lways present just the same picture, or set of symptoms, that you
should be able to so rapidly and correctly tell his purely subjective
sensations?"

"Not by any means, Professor. A scientific prescription, like a stool,
must have at least three legs to stand upon. You will remember that the
Count had already told me that moving about, especially at night,
mitigated his pains; that he contracted his ailment from getting wet;
and I noticed that he favored the left leg in walking. These were the
three legs for my stool, or prescription. I felt positive that the
remedy indicated was Rhus Toxicodendron. So I merely mentioned the
leading characteristics of that drug, and I was not mistaken. You see,
then, that I did nothing marvelous nor supernatural. Now, any one of
many other drugs might have been indicated if the symptoms had been
different from what they were. The symptoms of the disease must always
be the same as those that the indicated drug is capable of producing in
crude doses. Rhus tox. will cure the Count because, in every case of
poisoning by that drug, there will be produced the symptoms found in his
case. Like cures like. This is a universal law of God. I feel quite sure
that the Count will experience great benefit from the one dose I have
given him."

"I shall watch this case with the greatest interest," said the
Professor. "You will make a convert of me to your system if you perform
a cure of so obstinate and painful a disease with an infinitesimal dose
of medicine."

"All right, my dear sir. I always feel confident of a cure when the
symptoms are clear cut as in this instance."

A general conversation was now entered into for a few moments, when
servants entered and signaled them to follow, and each was conducted to
a comfortable apartment. They shortly after assembled again in the
drawing-room and awaited the announcement of dinner. Fred opened the
piano, and he and the ladies sang a trio. They were glad when a servant
appeared and signaled them to follow him to the dining-room. The Count
was the only Russian present who could speak English. So he watched
carefully and interpreted the wants of his guests to the servants, and
but very little trouble was experienced. They found the cooking very
palatable, and their mode of living aboard Silver Cloud in the frosty
atmosphere of the Arctic region had sharpened their appetites
enormously.

The Count talked with them about their journey, and was much intere
