lb. 14 oz. ; and another for comparison, April 

 27th, 1896, measured 17 Jin., wgt. 2 Ibs. 



e. Of course the comparative measure- 

 ments and weights of trout in condition vary in 

 different streams. All we have given here are 

 of Deveron trout. It is important also, of course, 

 when taking and recording such details, to keep 

 accurate note of the dates; and it might, and 

 we believe would, add to our knowledge if they 

 also tabulated descriptions of the weather at the 

 time they were caught. Those which we have 

 given can be compared with our previous remarks 

 and the other Tables given. 



It would be, we think, desirable if a 

 much larger series of measurements and 

 weights for different rivers were recorded 

 in sportmen's registers, 1 and at different 

 seasons say March, April, May, June, July, 

 and September. Only by a long series of 

 these could positive scientia be attained, 

 and much useful data for comparisons be 

 accumulated. We would be pleased to re- 

 ceive such from different rivers with a view 

 to future investigations. 



1 Registers, such as we use ourselves, can be obtained 

 from Messrs. Stewart and Co., stationers, George Street, 

 Edinburgh, bound in pads, or in sheets.
