The younger herrings show the following: - The females, 215 in 
number, extend from 225mm. to 250mm. (81 to 9% inches), viz., to the 
point where fusion takes place with the older group; but if the curve 
is continued into the second group, as it ought to be to give the true 
limit, then herrings of this series will extend to about 26-5em., or 103 
inches—perhaps more. The modal size is 24:25cm., according to the 
‘Dem. arrangement of the measurements; according to the millimetre 
table it is at 244mm. (98 inches); the mean size is 237-5mm., or on 
the extension of the series to 26°5cm., it is 245mm., and the computed 
average is 239°9mm., or nearly 9} inches. 
The males number 256, ranging from 218mm. to 250mm (83 to 94 
inches, or further, as described for the females); the mode is 23-5cm., 
according to the ‘Sem. arrangement, and according to the millimetre 
table 237mm. (93 inches); the mean is 234mm., or, if the group is 
extended, 241-5mm. (94 inches), and the computed average is 236'7mm., 
or 9,°; inches. 
The figures for the two sexes grouped together are 471 herrings, 
ranging from 218mm. to probably 26:5cm. (82 to 103 inches), a range 
of 47mm. The modal size is 238mm. (9% inches), and the average 
237'7mm., or the same.
