whenever they had an Inclination to play their Pranks. Friar Bacon, who was perhaps the greatest Chymist in Europe, used to play so many Tricks, that he was thought by the whole Country, to deal with the Devil; and many Stories of him are now extant, to that Effect. One of the most common Pranks amongst these Gentry was this: They used to get one who could draw well, to take some Phosphorus (which is a Chymical Preparation from Urine) in his Pocket; having thus armed themselves, they perhaps would step into the first Alehouse where they saw a Light, and mix with the Company. He who was in Possession of the Phosphorus would get up and go to the Wall, under some Pretence or other, upon which he would draw what Picture came first into his Head, very likely the Picture of the Devil. Nothing is to be seen by Candle-Light, and it must be dark, before the Marks made by Phosphorus upon a Wall will appear like Fire. After sitting a little while, one of them would either introduce some Discourse about the

Wickedness of the Times, or would tell some Story about Apparitions; in the middle of which another would run against the Candle, as if by Accident, and put it out. As soon as the Candle is out, another of them pretends to have found out this Figure upon the Wall, which will appear like Fire. You may guess the Surprize of the poor Country People, at seeing the Old Gentleman upon the Wall.—They all take to their Heels. In the mean Time, to improve their Ideas, another of the Confederates sets Fire to Brimstone, or some other stinking Combustible, and pops it against all their Noses, as they run out of Doors; and after these two powerful Sensations of seeing and smelling, it would be quite impossible, by any Arguments, to persuade any of the Company, that they had not actually seen the Prince of Darkness. By these and such like Arts, the Roman Catholic Priests so long kept this now well-delivered Country under their Subjection.

Though this Account appears ridiculous enough, the Effect which such Sort of Pranks have upon the weak Minds of Women and Children, are very serious; and the Ideas which are received at this Time of Life, make such an Impression upon some People, that they are unable to get the better of their Apprehensions, even when they grow up.

I know a Person of the first Sense, and a great Scholar, who retains these Stories so strong in his Memory, that he dare as well put his Fingers into the Old Lion's Mouth at the Tower, as go up to a Monument, which stands in a certain Chapel in this University, after it is dark; not that he really believes any Thing would hurt him there; nevertheless he declares he cannot get the better of it. And I make no Doubt, that not only this Gentleman, but Thousands more of his Majesty's good and bold Subjects, are in the same Way.

I look upon our Sailors, to care as little what becomes of themselves, as any Set of People under the Sun; and yet no People are so much terrified at the Thoughts of an Apparition. Their Sea Songs are full of them; they firmly believe their Existence; and honest Jack Tar shall be more frightened at a glimmering of the Moon upon the Tackling of the Ship, than he would be if a Frenchman was to clap a Blunderbuss to his Head.

I was told a Story by an Officer in the Navy, which may not be foreign to the Purpose.

About half a Dozen of the Sailors on board a Man of War, took it into their Heads, that there was a Ghost in the Ship; and being asked by the Captain, what Reason they had to apprehend any such Thing, they told him, that they were sure there was a Ghost, for they smelt him. The Captain at first laughed at them, and called them a Parcel of Lubbers, and

advised them not to entertain any such silly Notions as these, but mind their Work. It passed on very well for a Day or two; but one Night, being in another Ghost-smelling Humour, they all came to the Captain, and told him, that they were quite certain, there was a Ghost, and he was somewhere behind the Small-beer Barrels: The Captain, quite enraged at their Folly, was determined, they should have something to be frightened at in earnest; and so ordered the Boatswain's Mate to give them all a Dozen of Lashes, with a Cat 'o nine Tails; by which means, the Ship was entirely cleared of Ghosts, during the remainder of the Voyage. However, when the Barrels were removed, some Time after, they found a dead Rat, or some such Thing, which was concluded, by the rest of the Crew, to be the Ghost, which had been smelt a little before. Thus we see, that the bravest Men of the Universe, may be terrified, if they give way to their own chimerical Ideas; and that it is only for want of searching into the Causes of the Phœnomena of Nature,
