The experiment could not possibly fail. The Turks, who are people of good sense, soon adopted this custom, insomuch that at this time there is not a bassa in Constantinople but communicates the small-pox to his children of both sexes immediately upon their being weaned.

Some pretend that the Circassians borrowed this custom anciently from the Arabians; but we shall leave the clearing up of this point of history to some learned Benedictine, who will not fail to compile a great many folios on this subject, with the several proofs or authorities. All I have to say upon it is that, in the beginning of the reign of King George I., the Lady Wortley Montague, a woman of as fine a genius, and endued with as great a strength of mind, as any of her sex in the British Kingdoms, being with her husband, who was ambassador at the Porte, made no scruple to communicate the small-pox to an infant of which she was delivered in Constantinople.

The chaplain represented to his lady, but to no purpose, that this was an un-Christian operation, and therefore that it could succeed with none but infidels. However, it had the most happy effect upon the son of the Lady Wortley Montague, who, at her return to England, communicated the experiment to the Princess of Wales, now Queen of England. It must be confessed that this princess, abstracted from her crown and titles, was born to encourage the whole circle of arts, and to do good to mankind. She appears as an amiable philosopher on the throne, having never let slip one opportunity of improving the great talents she received from Nature, nor of exerting her beneficence. It is she who, being informed that a daughter of Milton was living, but in miserable circumstances, immediately sent her a considerable present. It is she who protects the learned Father Courayer. It is she who condescended to attempt a reconciliation between Dr. Clark and Mr. Leibnitz. The moment this princess heard of inoculation, she caused an experiment of it to be made on four criminals sentenced to die, and by that means preserved their lives doubly; for she not only saved them from the gallows, but by means of this artificial small-pox prevented their ever having that distemper in a natural way, with which they would very probably

have been attacked one time or other, and might have died of in a more advanced age.

The princess being assured of the usefulness of this operation, caused her own children to be inoculated. A great part of the kingdom followed her example, and since that time ten thousand children, at least, of persons of condition owe in this manner their lives to her Majesty and to the Lady Wortley Montague; and as many of the fair sex are obliged to them for their beauty.

Upon a general calculation, threescore persons in every hundred have the small-pox. Of these threescore, twenty die of it in the most favourable season of life, and as many more wear the disagreeable remains of it in their faces so long as they live. Thus, a fifth part of mankind either die or are disfigured by this distemper. But it does not prove fatal to so much as one among those who are inoculated in Turkey or in England, unless the patient be infirm, or would have died had not the experiment been made upon him. Besides, no one is disfigured, no one has the small-pox a second time, if the inoculation was perfect. It is therefore certain, that had the lady of some French ambassador brought this secret from Constantinople to Paris, the nation would have been for ever obliged to her. Then the Duke de Villequier, father to the Duke d'Aumont, who enjoys the most vigorous constitution, and is the healthiest man in France, would not have been cut off in the flower of his age.

The Prince of Soubise, happy in the finest flush of health, would not have been snatched away at five-and-twenty, nor the Dauphin, grandfather to Louis XV., have been laid in his grave in his fiftieth year. Twenty thousand persons whom the small-pox swept away at Paris in 1723 would have been alive at this time. But are not the French fond of life, and is beauty so inconsiderable an advantage as to be disregarded by the ladies? It must be confessed that we are an odd kind of people. Perhaps our nation will imitate ten years hence this practice of the English, if the clergy and the physicians will but give them leave to do it; or possibly our countrymen may introduce inoculation three months hence in France out of mere whim, in case the English should discontinue it through fickleness.

I am informed that the Chinese have practised inoculation these hundred years, a circumstance that argues very much in its favour, since they are thought to be the wisest and best governed people in the world. The Chinese, indeed, do not communicate this distemper by inoculation, but at the nose, in the same manner as we take snuff. This is a more agreeable way, but then it produces the like effects; and proves at the same time that had inoculation been practised in France it would have saved the lives of thousands.

LETTER XII

ON THE LORD BACON

Not long since the trite and frivolous question following was debated in a very polite and learned company, viz., Who was the greatest man, Cæsar, Alexander, Tamerlane, Cromwell, &c.?

