PROCEEDINGS OF SOCIETIES. 65 
Mosses, of which about two hundred and forty species have 
been planted in my bryarium, which is a glass case about 
4. feet 6 inches long, 22 inches from back to front, and 26 
inches in height. It is fitted with shelves, and has two doors, 
one of which is generally left only partially closed. The 
plants are in separate pots, and are never removed from the 
case, but are kept in the shade and frequently watered with 
a syringe. Care is taken to procure suitable kinds of soil ; 
but in most instances the soil is sparingly used, the pots being 
more than half filled with drainage. 
ANDREACEH.—A. rupestris flourished and fruited till the 
second season. If removed with a portion of the rock at- 
tached, it might last much longer. 
SpHaGNacez.—The pots were set in trays of water, and 
no soil was put into them. Six species, five of them in fruit, 
were planted, and did well for the first year. SS. acutiflorum 
alone fruited the second year. They are now almost extinct. 
Puascrea#.—From a fine patch of P. nitidum only one or 
two plants came up the second year. 
WetlssirE&.—Seem permanent. W. controversa fruits pro- 
fusely about a month before its usual time. 
Dicranrx.—Stylostegium cespititium from Ben Lawers 
soon perished. Dicranum polycarpum and D. virens from the 
same locality, flourish ; the former fruits vigorously. Eight 
other species, some of them Alpine, seem permanently esta- 
blished. Leucobryum glaucum does not alter in the least. 
CampyLorpopE&.—C. longipilus, from Scotland, thrives ; 
and the common species bears fruit. 
Porrizx.—P. Heimii dies rapidly. P. truncata fruits. 
TricHostomMEz.—T7ri. tophaceum and homomallum disap- 
pear. The Tortule mostly do well, but the case contains no 
Alpine species. 7. ruralis overgrows itself and dies. 
Encatyetex.—E. vulgaris fruited and disappeared. £. 
ciliata remains, but is barren. Two Alpine species from Ben 
Lawers are unhealthy. 
Hepwicirz.—H. ciliata remains, but wants attention. 
GRIMMIEH.—G. pulvinata is a charming little plant for 
cultivation, but must be kept rather dry. Several others do 
fairly. All the Racomitria, except two, flourish and are very 
ornamental. 
OrrHotricHe&.—Tied upon small blocks of wood, and 
suspended, they live, and some of them bear fruit, but do 
not appear thoroughly healthy. Zygodon Lapponicus and 
Z. Mougeotiu are on the wane. Tetraphis pellucida holds its 
own well, but does not fruit. 
PotyrRicHE®.—Pogonatum nanum is gone. P. aloides and
