 lands like treasures to the museum of the University. 

 These it became his business to examine, describe,

 a long series of publications, which contain articles 

 pertaining to chemistry, mineralogy and zoology, al-

The impression produced by such achievements 

 an impression that has not yet spent its force, but 

 continues to inspire and stimulate scientific research 

 in new lines and channels all the world over was 

 then felt far and wide amongst his contemporaries in 

 Europe. By reason of his presence at Upsala, the 

 number of students in the University rapidly rose 

 from 500 to 1500. And the attractive power reached 

 beyond the Atlantic, for, in a list of a party of seven, 

 who under his leadership made an expedition into the
