AMONG the scientific men of Europe with whom 

 Professor Silliman occasionally corresponded for a 

 long series of years, was the eminent Swedish chem 

 ist, Berzelius. This correspondence began at the 

 request of the latter, a few of whose letters are given, 

 either entire or in extracts, below : 



(STOCKHOLM, July 13, 1820. 

 You cultivate a science to which I have de 

 voted the greater part of my time. It would be very pleas- 

 *ant to me if you could maintain a literary correspondence 

 .with me. I cannot promise you that my letters will have 

 the same interest as those of an inhabitant of France or 

 England ; but, as we are not entirely confined to Sweden, 

 I can perhaps from time to time furnish you with interest 

 ing news.
