the principles of a new science, when the sad accident 
occurred by which his life's thread was severed. It is 
futile to wonder what he might have accomplished for 
Science had he lived to complete life's normal span; 
what he did achieve in his brief day was great and 
wonderful. Hence it is with pride that his fellow-country- 
men of the present day may remember that he signed

than fitting that a simple tribute of homage be here- 
with paid, on the occasion of the 200th anniversary of 
his birth, to one whose name will ever constitute a fair 
and glorious memory in the annals of scientific research 
in Sweden.
