The Mascot Moth

On Aug. 7, 1905, magician David Devant premiered an effect that had occurred to him in a dream: A woman appears to vanish instantaneously from a bare stage.

Devant left behind a description of only 310 words explaining how he’d accomplished the illusion. He called it “the best I have ever done.” The lady descends into the floor, leaving behind the dress, supported by a tube covered with black velvet. The dress is pumped full of oil fog, and at the critical instant it’s whisked down through the tube, leaving (apparently) nothing but smoke hanging in the air.

The brief, blurry advertisement above, for Doug Henning’s 1983 Broadway musical Merlin, appears to be the only video online of this illusion. That’s a shame; it would be wonderful to see it more clearly. Devant’s partner John Nevil Maskelyne called it the “trickiest trick he had ever seen.”

Sublime, Ridiculous

https://commons.wikimedia.org/wiki/File:Edward_Lear_1866.jpg

In 1859, Edward Lear wrote a letter to Lord Carlingford entirely in hexameters:

Washing my rosecoloured flesh and brushing my beard with a hairbrush, —
— Breakfast of tea, bread, and butter, at nine o’clock in the morning,
Sending my carpet-bag onward I reached the Twickenham station,
(Thanks to the civil domestics of good Lady Wald’grave’s establishment,)
Just as the big buzzing brown booming bottlegreen bumblebizz boiler
Stood on the point of departing for Richmond and England’s metropolis.

I say — (and if ever I said anything to the contrary I hereby retract it) —
I say — I took away altogether unconsciously your borrowed white fillagree handkerchief;
After the lapse of a week I will surely return it,
And then you may either devour it, or keep it, or burn it,–
Just as you please. But remember, I have not forgotten,
After the 26th day of the month of the present July,
That is the time I am booked for a visit to Nuneham.

Certain ideas have arisen and flourished within me,
As to a possible visit to Ireland, — but nobody
Comes to a positive certainty all in a hurry:
If you are free and in London, next week shall we dine at the Blue Posts?

Both Mrs. Clive and her husband have written most kindly
Saying the picture delights them (the Dead Sea) extremely.
Bother all painting! I wish I’d 200 per annum!
Wouldn’t I sell all my colours and brushes and damnable messes!
Over the world I should rove, North, South, East and West, I would
Marrying a black girl at last, and slowly preparing to walk into Paradise!

A week or a month hence, I will find time to make a queer Alphabet,
All with the letters beversed and be-aided with pictures,
Which I shall give — (but don’t tell him just yet) to Charles Braham’s little one.

Just only look in the ‘Times’ of to-day for accounts of the ‘Lebanon!’
Now I must stop this jaw, and write myself quite simultaneous,
Yours with a lot of affection — the Globular foolish Topographer.

E.L.

Apparently he’d been reading Arthur Hugh Clough’s epistolary verse-novel Amours de Voyage. “The metre is the same,” noted Lady Strachey, editor of his letters, “and the imitation of the style is clever.”

In 1943 an isolated sledge patrol came upon a secret German weather station in northeastern Greenland. The discovery set off a series of dramatic incidents that unfolded across 400 miles of desolate coast. In this week’s episode of the Futility Closet podcast we’ll follow this arctic struggle, an often overlooked drama of World War II.

We’ll also catch some speeders and puzzle over a disastrous remedy.

A Late Carroll Game

Two years before he died, Lewis Carroll came up with a remarkable number-guessing game in which he’d send a volunteer through a long series of arithmetic manipulations, even allowing her to make some private decisions as to how to proceed. Along the way Carroll asked only three questions:

“Is the result odd or even?”

“Is the result odd or even?”

“How often does it go?”

And yet he would always be able to find the original number quickly. Here’s the procedure:

Think of a number (a positive integer).

Multiply by 3.

  • If the result is odd, then add either 5 or 9 (whichever you like), then divide by 2, then add 1.
  • If the result is even, then subtract either 2 or 6 (whichever you like), then divide by 2, then add 29 or 33 or 37 (whichever you like).

Multiply by 3.

  • If the result is odd, then add either 5 or 9 (whichever you like), then divide by 2, then add 1.
  • If the result is even, then subtract either 2 or 6 (whichever you like), then divide by 2, then add 29 or 33 or 37 (whichever you like).

