from these operations, but it was rendered impossible to 

 estimate them, by reason of the prejudice and ignorance of 

 the fishermen, who failed to send notice to Mr. Baist of 

 the marked fish recaptured, so that the proportion of fry 

 that returned to the river as grilse and salmon could 

 not be computed. Thus, one of the most valuable sta- 

 tistical results of the experiments was altogether lost; a 

 fiict very much to be regretted. Many most interesting 

 and hitherto debatable points in the natural history of 

 the salmon were also cleared up in the course of the 

 experiments, and science owes a debt of gratitude to the 

 conductors of them. To those who desire a compendious 

 and circumstantial history of these operations, I recom- 

 mend strongly Mr. Brown's little work upon the Stor- 

 montfield Experiments, which is a valuable contribution 

 to the natural history of the salmon.
