. In the fall of 1909, American army surgeons were experimenting
with a serum at Washington and on Governor's Island with success, but
the first public announcement of an absolutely successful vaccine was
made by Captain Vincent of the French navy on June 20th, 1910, before
the Academie de Medicine in Paris. The final success of the anti-typhoid
serum has been conclusively proved by elaborate tests upon soldiers and
sailors in many nations.

It is difficult for the ordinary individual to appreciate the
significance and importance of a discovery of this character and
magnitude. When one thinks calmly of the thousands and thousands of men
who have lost their lives during wars because of typhoid epidemics, and
of the thousands of others who have returned home practically invalided
for life from the same cause, it is possible to, at least, conceive of
the benefit to the race such a discovery promises. And when we learn
that the discovery is a product of the same principle or method which
gave to the world a cure for smallpox, diphtheria and syphilis, we must
begin to believe that the medical profession is on the path which is
unlimited in its field of promise so far as efficient treatment is
concerned. Yet to-day we have people who do not believe in vaccination
or in anti-diphtheritic serum. We may not live to see the time, but it
is not far distant in the opinion of men qualified to speak with
authority, when every disease will be amenable to the serum therapy, and
when drugs will virtually be discarded by the human race.

"606."--One of the most important discoveries in the history of
medicine was recently given to the world by Dr. Paul Ehrlich.

He called it "606," because it was the 606th experiment he had made with
the same end in view. It was designed with the purpose of curing the
most terrible disease known to man, syphilis. The name of the remedy is
salvarsan. That it will do all that was first claimed for it is still
doubtful, but salvarsan and its improvements, neosalvarsan, etc., are
accepted by the profession as by far the best treatment yet devised for
this dread disease. It points the way for improvement along the same
line to an ultimate specific.

Transplanting the Organs of Dead Men Into Living Men.--To take from a

immersing them in certain fluids thereby keeping them alive
indefinitely, and later transplanting them in the body of a livi
