268 FIRST JOURNEY IN EUROPE. [1839, 
TO WILLIAM J. HOOKER. 
Lonpon, September 13. 
My pear Frrenp, — The “ penny postage system” 
not being yet in operation, [ embrace an opportunity 
that offers to send you a line in Pamphlin’s par- 
cels. I am again in London, you see; indeed I have 
been here about a week. But it is only to-day that I 
have had intelligence of your return to Scotland. I 
had some hopes that I should find you in London on 
my arrival, or that you would return here from 
Chatham, and that I should have the gratification of 
seeing you once more. I received your welcome letter 
of August 14th, at Berlin, for which I thank you much. 
I wish my friends at home were half as prompt cor- 
respondents. While on the Continent I have received 
precious few letters. 
I have been much interested at Berlin, and worked 
hard. The herbarium of Willdenow is larger and in 
better condition than I supposed, and the gen- 
eral herbarium is very interesting and rich. Klotzsch! 
is very industrious, and has got the whole collection in 
much better order than most of the herbaria on the 
Continent. I am under great obligations to Dr. 
Klotzsch, who not only afforded me every facility at 
the Herbarium, but most cheerfully aided me in every 
possible way, and during a transient illness (for I 
was confined to my room for a week or so, and to my 
bed for a few days) he procured for me the best med- 
ical advice, and took a great deal of trouble on my 
account. 
I lost some time by this, but fortunately I had nearly 
finished my work at the Herbarium, and afterwards

at Berlin.
