of Vallorbe, who had a collection of three thousand 

 specimens. While at Neuchatel he made a careful 

 study of the fishes of the Swiss lakes, making dis- 

 coveries that attracted the attention of the scientific 

 men of Europe. He made an extensive collection of 

 fishes, preserving some in alcohol, while others he 

 mounted, his work being distinguished for its excel- 

 lence. He also made many corrections in the classi- 

 fication of fishes. Fishes that had been named 

 twice he carefully noted, and one of his papers writ- 

 ten at this time contains a list of all the fishes he had 

 found and the lakes from which they came, while 

 other papers of equal interest showed the most 

 unflagging enthusiasm.
