sores, wasting of the bones, emancia-
ton; loss of appetite, strength and flesh,
sores in the nose and ears, loss of hair,

ease, suppose themselves cured, but az

er had before, and which they find it
impossible to relieve.

mend trial of his skill The symp-
toms with which you are troubled are
caused by taints in the blood, which

HIGHLY IMPORTANT DISCOV-
cry,

DIR. J. C. YOUNG, who is celebra-
ted for curing all private complaints of
both sexes, has discovered remedy for
the cure of old, long standing cases of
gonorrh@a and elects, which he has tri-
ed in more tLan one hundred cases, sue
cessfully, many Of which had baffled the
skill of eminent physicians for years !;
and in not one single case has it failed,
nor can it ever fail, as the nature of the
remedy is such that it strikes at the
root Of the complaint, and eradicates it
completely in few days. New cases
cured in an incredibly short space of
Columbia gazette. [volume] (Columbia, Tuolumne County, Calif.) 1852-1855, 1854-09-30

cures all the most aggravated cases of
this disease, and mild ones he removes
in from two to five days. The doctor
has for many years, been known as the
most eminent and successful physician
in the United States, and what is more
important to the patient, he always eff
fects speedy and permanent cure.
Travellers, seamen, miners and 9TH
ers, who wished to be cured without
mercury, hindrence from business, or
exposure to friends, should apply to him
as soon as possible, and perfect cure
will be guaranteed in all curable cases.

From the ECHO du Pacihc.
DR. HUNGERFORD.
We wish to call the attention of our
readers to the advertisement Of this gen.
tleman, whose extensive practice and
great success is sufficient to induce all
those afflicted to give him call. The
Doctor is not only a regularly educated
Physician, but he has the principles of
honesty and a heart that can feel for his
fellow beings. He has undoubtedly
more practice than any other Physician
in San Francisco, and it is fast increas-
ing. To those acquainted with the Doc
tor. we say nothing as to his skill and
integrity, as they are we'll known; but
to strangers we do say, call at No. 1851
Dupont street, and you will find that a
friend in need is friend indeed.
From the Southern Medical Journal. y
PROFESSOR HUNGERFORD.
Although opposed to the system Of
advertising, yet we deem it but just to
this gentleman to admit that his system
of treatment in Private Diseases is un-
doubtedly the most approved one now
in use throughout the civilized world.
