The Spirit Battery

https://books.google.com/books?id=FtEPAAAAYAAJ&pg=PA101

When the electric telegraph was making its appearance in the 1840s, it was strangely easy to confuse it with spiritualism: Both were uncanny means of talking with absent people through systems of symbols. In a bid for legitimacy, spiritualists appealed to the principles of “electrical science.” In his 1853 book The Present Age and Inner Life, Andrew Jackson Davis proposed a “spirit battery” by which a medium could improve her contact with the spirit world by asking her guests to hold a magnetic rope whose ends were dipped in water-filled buckets made of copper and zinc:

The males and females (the positive and negative principles) are placed alternately; as so many zinc and copper plates in the construction of magnetic batteries. The medium or media have places assigned them on either side of the junction whereat the rope is crossed, the ends terminating each in a pail or jar of cold water. … But these new things should be added. The copper wire should terminate in, or be clasped to, a zinc plate; the steel wire should, in the same manner, be attached to a copper plate. These plates should be dodecahedral, or cut with twelve angles or sides, because, by means of the points, the volume of terrestrial electricity is greatly augmented, and its accumulation is also, by the same means, accelerated, which the circle requires for a rudimental aura (or atmosphere) through which spirits can approach and act upon material bodies.

“We are negative to our guardian spirits; they are positive to us,” Davis wrote. “The whole mystery is illustrated by the workings of the common magnetic telegraph. The principles involved are identical.”

Alarming bonus factoid: When Samuel Morse appeared before Congress in 1838 to seek funding for an experimental telegraph line, some congressmen introduced amendments that would provide funds for research on mesmerism as well. The committee chair wrote, “It would require a scientific analysis to determine how far the magnetism of mesmerism was analogous to the magnetism to be employed in telegraphs.” When the bill came to a vote, 70 congressmen left their seats; many hoped “to avoid spending the public money for a machine they could not understand.”

In 1784 French architect Laurent Vaudoyer introduced a design for a spherical house. The living space is at the “equator,” with a vestibule, dining room, salon, bedrooms, and closets. A pantry, toilets, and dressing rooms are squeezed in rather less conveniently, above and below.

The spherical shape was the point, write Ulrich Conrads and Hans Sperlich in The Architecture of Fantasy. “[O]nly afterwards was an attempt made to arrange the interior of the globe for use.”

Podcast Episode 256: Lasseter’s Reef

https://commons.wikimedia.org/wiki/File:Gibson_Desert_and_moon_from_Alfred_%26_Marie_Range.jpg

In 1930 Harold Lasseter claimed he’d discovered an enormous deposit of gold in the remote interior of Australia, and a small group of men set off into the punishing desert in search of a fortune estimated at 66 million pounds. In this week’s episode of the Futility Closet podcast we’ll tell the story of Lasseter’s reef, one of the most enduring legends of the Australian outback.

We’ll also reconsider the mortality rates of presidents and puzzle over an unlocked door.

All new ventures have their detractors, and James had his full share with the Cavendish project. One diminishing but still powerful school of critics held that, while experiments were necessary in research, they brought no benefit to teaching. A typical member was Isaac Todhunter, the celebrated mathematical tutor, who argued that the only evidence a student needed of a scientific truth was the word of his teacher, who was ‘probably a clergyman of mature knowledge, recognised ability, and blameless character’. One afternoon James bumped into Todhunter on King’s Parade and invited him to pop into the Cavendish to see a demonstration of conical refraction. Horrified, Todhunter replied: ‘No, I have been teaching it all my life and don’t want my ideas upset by seeing it now!’

Instructions

In December 1968, kidnappers abducted 20-year-old university student Barbara Jane Mackle from her family’s home in Coral Gables, Fla., drove her to a remote pine stand near Norcross, Ga., and buried her in a box. Inside she found this message:

DO NOT BE ALARMED. YOU ARE SAFE.

YOU ARE PRESENTLY INSIDE A FIBERGLASS REINFORCED PLYWOOD CAPSULE BURIED BENEATH THE GROUND NEAR THE HOUSE IN WHICH YOUR KIDNAPPERS ARE STAYING. YOUR STATUS WILL BE CHECKED APPROXIMATELY EVERY 2 HOURS.

THE CAPSULE IS QUITE STRONG, YOU WILL NOT BE ABLE TO BREAK IT OPEN. BE ADVISED, HOWEVER, THAT YOU ARE BENEATH THE WATER TABLE. IF YOU BREAK OPEN A SEAM YOU WOULD DROWN BEFORE WE COULD DIG YOU OUT. THE CAPSULE INSTRUMENTATION CONTAINS A WATER SENSITIVE SWITCH WHICH WILL WARN US IF THE WATER ENTERS THE CAPSULE TO A DANGEROUS DEGREE.

YOUR LIFE DEPENDS ON THE AIR DELIVERED TO YOUR CHAMBER VIA THE VENTILATION FAN. THIS FAN IS POWERED BY A LEAD-ACID STORAGE BATTERY CAPABLE OF SUPPLYING THE FAN MOTOR WITH POWER FOR 270 HOURS. HOWEVER, THE USE OF THE LIGHT AND OTHER SYSTEMS FOR ONLY A FEW HOURS COUPLED WITH THE HIGHER AMPERAGE DRAIN WILL REDUCE THIS FIGURE TO ONLY ONE WEEK OF SAFETY.

