Ardrishaig, September 15, 1905. 



These herring were very small, the average length of six females being 

 20cm., and the average weight 80 grammes. The weight of the ovaries 

 in these six herrings was 5*70 grammes weighed in the fresh condition — 

 that is to say, the average weight per fish was -95 grammes. The ova 

 were very immature, varying in size from 15mm.--45mm. 



The male herrings had approximately the same measurements, the 

 average length of eleven being 20cm., and the average weight *75 grammes. 

 The testes from these eleven herrings weighed 10*65 grammes in the fresh 

 condition, i.e., *97 grammes per fish.

October, 1905 (Loch Fyne). 



Some of these herrings were in rather a more mature condition than 

 others, and so the females have been divided into two series for analysis ; 

 first, those with ovaries containing ova of about -28mm. in diameter, and, 

 secondly, those whose ova averaged -59mm.
