f the case than if present in person, and subject to
the most thorough questioning and "cross-examination." The timid lady
and nervous young man write just as they feel and one reason why we have
had such success in treating intricate and delicate diseases, is because
we have obtained such true and natural statements of the cases from
these letters, many of which are perfect pen pictures of disease. As
bank tellers and cashiers, who daily handle large quantities of
currency, can unmistakably detect spurious money by a glance at the
engraving or touch of the paper, so the experienced physician, by his
great familiarity with disease, becomes equally skilled in detecting the
nature and extent of a chronic malady, from a written description of its
symptoms. To aid the patient in giving a clear and intelligible history
of his case we send, when requested, a very complete question blank.

EXAMINATION OF THE URINE.

A careful, microscopical examination and chemical analysis of the urine
is a valuable aid in determining the nature of these diseases of the
nervous system. This important fact is not overlooked at the Invalids'
Hotel and Surgical Institute, where experienced chemists are employed to
make such examinations and report the result to the attending
physicians. Persons consulting us and desiring to avail themselves of
the advantages afforded by these examinations, can send a sample of
their urine by express. The bottle should be thoroughly cleansed and
should contain from two to four ounces of that first passed after
arising in the morning. It should be carefully packed in saw-dust or
paper and inclosed in a light wooden box. All express charges must be
prepaid through and a complete history of the case, including the age
and sex of the patient, should accompany every package, or it will
receive no attention. This saves valuable time by directing the
examination into the channels indicated and thus avoiding a lengthy
series of experiments. As we are daily receiving numerous bottles of
urine, every sample, to prevent confusion, should be labeled with the
patient's name. By the postal regulations, all liquids are excluded from
the mails, unless packed in accordance with our printed directions,
which will be sent free on request being received for them.

WE AIM TO CURE,

not merely to palliate as is so often done by practitioners in dealing
with these distressing maladies. We do not prescribe coca mixtures,
whiskey