SHOULD THE AIR SUPPLIED PROVE TO BE TOO MUCH YOU CAN PARTLY BLOCK THE AIR OUTLET WITH A PIECE OF PAPER. A MUFFLER HAS BEEN PLACED IN THE AIR PASSAGE TO PREVENT ANY NOISE YOU MAKE FROM REACHING THE SURFACE: IF WE DETECT ANY COMMOTION WHICH WE FEEL IS DANGEROUS, WE WILL INTRODUCE ETHER TO THE AIR INTAKE AND PUT YOU TO SLEEP.

THE FAN OPERATES ON 6 VOLTS. IT HAS A SWITCH WITH TWO POSITIONS TO SWITCH BETWEEN THE TWO AVAILABLE CIRCUITS. SHOULD ONE CIRCUIT FAIL TURN TO THE OTHER.

THE BOX HAS A PUMP WHICH WILL EVACUATE ANY ACCIDENTAL LEAKAGE FROM THE BOX WHEN YOU TURN THE PUMP SWITCH ON TO THE “ON” POSITION. THIS PUMP USES 15 TIMES AS MUCH POWER AS YOUR VENTILATION FAN (7.5 AMPS); YOUR LIFE SUPPORT BATTERY WILL NOT ALLOW USE OF THE PUMP EXCEPT FOR EMERGENCY WATER EVACUATION.

THE LIGHT USES 2.5 TIMES THE AMPERAGE OF THE AIR CIRCULATION SYSTEM. USE OF THE LIGHT WHEN NOT NECESSARY WILL CUT YOUR BATTERY SAFETY MARGIN SUBSTANTIALLY. IF YOU USE THE LIGHT CONTINUOUSLY YOUR LIFE EXPECTANCY WILL BE CUT TO ONE THIRD OF THE WEEK WE HAVE ALLOTTED YOU BEFORE YOU ARE RELEASED.

YOUR CAPSULE CONTAINS A WATER JUG WITH THREE GALLONS OF WATER AND A TUBE FROM WHICH TO DRINK IT. BE CAREFUL TO BLOW THE WATER FROM THE TUBE WHEN YOU ARE FINISHED DRINKING TO AVOID SIPHONING THE WATER ONTO THE FLOOR WHEN THE TUBE END DROPS BELOW THE WATER LEVEL.

YOUR CAPSULE CONTAINS A BUCKET FOR REFUSE AND THE PRODUCTS OF YOUR BOWEL MOVEMENTS. THE BUCKET HAS AN ANTIBACTERIAL SOLUTION IN IT: DON’T TIP IT OVER. THE LID SEALS TIGHTLY TO PREVENT THE ESCAPE OF ODORS. A ROLL OF WAX PAPER IS PROVIDED – USE IT TO PREVENT SOLID WASTE FROM CONTAMINATING YOUR BED. KOTEX IS PROVIDED SHOULD YOU NEED IT.

BLANKETS AND A MAT ARE PROVIDED. YOUR WARMTH DEPENDS ON BODY HEAT SO REGULATE THE AIR TO PREVENT LOSS OF HEAT FROM THE CAPSULE.

A CASE OF CANDY IS PROVIDED TO FURNISH ENERGY TO YOUR BODY.

TRANQUILIZERS ARE PROVIDED TO AID YOU IN SLEEPING – THE BEST WAY YOU HAVE TO PASS THE TIME.

THE VENTILATION SYSTEM IS DOUBLY SCREENED TO PREVENT INSECTS OR ANIMALS FROM ENTERING THE CAPSULE AREA. YOU RISK BEING EATEN BY ANTS SHOULD YOU BREAK THESE PROTECTION SCREENS.

THE ELECTRICAL COMPONENTS BEHIND THESE SCREENS ARE DELICATE AND THEY SUPPORT YOUR LIFE. DON’T ATTEMPT TO TOUCH THESE CIRCUITS.

WE’RE SURE YOUR FATHER WILL PAY THE RANSOM WE HAVE ASKED IN LESS THAN ONE WEEK. WHEN YOUR FATHER PAYS THE RANSOM WE WILL TELL HIM WHERE YOU ARE AND HE’LL COME FOR YOU. SHOULD HE FAIL TO PAY WE WILL RELEASE YOU, SO BE CALM AND REST – YOU’LL BE HOME FOR CHRISTMAS ONE WAY OR THE OTHER.

The kidnappers demanded $500,000 from Mackle’s father, a wealthy Florida land developer. While he was arranging a ransom drop, the FBI identified the lead kidnapper as Gary Steven Krist of the University of Miami. When he received the money, Krist called the FBI and gave directions to the box, where Mackle had spent 83 hours underground. When agents tore it open she said, “You’re the handsomest men I’ve ever seen.”

The kidnappers were quickly captured. Krist was sentenced to life in prison, and his accomplice, Ruth Eisemann-Schier, got seven years.

Dispensationalist pastor Clarence Larkin illustrated his books with intricate charts interpreting prophecy and explaining God’s action in history.

“[T]he charts had to be thought out and developed under the direction and guidance of the Holy Spirit,” he wrote in Dispensational Truth (1920). “In this the Holy Spirit did not confuse the Author by suggesting all the charts at one time. When one was completed another was suggested. And upon more than one occasion when a problem arose the answer was given in the night or at awakening in the morning.”
