adoption of these various means, we are enabled to fully meet the
demands of the afflicted, and give every case the most careful
attention.

As many persons, particularly young ladies and gentlemen, having catarrh
or almost any other chronic disease, especially if of the urogenital
organs, are very sensitive and fearful that somebody will know that they
are afflicted and employing medical treatment, precautions are taken
that none who consult us may incur the least risk of exposure. Although
none but the most honorable and trustworthy gentlemen are employed as
assistants, yet as a _guarantee_ of perfect security to our patients,
that every communication, whether made in person or by letter, will be
treated as _sacredly confidential_, each professional associate, clerk,
or assistant, is required to take a solemn oath of secrecy. Great care
is also taken to send all letters and medicines carefully sealed in
plain envelopes and packages, so that no one can even _suspect_ the
contents or by whom they are sent.

ADVANTAGES OF SPECIALTIES.

By thorough organization and a perfect system of subdividing the
practice of medicine and surgery in this institution, every invalid
consulting us is treated by a specialist--one who devotes his undivided
attention to the particular class of diseases to which his or her case
belongs. The advantage of this arrangement must be obvious. Medical
science offers a vast field for investigation, and no physician can,
within the limit of a single life-time, achieve the highest degree of
success in the treatment of _every_ malady incident to humanity. A
distinguished professor in the medical department of one of our
universities, in an address to the graduating class, recently said:
"Some professional men seem to be ashamed unless they have the character
of universal knowledge. He who falls into the error of studying
everything will be certain to know nothing well. Every man must have a
good foundation. He must, in the first place, be a good general
practitioner. But the field has become too large to be cultivated in its
entirety by any individual; hence the advantage of cultivating special
studies in large towns, which admit of the subdivision of professional
pursuits. It is no longer possible to know everything; something must
be wisely left unknown. Indeed, a physician, if he would know anything
