further enlargement. The main greenhouses have a frontage 
of about two hundred feet, the palm house rising some 
seventy feet, and there are six small special houses. The 
botanical museum, lecture room and laboratories are in 
one building, 
The systematic plantations of herbaceous species are exten- 
sive, the rock garden being an especially strong feature. 
The development of arboretum and fruticetum in the newer 
portion of the tract has made good progress. The institution 
is in intimate relationship with the University, nearly all the 
instruction in botany being given at the garden. The re- 
search work has been extensive along taxonomic, morpho- 
logic and physiologic lines. 
8. The Royal Botanic Garden of Dublin, situated at Glas- 
nevin, just without the city, was founded through the influence 
of the Right Honorable and Honorable Dublin Society, in 
1790, was for many years supported by this Society with the 
aid of government grants, and was transferred to the Science 
and Art Department in 1877. It includes about forty acres 
of undulating land, bounded to the north by the small river 
Tolka. There are eight greenhouses, most of them rather old, 
but containing a valuable collection. There is a small botan- 
ical museum and herbarium. The sy 
plantations are irregularly shaped beds, arranged in a some- 
what radial manner. The arboretum and fruticetum occupy 
about one-half of the area. 
g. The Brussels Botanical Garden lies in the heart of the 
city and embraces not more than ten acres of land, of which 
about one-half is given tothe arboretum. The greenhouses are 
large but old. There is a very extensive herbarium and 
library. The systematic beds are arranged as quadrants of 
a circle, separated by concentric and radial paths. Spe- 
cial areas are devoted to ornamental and economic plants. 
Owing to the restricted size of the area available a very dense 
grouping of plants is necessitated. The research work accom- 
plished here has been mainly taxonomic. The Botanical So- 
ciety of Belgium has its headquarters at the garden. 
the large herbarium and library in another.
