88 BENJAMIN SILLIMAN. 
Medical Chemistry and Toxicology in the Medical College at. 
Louisville, Kentucky, which chair he occupied for five years. 
“Louisville became for the time his place of residence. He 
relinquished this position in 1854 to enter uporf instruction in 
the Academic and Medical departments of Yale College, his 
father’s resignation having left the place vacant. His position 
as Professor in General and Applied Chemistry in the Aca- 
demic College he resigned in 1870, but retained his connection 
with the Medical School until his death. 
Tn 1851 Mr. Silliman accompanied his father on the latter's 
second visit to Hurope. During the time abroad the party 
visited England and from there traveled through France to 
Italy and Sicily. On the return some time was spent in Switz- 
erland and Germany. The journey was a profitable one in 
many ways. The former Huropean tour of his father, im 
1805-6, had been cut short by war which compelled a speedy 
retreat after a brief time in Holland, and it was a special delight 
to him now to visit regions of volcanoes and glaciers, which had 
been subjects of eloquent lectures by him for so many years, and 
to see face to face the men whose names he had so often quoted, 
and so long honored—Lyell and Murchison in England, Brong- 
niart, Milne-Edwards and Elie de Beaumont in Paris, Marigna¢ 
and De la Rive in Geneva, Humboldt, Rose, Liebig and others 
in Germany; and in this pleasure his son shared most pro 
foundly. . 
In 1858 Mr. Silliman had charge of the Chemical, Mineralog: — 
ical and Geological department of the Crystal Palace in New 
York. At this time he edited, in connection with Mr. ; 
Charles R. Goodrich, a large illustrated quarto volume entitled 
the “World of Science, Art and Industry ;” and, in 1854, 
another similar volume entitled ‘‘The Progress of Science and 
Mechanism.” : 
In March, 1864, he made his first visit to California, where, — 
for about a year, he was engaged in the professional work of .
