of tl 

 later months of the year. There are two explanations of this, the one 

 that they represent not the late upper-water fish, but the late estuary
