of the Fishery Board for Scotland, 311 
In December, only four of this series were taken, viz., on the 3rd, and 
they measured 15mm, and 17mm. There were also four at 37mm., or 
almost an inch and a half, probably spring fish, as well as one at 
100mm., and another at 134mm. 
It seems probable, therefore, from these observations that towards the 
end of the year the average size of the young autumn herring, when three 
to four months old, is under 20mm. (# of an inch), and probably not much 
over 3 of an inch ; some measure 26mm., or slightly over one inch. 
The spring herring, which is, however, 1mm. to 2mm. longer when it 
issues from the egg, grows quicker, and may even reach, as we saw, a length 
of an inch at the ed of May, when they are relatively younger. This is 
associated with a favourable and rising temperature, and probably better 
food supplies, since M‘Intosh found traces of diatoms in them in March 
(25 g, 267), and also Dr. George Murray (26), who found Coscinodiscus 
abundant in small post-larval clupeoids. 
From these tables of Masterman it would appear that the growth of 
the herring in its post-larval stages is much slower on the east coast of 
Scotland than Meyer found it to be at Kiel.
