under the same roof? Besides, when the fever rages at its worst in the hospital, the women delivered in their homes are not affected more than usual. An epidemic is not limited by walls: cholera spreads over a wide area.

It is said that so many of the women die because they are unmarried and have been seduced. But this cannot explain the difference in the mortality of the two divisions, since exactly the same class of patients are admitted to both clinics. Moreover, nature never feels outraged because the mother does not possess a marriage-ring.

It is argued that the medical students examine the women in a rougher manner than do the midwives, and thus cause injury which results in death. But certainly a uterus enlarged by a fetus can tolerate the most ungentle index finger.

They say the ventilation is wrong, but the same method of allowing air to enter is employed in both divisions.

It is all nonsense to talk about the diet, the warming, the washing. The same caterer supplies food to both divisions; the same washerwomen clean the linen of the first and second clinic.

The women surprised by labor in the streets, who give birth to children on door-steps and under arch-ways, tho the day be cold or the night stormy, are not attacked by puerperal fever. Why, women of the country, gored open and delivered of their seed by the horns of maddened bulls, have a better chance of life than the pregnant female who comes to lie in the First Obstetric Clinic of Vienna's Maternity Hospital.

Thus musing, the distracted Assistant finds he has walked far out to the Central Cemetery, where reposes the illustrious dust of Beethoven and Mozart and Gluck and Schubert. But Semmelweis is not in a mood for melody. The subtle and resistless onset of puerperal fever, the vacant chair by the desolated fireside, the straight road from the marriage-bed to the dead-house, the husband undone and a baby for a salaried wet-nurse, these are the discords which afflict the sensitive Hungarian who has taken the vow of Hippocrates.

He has reached the environs of Vienna. In the distance, seeming to come from the left bank of the Danube, in the direction of the battlefield of Wagram, he hears the note of a church-bell. He starts disagreeably at the sound. He has heard that doleful tone too often of late. At the Clinic, when the end draws near, and the priest bears the last sacrament to her who bids the world farewell, a bell is rung to mark the passing of a soul. And this frequent, solemn tolling jars with strange effect the nerves of the doctor.

He turns homeward: the problem yet unsolved, still in the grip of a hideous malady. Everywhere is endless confusion; only this much proven: they die, they die, they die. Again the bell clangs: it is an exhortation, O Semmelweis! to be clear of vision and find the source of childbed fever, so the mothers of the race may conceive in safety, and breasts ripe for nursing will not shrivel till the love-fruit takes its fill.

In the early spring of 1847,—the same year that Oliver Wendell Holmes became Professor of Anatomy at Harvard - Semmelweis went for a short vacation to Venice, but unlike Byron, he did not lean back in a gondola with voluptuous languor, while a black-eyed Venetian girl opposite read the tales of Boccaccio.

On the twentieth of March he returned to Vienna, and a few hours later was at his post, prepared to resume his duties with renewed ardor. But the first news he heard was the sad fate of Kolletschka, a friend whom he highly esteemed. Kolletschka was Professor of Medical Jurisprudence, and while performing a post-mortem examination in a medico-legal case, was accidentally pricked on the finger by the knife of a pupil. Thru the tiny stab-wound the poison from the scalpel's tip entered, and inflammation ran wild in the Professor's body: lymphangitis, phlebitis, peritonitis, peritonitis, pleuritis, meningitis. Blood-vessel and lymph-channel conveyed the infection to his eyes, and Kolletschka was sightless and lifeless before Semmelweis returned from feeding the pigeons that fly below the golden horses of St Mark.

As Semmelweis listened to the details of the case, to him as to Porphyro on a sweeter occasion, 'a thought came like a fullblown rose, flushing his brow, and in his pained heart made purple riot.' Lymphangitis, phlebitis, peritonitis, pleuritis, meningitis, these were the symptoms observed in women who perished of puerperal fever. Semmelweis saw that Kolletschka and the puerperal women died from an identical cause - from septic infection, from poisoned cadaveric material absorbed by the vascular system. Puerperal fever was not a malady unique in nature—it was simply a form of pyemia!

