tion of his urethra, went very far to sustain
this conclusion. On August 23d I removed the stone without difficulty
by the lateral operation through the perineum. The lobe of the prostate
was enlarged, which seemed to favor the extent of the incision beyond
what would otherwise have been safe. The perineum was deep and the
tuberosities of the ischii unnaturally approximated. The calculus of
the mixed ammoniaco-magnesian variety was egg-shaped, and weighed 19
drams. The arrow-point was completely covered and imbedded near the
center of the stone. It was of iron, and had been originally about 2
1/2 inches long, by 7/8 inch at its widest part, somewhat reduced at
the point and edges by oxidation. The removal of the stone was
facilitated by the use of two pairs of forceps,--one with broad blades,
by which I succeeded in bringing the small end of the stone to the
opening in the prostate, while the other, long and narrow, seized and
held it until the former was withdrawn. In this way the forceps did not
occupy a part of the opening while the large end of the stone was
passing through it. The capacity of the bladder was reduced, and its
inner walls were in a state of chronic inflammation. The patient
quickly recovered from the effects of the chloroform and felt great
relief, both in body and mind, after the operation, and up to the
eighth day did not present a single unfavorable symptom. The urine
began to pass by the natural channel by the third day, and continued
more or less until, on the seventh day, it had nearly ceased to flow at
the wound. But the restless spirit of the patient's friends could no
longer be restrained. Open hostility with the whites was expected to
begin at every moment, and they insisted on his removal. He needed
purgative medicine on the eighth day, which they refused to allow him
to take. They assumed entire charge of the case, and the following day
started with him to their camps 60 miles away. Nineteen days after he
is reported to have died; but his immediate relatives have since
assured me that his wound was well and that no trouble arose from it.
They described his symptoms as those of bilious remittent fever, a
severe epidemic of which was prevailing at the time, and from which
several white men and many Indians died in that vicinity." The calculus
was deposited in the Army Medical Museum at Washington, and is
represented in the accompanying photograph, showing a cross-section of
the calculus wi
