instructive object in connection with the plant. Stahl did not 
know who had made them, but he had seen them nowhere 
else. The university was established 400 years ago. With 
such a line of ancestry, the professors and students may well 
feel a pride in their surroundings. 
“The botanical museums are far below the zoological and 
other collections, both in cases, arrangements, and in exhibits. 
Willrock’s in Stockholm is far ahead. There would be a 
magnificent opportunity to form a botanical museum that 
might compare with museums in other departments. There 
seems to be often a lack among botanists of the virility that 
influences zoologists and the other naturalists. ... 
“It occurred to me, from what I had seen in Kny’s labora¬ 
tory of injecting with colors, that flowers might be colored by 
this means before placing in alcohol. It might be possible to 
use insoluble colors, or colors that would not be dislodged from 
the cells. I got one very excellent idea from Stahl. He has a 
large tin box, made with double sides and tops and back 
containing water which can be heated from below with a gas- 
jet. It is a very large water-oven. Above can be inserted a 
thermometer to gauge the temperature. There are double 
doors and no means of admission of light. In winter time, 
by this means plants are germinated very rapidly. The tem¬ 
perature is kept quite constant. 
“It is a great invention and would supply a need in germi¬ 
nating seeds for lecture-illustrations, etc., and would also an¬ 
swer for obtaining plantlets for chemical study. A glass case, in 
addition to this, which could also be heated by hot water from 
underneath, would enable a student to carry out, in his own 
room, important investigations. This is where my trip has been 
of such infinite service in giving me an insight into methods 
and ideas for my own study on a small scale. The botanical 
gardens in connection with all botanical schools are of great 
importance to the student. The hothouses supply the plants 
from tropical climates. The temperate and cold houses those 
from other climes, and the out-door beds contain the hardy 
plants and annuals.”. . .
