Tables are also given showing the ratios which exist between the 
weight of the fish and that of the reproductive organs at different periods, 
and also those existing between the more important constituents of 
muscles and genitals.

These herring were very small, and, with one exception, contained very 
immature ovaries. One herring (No. 11) contained ovaries which 
weighed 14-75 grammes, and the ova which were present measured 1'2mm. 
in diameter and were being discharged. 
The immatnre ovaries, although they contained large numbers of very 
small ova, were evidently comparatively recently spent (see following 
pages for measurements and analyses).
