Lister, to which a Guide has been written by Mr. Lister.* A 
large chalk-like mass of Diatomaceous earth containing twelve 
billion diatoms is placed in a case by itself near the entrance 
to the gallery. The table-case in the first bay on the left 
contains an exhibition of Insectivorous plants, illustrated with 
models and drawings representing their structure. 
At the end of the gallery the larger specimens of Palms are 
set up against the screen dividing the gallery from the her- 
barium ; and the Cycads, Tree-ferns, etc., are placed in the bays 
next the appropriate wall-cases. Suspended from the roof is 
a fine specimen of the " Wabo " Bamboo (Dendrocalamus 
Irandisi) from Burma, 81 feet long. 
A collection of British Plants is exhibited in glazed frames British 
fastened by hinges to uprights, and placed in the corners of the 
gallery. The classification is that used by Bentham in his 
' Handbook of the British Flora,' and his descriptions are 
attached as labels to each plant. Three series of frames contain 
specimens of all the British Vascular Plants. The fourth frame 
is occupied with a complete series of the Mosses, and forms the 
beginning of the exhibition of Cellular Plants. The series is 
continued in the frames on the other side of the gallery con- 
taining the lower Funguses and drawings of the larger 
lunguses by Mr. W. G. Smith. These plants could not be 
dried so as to give a fair idea of their form ; coloured drawings 
have therefore been employed for this part of the series. 
The portion devoted to the use of the scientific student con- Herbarium, 
sists mainly of the great Herbarium of Vascular Plants. This 
is a collection of plants, fastened on single sheets of folio 
paper, representing, so far as it has been possible to obtain 
them, first, every species of plant living on the earth, and 
then the distribution of each species on the surface of the 
earth. The various species are collected under their respec- 
tive genera, and these are arranged in their natural orders ; 
the whole being systematically classified, beginning with the 
Ranunculacece, and going down to the Vascular Cryptogams. 
The Herbarium of Cellular Plants (Mosses, Liverworts, Algae, 
Lichens, and Funguses) is in a separate room entering from the 
head of the staircase in the hall.
