STOEMONTFIELD. 255 



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. Buist 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 statistical 

 results of the experiments was altogether lost, a fact 

 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 experi- 

 ments, and science owes a debt of gratitude to the con- 

 ductors of them. To those who desire a compendious 

 and circumstantial history of these operations, I recommend 

 strongly Mr. Brown's little work upon the Stonnontfield 

 Experiments, which is a valuable contribution to the 

 natural history of the salmon.
