ns, and
after traversing the substance of the right corpus cavernosum d, for its
whole length, re-enters the neck of the bladder through the body of the
prostate.

Fig. 8, Plate 59.--A bougie, c c, appears tearing and passing beneath
the lining membrane, d d, of the prostatic urethra. It is remarked that
the origin of a false passage is in general anterior to the stricture.
It may, however, occur at any part of the canal in which no stricture
exists, if the hand that impels the instrument be not guided by a true
knowledge of the form of the urethra; and perhaps the accident happening
from this cause is the more general rule of the two.

Fig. 9, Plate 59.--Two strictures are represented here, the one, e,
close to the bulb d, the other, f, an inch anterior to this part. In the
prostate, a b, are seen irregularly shaped abscess pits, communicating
with each other, and projecting upwards the floor of this body to such a
degree, that the prostatic canal appears nearly obliterated.

Fig. 10, Plate 59.--Two bougies, d e, are seen to enter the upper wall
of the urethra, c, anterior to the prostate, a b. This accident happens
when the handle of a rigid instrument is depressed too soon, with the
object of raising its point over the enlarged third lobe of the
prostate.

Fig. 11, Plate 59.--Two instruments appear transfixing the prostate, of
which body the three lobes, a, b, c, are much enlarged. The instrument d
perforates the third lobe, a; while the instrument e penetrates the
right lobe, c, and the third lobe, a. This accident occurs when
instruments not possessing the proper prostatic bend are forcibly pushed
forwards against the resistance at the neck of the bladder.

Fig. 12, Plate 59.--In this case an instrument, d d, after passing
beneath part of the lining membrane, e e, anterior to the bulb,
penetrates b, the right lobe of the prostate. A second instrument, c c,
penetrates the left lobe. A third smaller instrument, f f, is seen to
pass out of the urethra anterior to the prostate, and after transfixing
the right vesicula seminalis external to the neck of the bladder, enters
this viscus at a point behind the prostate. The resistance which the two
larger instruments met with in penetrating the prostate, made
