is as big as the largest sized melon, occupied a great part of
the cavity. On the abdomen being opened, the tumor fell
out, so that the exact point of its origin could not be determined
by the cook. The tumor is extremely heavy, for its
size; and its surface, though polished, is rough and nodulated.
In the section, it is shown to consist of a dense, fibrous structure,
thickly studded with small, cartilaginous granules, which,
when first cut through, were white and shining, but have
since been altered in color by the maceration. The bird had
been fed about stables; and nothing particular was ever remarked
about it, during lifetime.—Dr. Houston.
D. f. 517. A cut of a gurnet, showing a tumor under the
integuments covering its side. The tumor is encysted, and
holds within, a multitude of small, fatty, granular bodies, like
the ova of a fish, as to shape, and closely adherent to each
other. The fish appears, otherwise, in good condition.—Professor
Jacob.
ORGANS OF LOCOMOTION.
E. a. 1. Section of the tibia of a child showing the effects
of acute periostitis on the periosteum and bone. Case,—a little
girl, getat 7. Deep seated swelling of the leg, with great pain,
sleeplessness and fever were the first symptoms. By an incision
purulent matter was let out. In a week after, she was
attacked with pericarditis, and died on the third week from
the commencement of the illness. The periosteum, as here
shown, was thickened and in great part detached from the
shaft of the tibia : where adhesions remained, the slightest
force destroyed them. The surface of the bone was of a dead
white colour, but the pink shade of the deeper vessels was discernible,
especially near the extremities. The medullary membrane
was highly vascular and exhibited in some places slight
effusions of lymph. No particles of new bone could be detected
in the thickened periosteum. The preparation has lost
many of the more striking characters observable in the recent
state. The surface of the heart was slightly furred with
lymph, and the pericardium distended with a thin, straw-
colored fluid.—J. W. Cusack, Esq.
E. a. 2. Acute periostitis accompanied by synovitis, in a
boy, aged nine years.
The child received a trifling injury on the shin from an iron
bar : in three days, periostitis set in. Gn the 26th day, am