Now it became clear why the mortality of the first obstetric clinic was so much higher than the second: the instruction of the midwives did not include work on the cadaver; therefore they did not often come into contact with decomposing organic matter. But pathologic anatomy was all the rage in Vienna, and the medical student had an overdose of dissection. From the dead-house they came to the labor-ward, and with hands to which the cadaveric particles still adhered, poison lurking behind every finger-nail, they examined the pregnant, parturient, and puerperal women. And the gaping genitals freshly wounded by travail, the denuded surface of the vagina, the fissures about the fourchette, the lacerations near the mouth of the womb, easily sucked up the noxious virus that spelled disaster and death.

A little later Semmelweis discovered that not only decomposing cadaveric matter, but that putrid matter derived from living organisms, and even the atmosphere when overloaded with foul exhalations, may produce the dreaded septicemia. After this, the students who came to the First Clinic found a new rule: before touching a woman they must disinfect their hands with a solution of chlorinated lime. This was the introduction of antisepsis into obstetrics. Immediately the slaughtering of the mothers was lessened, and soon for the first time in the history of the Vienna Lying-in Hospital - the mortality in the First Division fell below that of the Second Division. A chunk of chloride of lime upsetting a hundred

theories, accomplished this miracle. Now to proclaim the Doctrine to the whole world!

Semmelweis had reason to congratulate himself: the next day the three greatest men in Vienna were his disciples. Skoda referred to his discovery as one of the most important in the domain of medicine. Rokitansky at once accepted his new etiology of puerperal fever. Lest it be deemed strange that a man whose days were spent in the dissecting-room should be so alive to new ideas, we must say that Rokitansky kept sweet and sane by memorizing Kant and marrying a singer. Hebra, who knew so much about itch that we call him the Father of Modern Dermatology, was editor of the Journal of the Medical Society of Vienna, and wrote a couple of articles in which he linked the name of Semmelweis with that of Edward Jenner. In return for the compliment, Semmelweis acted as accoucheur in Frau Hebra's next confinement, and his skilled and sterilized hands delivered the good woman in safety.

But not many were as clear-headed as this triumvirate, and misoneism, that insidious inertia of the mind which makes mankind averse to innovation,- soon asserted itself in clinic, hospital and lecture-room. Semmelweis awoke and found himself famous and hated.

At this period, however, something happened in Europe which caused even Semmelweis to forget puerperal fever. A nobler fever attacked Mother Earth- the fever of 1848. This was the year in which barricades rose like magic to the sound of the singing of the Marseillaise; the year of Mazzini and the Roman Republic; the year of Garibaldi and his redshirts; the year of flying popes and abdicating emperors; the year of overturned thrones and angry peoples; the year when the workingman's pike was aimed at the monarch's scepter; the year of endless courage and divine defiance; the year of young blood and new life.

Knout-cursed Russia did not tug at her chains, but every other nation leaped up in fiery revolt. Of course, Austria was

all turmoil, for Austria, the lengthened shadow of Metternich, was the chief oppressor of western Europe. The university students of Vienna, cursing the prince's cruelty, broke into Metternich's home, and drove the old monster over the continent.

Professors and pupils, physicians and lawyers, formed an Academic Legion. Ferdinand Hebra, tho more accustomed to dermatologic eruptions than to political ones, enrolled as a member. Ludwig Frankl, the Jewish poet-physician, joined the students; he wrote Die Universitat, which twenty composers set to music, while half a million copies went thru Austria and Germany. Ernst Krackowizer, the first person in Vienna on whom the anesthetic properties of chloroform were tried, unsheathed his sword for freedom. And when the reactionary Professor Klein walked thru his clinic, whom should he see arrayed in the uniform of the revolutionary Legion, but his assistant, Dr Ignaz Philipp Semmelweis. could hardly recognize him at first because of the broad hat with the waving plume. And what was it he held in his hand—a scalpel or a sword? Hippocrates was supplanted by Louis Kossuth.

In Berlin the worthiest sons of Esculapius acted in the same way. Rudolph Virchow was deprived of his posts by the Prussian authorities, and another turn of the fickle wheel of fortune might have snuffed out his life. Physicians have not yet discovered the drug that ensures perpetual youth, and few who warmed their hearts in the sacred blaze of 1848, are now alive. Yet we all know one physician who was then in prison for liberty's sake, and still lives and practices his profession, and has recently become the President of the American Medical Association: Ave Magister, Abraham Jacobi!

Magyarland, under the brilliant leadership of Kossuth, was gaining its independence. But the strong Czar poured his armies into Austria, and a hundred thousand armed Russians trampled out Hungary's freedom. The flame of rebellion flickered low, and 1849 was the year of reaction. The barri
