stations from the woods of the interior of Peru, Bolivia, and New 
Granada. Seeds and plants were often promised hy one and ano- 
ther, but these promises were not realized, although they were con- 
tinually renewed. It was sufficiently clear that the only means to 
obtain seeds or plants of the Quinquina-tree was to send thither a 
proper person to fetch them. 
** To find such a person was not easy. Various knowledge, bo- 
tanical knowledge, and particularly an acquaintance with the Quin- 
quina, were required. A great constancy and intrepidity in danger 
and in the difficulties of long journeys in foreign countries, and es-

Hasskarl, late Botanist of the Botanical Gardens at Buitenzorg, Java, 
on the mission. 
" The choice of so competent a man may in all respects be con- 
sidered fortunate. Mr. Hasskarl, by along residence on the Island 
of Java, had become accustomed to the influences of a tropical cli- 
mate. He had a strong constitution, and was of middle age. For 
many years he had given evidence of a great love for the science, 
and a comprehensive knowledge of the Flora of Java. His nume- 
rous published writings evince great accuracy, perseverance, and
