them in close connection with the remainder of the tropical 
plants. This has proved a decided advantage, as was antici- 
pated, as it not only greatly facilitates the study of these 
plants, but also simplifies the work of their culture. This 
procedure required the rearrangement of the plants in houses 
nos. 7 and 8, and also necessitated the removal of a number 
of individuals, that room might be made for the additions. 
The larger specimens, which it was desirable to retain, were 
removed to house no. 4, and the number of specimens of 
each remaining species was reduced to two individuals, the 
lowest number permissible to safeguard the collections. 
The duplicate material was either disposed of by exchange, 
or, in the case of common species, destroyed. Even with 
this thinning out the collections in nos. 7 and 8 are too 
crowded, and more room for them will soon be required. 
There are now, therefore, three houses devoted to the tem- 
perate collections, viz.: nos. 12, 13 and 14. The collection 
of plants for study purposes, arranged according to the 
Engler and Prantl sequence of families, which was formerly 
confined to house no. 12, has now been extended to include 
house no. 14; the cryptogams, endogenous plants and the 
exogenous plants up to the Myrtiflorae are in house no. 12; 
the remainder, from and including the Myrtiflorae, have been 
removed to house no. 14, the sequence beginning with the 
east end of the north bench, and terminating at the east end 
of the south bench. House no. 13, as is the case with house 
no. 4 for the tropical plants, is now devoted to such material 
as is too large for proper accommodation on the benches in 
the other houses. From the shape of this house it was not 
possible to follow so rigidly the botanical sequence adopted 
in the study collection, where it is planned to represent as 
many families and genera as possible. The grouping by 
families is adhered to, however, and the families themselves 
are grouped as much as possible in the larger divisions. The 
endogenous plants are located in a portion of the northwest 
and southwest corners, the amaryllis family in the former, 
and the grass, sedge and lily families in the latter. The
