reaches a height of about 90 feet, being the highest one yet con- 
structed, and too high for satisfactory operation. The botanical 
museum is very extensive and has series of economic, systematic 
and archaeological collections. The herbarium is one of the 
largest in the world. The systematic beds are arranged on a 
strictly modern sequence, and portions of the garden are devoted 
to plant geography and plant biology. The arboretum is not ex- 
tensive. Among special features may be mentioned the alpine 
garden and the collections of Cacti. The garden is an institute of 
the University, where the principal laboratories are situated. There 
is also an institute of plant physiology with a small separate gar- 
den. The official publications of the Berlin Garden are the 
“ Notizblatt” and annual reports. A series of volumes of “ Jahr- 
biicher” was issued some years ago. The publications of the 
garden staff are voluminous and cover all lines of botanical inquiry. 
4. The long-established “ Jardin des Plantes,” the gardens of 
the Museum of Natural History at Paris, are situated in the heart 
of the city, fronting on the Seine. The conservatories are grouped 
near the main museum building at one end of the grounds, are 
very large and contain a great variety of plants. The botanical 
library, laboratories, and the enormous herbarium are in a sepa- 
rate older building. The systematic beds are arranged in rows; 
‘owing to the limited size of the area devoted to them, they are 
much crowded, but contain a splendid assortment of species. 
But little space is given to trees; there are, however, some famous 
specimens. Many valuable contributions to the literature of 
botany along all its lines have emanated from this grand institu- 
tion for over 100 years, published for the most part, in the “ An- 
nales” and “ Archives”’ of the Museum of Natural History, and 
in the Bulletin of the Botanical Society of France. 
5. The Botanical Garden of the University of Vienna was 
established about 1754, and is located in the heart of the city. 
_ There are here very important and extensive museums, herbaria 
and libraries, and one large fine greenhouse. The systematic 
plantations occupy the larger portion of the tract, and special 
areas are devoted to the cultivation of medicinal and other eco- 
nomic plants, to an arboretum of native trees, and to groups illus- 
trating plant geography. The garden and associated laboratories
