• Dr. Peter Jonas Bergius was professor of natural history in the university of Stockholm, and died 

 in the year 1790. He was the author of a Description of several African Plants from the Cape of 

 Good Hope, and of some other papers ; but his principal work is his Materia Medica, (Stockholm, 

 177t<. 8vo,) In this work the several articles belonging to the vegetable kingdom are arranged ac- 

 cording to the Linnaean system, and their medical qualities detailed with great accuracy and judg- 

 ment; rendering it a truly meritorious publication.
