ing close to the Linden. On calling at Professor Braun’s I learned 
that he was in Brandenburg, happily away from the heat and 
crowd. Never before have I so suffered with the heat, which for 
six days has been intense; so great that walking was almost im- 
possible, and the dust made the riding almost insufferable. The 
crowd has been growing greater and greater, but culminated last 
night when there was a serenade by seven hundred musicians in 
front of the palace. I think I should enjoy Berlin in winter, but 
now I am tired of the heat and dust,and emperors; and shall 
leave at once for Cologne on my way to Strasburg.

New German Boranicat Manvats.* —The two botanical text- 
books named below have now superseded all others in Germany. 
The first, uniform with`a zoology by the same author, is admira- 
bly adapted for schools and colleges, being compact, clearly and 
concisely written, and copiously illustrated with woodcuts. All 
the subjects of any general botanical interest are touched upon, 
and, for this reason, it is an excellent book for amateurs who wish 
to keep up to the present state of the science without taking the 
time and trouble necessary for learning, practically, microscopic | 
and systematic details. The greatest ea in botany, recently, © 
has been made in the departments of anatomy and lower crypto- 
gams where, unfortunately, more knowledge of the microscope is 
necessary than is possessed by the majority of botanical readers. 
In the book of Thorné, the frequent woodcuts take the place of 
microscopic work as far as such a thing is possible. On the 
_ Whole, this is the best a botanical text-book which has 
gm been published in Germ 
_ The second work, Priam ee a text-book, partakes sol 
more of the character of an encyclopedia. In consequence partly 
of the high reputation of the writer as a vegetable physiologist, the 
book has had an “almost unprecendented sale, the third edition 
ae being already nearly exhausted and a separate edition of the 
Second mk relating to vegetable physiology, having just made its