Somebody answered that Sir Isaac Newton excelled them all. The gentleman's assertion was very just; for if true greatness consists in having received from heaven a mighty genius, and in having employed it to enlighten our own mind and that of others, a man like Sir Isaac Newton, whose equal is hardly found in a thousand years, is the truly great man. And those politicians and conquerors (and all ages produce some) were generally so many illustrious wicked men. That man claims our respect who commands over the minds of the rest of the world by the force of truth, not those who enslave their fellow-creatures: he who is acquainted with the universe, not they who deface it.

Since, therefore, you desire me to give you an account of the famous personages whom England has given birth to, I shall begin with Lord Bacon, Mr. Locke, Sir Isaac Newton, &c. Afterwards the warriors and Ministers of State shall come in their order.

I must begin with the celebrated Viscount Verulam, known in Europe by the name of Bacon, which was that of his family. His father had been Lord Keeper, and himself was a great many years Lord Chancellor under King James I. Nevertheless, amidst the intrigues of a Court, and the affairs

of his exalted employment, which alone were enough to engross his whole time, he yet found so much leisure for study as to make himself a great philosopher, a good historian, and an elegant writer; and a still more surprising circumstance is that he lived in an age in which the art of writing justly and elegantly was little known, much less true philosophy. Lord Bacon, as is the fate of man, was more esteemed after his death than in his lifetime. His enemies were in the British Court, and his admirers were foreigners.

When the Marquis d'Effiat attended in England upon the Princess Henrietta Maria, daughter to Henry IV., whom King Charles I. had married, that Minister went and visited the Lord Bacon, who, being at that time sick in his bed, received him with the curtains shut close. "You resemble the angels," said the Marquis to him; "we hear those beings spoken of perpetually, and we believe them superior to men, but are never allowed the consolation to see them."

You know that this great man was accused of a crime very unbecoming a philosopher: I mean bribery and extortion. You know that he was sentenced by the House of Lords to pay a fine of about four hundred thousand French livres, to lose his peerage and his dignity of Chancellor; but in the present age the English revere his memory to such a degree, that they will scarce allow him to have been guilty. In case you should ask what are my thoughts on this head, I shall answer you in the words which I heard the Lord Bolingbroke use on another occasion. Several gentlemen were speaking, in his company, of the avarice with which the late Duke of Marlborough had been charged, some examples whereof being given, the Lord Bolingbroke was appealed to (who, having been in the opposite party, might perhaps, without the imputation of indecency, have been allowed to clear up that matter): "He was so great a man," replied his lordship, "that I have forgot his vices."

I shall therefore confine myself to those things which so justly gained Lord Bacon the esteem of all Europe.

The most singular and the best of all his pieces is that which, at this time, is the most useless and the least read, I mean his Novum Scientiarum Organum. This is the scaffold with which the new philosophy was raised; and when the

edifice was built, part of it at least, the scaffold was no longer of service.

The Lord Bacon was not yet acquainted with Nature, but then he knew, and pointed out, the several paths that lead to it. He had despised in his younger years the thing called philosophy in the Universities, and did all that lay in his power to prevent those societies of men instituted to improve human reason from depraving it by their quiddities, their horrors of the vacuum, their substantial forms, and all those impertinent terms which not only ignorance had rendered venerable, but which had been made sacred by their being ridiculously blended with religion.

He is the father of experimental philosophy. It must, indeed, be confessed that very surprising secrets had been found out before his time-the sea-compass, printing, engraving on copper plates, oil-painting, looking-glasses; the art of restoring, in some measure, old men to their sight by spectacles; gunpowder, &c., had been discovered. A new world has been sought for, found, and conquered. Would not one suppose that these sublime discoveries had been made by the greatest philosophers, and in ages much more enlightened than the present? But it was far otherwise; all these great changes happened in the most stupid and barbarous times. Chance only gave birth to most of those inventions; and it is very probable that what is called chance contributed very much to the discovery of America; at least, it has been always thought that Christopher Columbus undertook his voyage merely on the relation of a captain of a ship which a storm had driven as far westward as the Caribbean Islands. Be this as it will, men had sailed round the world, and could destroy cities by an artificial thunder more dreadful than the real one; but, then, they were not acquainted with the circulation of the blood, the weight of the air, the laws of motion, light, the number of our planets, &c. And a man who maintained a thesis on Aristotle's "Categories," on the universals a parte rei, or such-like nonsense, was looked upon as a prodigy.

The most astonishing, the most useful inventions, are not those which reflect the greatest honour on the human mind. It is to a mechanical instinct, which is found in
