Appendices to Thirteenth Annual Report 



June the rate of growth is very slow, in the earlier months almost imper- 

 ceptible, but from July onwards an ever increasing energy of growth is 

 maintained. Fittingly enough the last fish examined on the last day of 

 November was spawned out, but from 24th to 29th November four ripe 

 males were taken, as noted in Table I. A perfectly ripe female was not 

 obtained. The genital organs of the male grilse appear to grow at nearly 

 the same rate as those of the male salmon, while the ovaries of the female 

 grilse lag a little way behind those of the female salmon. 



My best thanks are due to Mr Steel, fishdealer, Kelso, for his uniform 

 kindness in affording me every facility in examining his fish.
