The Work which is now presented to the public is the result
of very extended experience in a class of diseases and affee-
tiut.s, which for some unaccountable reason have been either
altogether overlooked, or treated with apathy, and almost in-
difference, by the t dinary practitioner. To enter into the
details of these affections, to point out their causes, and to
mark the terrific consequences, social, moral, and physical,
which are sure to follow from indulgence, in certain habits,
would be entirely out of place in an advertisement. We have
no hesitation, however, in saying that there is no member of
society, by whom the book will not be found interesting, whe-
ther we consider such person to hold ►he relation of a PA-
RENT, a PRECEPTOR, or a CLERGYMAN.
Messrs. CURTIS and CO. are to be consulted daily at their
residence, No. 7, Frith-street, Soho, from Ten till Three, and
Five till Eight in the Evening; and Country Patients arc re-
quested to be as minnte as possible in the detail of their cases,
—as to the duration of the complaint, trip symptoms, age, ge-
neral habits of living, and occupation in life of the party ; the
communication mns+• be accompanied by the " usual Consulta-
tion Fee of 11.," without which no notice whatever can he
taken of their application ; and in all cases, the most inviolable
secrecy may he relied an.
