PUBLIC NOTIFICATION.

MESSRS. SLOAN and CO., Members of
the Royal College of Surgeons, 4, ARGYLL-PLACE,
REGENT-STREET, and 28, IRONNIONGER.LANE,
CHEAPSIDE, may be consulted from Eight o'Clock in the
Morning until Ten at Night, on every variety and stage of
Qyphili6, with that delicacy and secresy they have hitherto ob-
served. The treatment they pursue will not subject any patient
to confinement or hindrance from business. Cases of an ex-
treme nature they eradicate in eight or ten days, or if slight or
recent in two or three, without the indiscriminate use of mer-
cury, .and at a moderate expense. Generative 'lebility,
Gonorrhma, and Strictures of the Urethra, unhappily so preva-
lent, are treated upon those unerring principles which have in-
eared to Messrs.- Sloan and Co. sol:. rge a share of public pa-
tronage for nearly thirty years in London, and which it will be
their future exertion to maintain.
Letters, containing an.enclosure, will be answered by return
and patients, however distant, will be corresponded with until
