THE VOYAGE OF H.M.S. CHALLENGER. 
which he spent at Bonn was devoted to Anatomy and Natural History. At the end 
of this time he went to Munich to devote himself entirely to the study of zoology under 
Professor von Siebold, who was always the warm friend and judicious adviser of the 
young zoologist, and received from him in return a sincere veneration which ended only 
with his life. 
His letters at this period express much contentment ; he felt very happy, and 
worked with ardour to distinguish himself ; but although so occupied that he once 
playfully wrote to his sister — “ Alles was ich treibe interessirt mich lebhaft, nur 
habe ich so unglaublich viel zu thun, dass sich abends, Bindegewebe, Fische, Ammoniten, 
Krebse, Frosche in wiistem Cancan mir im Kopfe drehen,” he yet found leisure to 
frequent society, which furnished him with a salutary change amidst his incessant 
studies. 
The year 1868 was marked by a visit to Venice, which he afterwards styled his 
“erste Vernunftreise,” and a sojourn at Berchtesgaden in the Bavarian Highlands 
with the von Siebolds, which furnished him with an opportunity of studying wasps. 
At Easter 1869 he left Munich for Gottingen, where he found the same friendly 
reception as elsewhere. After having continued his studies under Professors Henle, 
Meissner, Seebach, and Grenadier, he obtained his doctor’s degree in February 1870. 
Before his examination, however, he went during the summer vacation in 1869 for two 
months to Spezzia and Genoa ; a visit which gave him much enjoyment, and rich 
material for his scientific researches. In Spezzia he made the acquaintance of the 
Ma.rchese Andreas Doria, known by his travels to Borneo, Sumatra, and Persia. The 
Marchese was then building a splendid museum at Genoa, and during v. Willemoes Sulim’s 
stay there behaved very kindly towards him, showing him his treasures, and giving him 
much useful information. 
During a temporary residence at Kiel in 1870 he was introduced to Professor 
Kupffer (now in Munich), for whom Willemoes Suhm always professed the warmest 
regard and friendship; their intercourse was never interrupted till his death. In October 
1871 Willemoes Suhm returned to Munich by the advice of Professor von Siebold, and 
on the 1 8th December he was accepted as “ Privat Docent,” after having pronounced a 
thesis upon “Die rudimentarischen Organe und deren Bedeutung in der Thierwelt.” 
He then began his lectures, and enjoyed the friendly support of both professors and 
students. During his sojourn in Munich, though always devoted to science, he spent 
many happy days in Possenhofen at the house of the Duke Carl Theodor, who then 
took great interest in zoology. 
It was about this period that he felt an earnest longing to quit Europe and travel 
through foreign countries in order to enlarge his knowledge, and this wish constantly 
haunted him. In July 1871, he wrote to his mother: — “Ich fiihle dass ich hinaus in 
die Welt muss; einc Museums Existenz ware auf die Lange fur mich unertraglich. Ich
