*E. a. 310. Chest of a large man, greatly deformed by an
old, anchylosed caries of the spine, which affected most of
the dorsal and lumbar vertebrae. The disease appears to
have been completely arrested long previous to the death of
the individual. The spine is bent to a right angle ; and large
masses of hard bone form one continuous chain along the fore-
part of the bodies of the vertebrae, giving it Support, and
rendering it quite immoveable: towards the lower part, one of
these bony productions forms a considerable exostosis, which
must have interfered with the soft parts in its vicinity. The
particular deformity of the chest, the result of such an
amount of disease, is well shown.
*E. a. 311. A bottle holding a dry preparation, exhibiting
a caries of the bodies of the lumbar vertebrae, with a sac of
a psoas abscess on each side. The abscess of the left side
communicates by a small circular aperture with the disease in
the bones: that on the right, is perfectly smooth inside, and
has no such communication. They are of the same size and
lay in their respective psoas muscles as far as pouparts
ligaments.
*E. a. 312. A wet preparation of caries of the vertebras,
in a person about fourteen aetatis. All the lower dorsal
and first lumbar are diseased. The anterior parts of the
bodies have been exposed, by turning aside the thick cyst of
an abscess which lay over them. They all retain their form,
except that of the last dorsal which is gone, as in some of the
other specimens in the collection. The deformity is inconsiderable.
#E. a. 313. A caries of one of the dorsal vertebrae in an
adult, complicated with an abscess, which, after coursing
behind the left lung, terminates in a fistulous opening in the
back, between two of the ribs, all of which circumstances are
shown in the preparation.
*E. a. 315. A beautiful dissection of a spina bifida in an
infant. The spinal marrow in its whole length, the defect in
lumbar and sacral vertebrae, the interior and exterior appearances
of the sac, together with the origin and description of
the nerves connected with it, are well exhibited.
*E. a. 316. Caries of the central portion of one of the true
ribs: better than two inches of the rib is destroyed; and
yet, nevertheless, the pleura lining it exhibits little mark
of disease. It is, perhaps* slightly opaque ; but is free from
any effusion of lymph, or adhesion to the pleura pulmonalis.
E. a. 320. A finely injected specimen of caries of the new
bone, formed after necrosis of the right tibia, in a male adult.
The two superior thirds of the tibia had been discharged as
Sequestra, and the cavity was filled up with osseous matter.
All was going on favourably, until, during a deranged state of
health* the reparative gave Way to a destructive process, and
the newly formed bone ran into carious ulceration, The
preparation speaks for itself. The tibia, near to the knee-
joint, is eaten nearly through by ulceration; the neighbouring
bone is enlarged and solidified, and the periosteum
thickened and vascular. The patient* after many years of
great suffering, and after the most dangerous stages of the
disease had been passed over safely, was obliged to submit to
amputation.—Prof. Todd.
*E. a. 321. This preparation—a caries of the new bone of
a necrosis of the tibia—is the counterpart of the preceding :
the head of the tibia is loosened from the shaft* and the intermediate
space is occupied by a ragged, soft, vascular substance.
The fibula appears healthy,
*E. a. 322. A preparation showing the effects of whitlow of
a finger, when advanced so far as to have produced disease of
the bones. The second and third phalanges are those implicated
; they are nearly destroyed by a caries of their anterior
surface, and by disease of the intermediate joint. The finger
is much shortened as compared with that of the opposite
