In the salmon stake-nets at Montrose 52 young turbots were taken in 

 May, June, and July, the measurements of which are given in inches in 

 the Table subjoined (2), and as near as possible in centimetres in Table 

 XVII. 



The greater number were obtained in May, viz., 30, while 17 were got 

 in June and 5 in July ; perhaps an indication that the young turbot move 

 further out with the rise in temperature. 



From what has been stated above, it is probable that the smallest at 4 

 inches (101mm.) are turbot of the preceding year and are approaching 

 their first year of age. Whether those at 4j to 4| inches (115mm. to 

 120mm.) in May are also fish of the preceding year, under one year of age, 

 is not so clear. The curve formed by the May measurements appears to 

 show the presence of four groups, and the first is separated from the 

 second by a deep division at 13cm (5J inches), and the second from the 

 third at 17cm. to 18cm. (7 inchsa) The figures, in centimetres, are as 

 follows : —
