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. (f of an inch), and probably not much 

 over | 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 end 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.