Add 19 to original number you chose and append any digit, 0-9, to this number.

Add the previous result.

Divide by 7 and drop any remainder.

Divide by 7 again and drop any remainder, and tell me what result you get. (“How often does it go?”)

Here’s how to derive the number that was chosen originally:

Multiply the final answer by 4 and subtract 15. If the first answer was “even,” subtract 3 more, and if the second answer was “even,” subtract 2 more.

(Note: Carroll’s version contained an unfortunate flaw; the improvement given here was devised by Richard F. McCoart and includes a faster way to get the answer. See the article cited below. Carroll’s original appears in Morton N. Cohen’s Lewis Carroll, A Biography, 1995. Note too that the two “parity checks” above are identical, so the whole setup is easy to memorize and less bewilderingly complex than it’s intended to appear.)

Impression

https://archive.org/stream/diseasesofnervo00jell/diseasesofnervo00jell#page/n118/mode/1up

This is remarkable — in 2014 ophthalmological neurologist Frederick Lepore showed this image to 100 migraine patients who experience a visual aura. (Click to enlarge.) 48 recognized it instantly.

“People are astonished,” Lepore told National Geographic. “They say, ‘Where did you get that?'”

He got it from English physician Hubert Airy, who had drawn his own aura in 1870, before the phenomenon was even understood.

“Which?”

Submitted by Joseph Hall for Life magazine’s 1915 short story contest:

They were two women, one young, radiant, the other gently, beautifully old.

‘But, Auntie, it’s such fun.’

The older rose.

‘Wait.’

In a moment she had returned. Two faded yellow letters lay upon the young girl’s lap.

‘Read them.’

Wonderingly the girl obeyed. The first read:

Dearest:

I leave you to John. It is plain you care for him. I love you. Just now it seems that life without you is impossible. But I can no longer doubt. If you cared, there would be no doubt. John is my friend. I would rather see you his than any other’s, since you cannot be mine. God bless you.

Will.

The other:

Beloved:

I am leaving you to the better man. For me there can never be another love. But it is best — it is the right thing — and I am, yes, I am glad that it is Will you love instead of me. You cannot be anything but happy with him. With me — but that is a dream I must learn to forget.

As ever and ever,

John.

Whole Story

breakaway table

Shopping at a mall one afternoon, Dave Morice and his son Danny came across a set of poseable wrestling action figures. One accessory was a breakaway table that came in two jagged halves. The store had a policy that allowed customers to return a broken toy for one that wasn’t broken.

Morice said, “Now here’s a problem. The table comes broken in two. If it wasn’t broken, then it would be broken. In either case, it’s broken.”

Danny said, “Yeah! That means we can take it back any time for a brand-new one.”

“That’s another problem,” Morice said. “They couldn’t replace it with one that wasn’t broken.”

Diversification

Volkswagen’s best-selling product isn’t a car — it’s sausages. Item number 199 398 500 A in the Volkswagen parts catalog is currywurst sausage. In the 1940s and 1950s the company owned a pig farm to help feed factory employees, and today a team of butchers in VW’s Wolfsburg factory still makes 6.5 million 10-inch sausages every year using a secret recipe.

VW sells them in 11 countries, but the U.S. is not one of them, due to regulations regarding the import of processed pork products. There is hope, though: VW has said it may begin producing the sausages in the United States.

“We have been successful in offering Americans our German-engineered vehicles,” the company’s Clint Waddell told the Wall Street Journal. “We hope Americans may also enjoy a German-engineered currywurst.”

“Bike Keeps Family in Stitches”

Carrying four persons and a sewing machine, the world’s weirdest bicycle recently had a tryout in Chicago, Ill. The two-story vehicle, known as the ‘Goofybike,’ is the creation of Charles Steinlauf. It carries the whole Steinlauf family. The inventor rides at the top and guides the contraption by means of a huge automobile steering wheel. Mrs. Steinlauf sits below, operating a sewing machine, while her son pedals behind and her daughter rides on the handlebars in front. When the odd vehicle is at rest, the projecting legs of the sewing machine prevent the lofty cycle from tipping over.
