latter in their construction, which consists of a number of 
cells piled one on the other; and in having no terminal 
cavity for the reception of the body of the animal. 
The cells are furnished with one or more small mouths, 
and placed one on another in different directions, some 
forming straight lines, as Nodosaria, and others spiral 
ones, as Rotalia. In others the cells are half the length 
of a whorl, so that each new cell changes the situation of 
the mouth from one to the other end of the shell, as in 
the Miliolce : and in others the cells are divided into nu¬ 
merous longitudinal tubes, as in Alveolina and Fabularia . 
These animals have been generally arranged with the 
Nautili , and some have classed them with the Cephalo - 
podous Mollusca t while others have thought they might be 
formed by animals allied to the Annelides . One author 
has proposed that they should be formed into a class, 
which he proposes to call Rhizopodes ; but it is not im¬ 
probable, when they shall have been more completely 
examined, that they will be found to be allied to the 
Polyzoa; and the body, which has been called their shell, 
may prove to be only a hardened skin, like the cells 
formed by that class of animals.

NORTH GALLERY. 
This Gallery, above the Library on the North side of 
the North Wing, is appropriated to the Oryctognostic 
or Mineralogical Collection, and to that of Palaeontology 
(Secondary Fossils or Organic Remains). The greater 
portion of these Collections, removed from the room here¬ 
tofore called the Long (but now the Eastern Zoological) Gal¬ 
lery, is under re-arrangement. According to the plan laid 
down for their distribution, the Table Cases containing 
the General Collection of Minerals will form two rows 
or series, extending through four rooms, as follows:’— 
In Room I., being the N.E. corner room, the first 
series of Table Cases begins and the second terminates: 
it contains Cases 1 to 6 and 56 to 61. Room II. con¬ 
tains the Cases 7 to 13 and 49 to 55. Room III. will
