In the trial of some ladies, the taper faded gradually, grew more and more dim, and required several minutes from its first decay, to be quite extinguished. By this it denoted a reluctant and tenacious sacrifice of virtue; in going out suddenly it signified a speedy resolution. A lady came to trial with great alacrity, and seeming quite convinced of her own innocence, but as soon as she was within the knowledge of the taper its light began to waste away. The husband was in despair, while the wife protested vehemently against the extinction, which she called a vile slander; but the taper, after being gradually almost reduced to darkness, suddenly recovered itself into a blaze.

"What!" exclaimed the husband, "has the taper been convinced by my wife's declaration, and recalled its verdict!"

"No," I answered, "it had no intention of going out; but from its approach to darkness, you are to conclude that your wife's virtue has been brought to the same extremity, the taper having been almost extinguished, she must have been almost frail. In every instance the taper follows accurately the example of the lady." The wife was so overcome by the unforeseen exposure of the fault, which she had not quite committed, that by shame and silence she confessed herself to have been nearly faithless. She was conducted to the mirror, into which the husband looking anxiously for the tempter, that he might provide against a return of the danger, saw one of his dearest friends, according to the plan of human affairs. In the case of another wife, the taper gave the same verdict of an approach to error, and when she was brought before the mirror it presented a singular spectacle. The form of a certain young man appeared in it for an instant and vanished, and it was followed by twenty others in succession, only a glimpse being given of each. Being desired to interpret this, I informed the husband, that the fault of his wife had been only thought of, and no choice had been made of an associate; but in her imagination all these young men had been competitors for the office.

It often happened that when a lady was presented to the taper it would decay and revive many times, and some appeared to have been constantly preparing for frailty, yet still without attainment. When the fading of the taper was gradual, its restoration was always by a sudden effort. In several cases, after growing dim, and blazing forth again many times, it went out at last, showing that much endeavour and resolution had been wasted. In the decays of light the flame was more or less reduced in proportion as the danger had been urgent. Sometimes when the alteration was not very palpable there was a dispute about it, the wife urging the husband not to see any diminution of the light.

The fame of these discoveries being spread through the city, every married man was seized with a desire of being set at rest, and those wives who refused the experiment fell under a reproach little less than conviction. For many days the taper continued its information, to the great disturbance of numberless families.

I next undertook to try the fidelity of friends, and fixed a day for exposing pretended kindness. The first who came to this examination were two men celebrated for inviolable friendship to each other. The one owed his life to the courage of the other at sea, and had since, at the risk of his own ruin, preserved the fortune of his friend, in danger of bankruptcy. They had been friends so long and so securely as to want no confirmation, but had been provoked to this trial by the sneers of a satirist, who had written an ingenious treatise to prove that friendship has no real being, and in truth is nothing more than a few letters of the alphabet joined together. This doctrine he enforced also in conversation, and attacking these two supposed friends, he had entreated them to undergo the trial which I had announced, and so confirm the discoveries of his book; upon which they had undertaken, by complying with his desire, to show the fallacy of his tenets. He accompanied them to the experiment for triumph and derision.

I told these inquirers that I could subject their friendship to two kinds of scrutiny, one of which taught a man the secret wishes of his friend concerning him, and the other betrayed what he had said of him when absent. The malicious author advised them to choose this last trial, and strengthen their friendship by their mutual praises out of hearing. To procure this intercourse, I drew back a small sliding door in the wall, and showed the mouth of a funnel. I then desired one of these friends to listen, informing him that from this funnel would issue all that the other had said of him in conversation during the previous month. All were silent and attentive, and very soon a voice was heard in the funnel, which the chief listener recognised as his friend's. The voice first said something moderately in praise of his disposition, and then proceeded to his faults, which it confessed with great sincerity, explaining certain bad propensities, which he had fancied unknown to all the world except himself, and to himself even he had acknowledged them only in moments of uncommon frankness. His countenance betrayed his resentment at his friend's knowledge of these things, but he appeared to be still more mortified when the voice, with much wit, ridiculed his peculiarities of manner and gesture. It seemed that he never could talk earnestly without the cooperation of all his limbs, and embroiling his arms, legs, and body in the discourse. These unnecessary efforts were now represented by his friend so as much to amuse the hearers, whose laughter was preserved in the funnel, and heard at suitable times. While he listened, his guilty friend stood confounded to hear his past remarks coming out of the wall, and had not confidence to disown them. The author was the first who made any observation on the revived detraction. He offered to comfort and appease the injured man. "I fear," he said, "you are discomposed by what you hear; but you should remember that your friend did not mean to vex you, for when he said all this he did not expect it to be kept in a funnel, and let out in your hearing: had he had the least suspicion of such a contrivance, undoubtedly he would have been more circumspect. Pray consider, also, that he has great sagacity, and excels in discerning the characters of men, and that all persons love to exercise any faculty which they have in perfection. Your friend could not avoid observing these particulars; for you cannot expect that a man who has sagacity shall not use it."

"I think," said the injured friend, "if it was necessary for the exercise of what you call his sagacity that he should observe these things he might have kept them secret."

"But then," said the other, "he has a great deal of wit, and to debar him from your failings, which he knows so accurately, and can, therefore, excel with, would be to require too great a sacrifice from his friendship."

The victim would not allow that an urgent want of being witty was a sufficient reason for making a friend ridiculous, but left the house abruptly, and his friend was too much abashed to pursue him with any defence. A reconciliation was afterwards attempted, but in vain.
