Numbers Game

On June 18, 1964, an elderly woman was walking through a Los Angeles alley when a blond woman with a ponytail pushed her to the ground and stole her purse. The blond woman escaped in a yellow car driven by a bearded black man.

Police arrested Janet Collins, a ponytailed blond woman whose bearded black husband drove a yellow Lincoln. At trial, a local mathematics instructor testified that there was 1 chance in 12 million that another couple would meet this description, and the jury convicted the Collinses of second-degree robbery. Sound reasonable?

Well, no. The California Supreme Court reversed the conviction, noting that the prosecution had offered no statistical evidence and that the mathematician had simply invented estimates for each of the six factors and multiplied them together, without adjusting for dependence or the possibility of mistake.

“The testimony as to mathematical probability infected the case with fatal error and distorted the jury’s traditional role of determining guilt or innocence according to long-settled rules,” wrote justice Raymond Sullivan. “Mathematics, a veritable sorcerer in our computerized society, while assisting the trier of fact in the search for truth, must not cast a spell over him.”

Looking Up

Charles Clerke was midshipman on HMS Dolphin during her first circumnavigation of the world, under John Byron. Immediately on his return in April 1767, he appeared before the Royal Society with an account of enormously tall natives in Patagonia:

They are of a copper colour, with long black hair, and some of them are certainly nine feet, if they do not exceed it. The Commodore, who is very near six foot, could but just reach the top of one of their heads, which he attempted on tip-toes; and there were several taller than him on whom the experiment was tried. They were prodigious stout, and as well and proportionally made as ever I saw people in my life. The women, I think, bear much the same proportion to the men as our Europeans do: there was hardly a man there less than eight feet, most of them considerably more; the women, I believe, run from seven and a half to eight feet. (Philosophical Transactions, vol. 57)

By that time such reports had been accumulating for more than two centuries: See Tall Tale and More Tall Argentines.

Hell’s Bells

Some thirty years ago, there was published an English book, that received considerable attention, entitled ‘Bealings Bells.’ The principal statements are as follow: On February 2, 1834, the bells in Major Moor’s residence, at Great Bealings, began to ring, without any visible cause, and continued to do so daily for nearly two months. A row of nine bells was almost constantly in motion, at times all of them ringing at once, at other times only five. The ringing was witnessed by a great number of people, and many efforts were made to discover the agency, but in vain. Major Moor published an account of the annoyance in the Ipswich Journal, and, much to his surprise, received numerous letters from different parts of the kingdom, giving accounts of similar ringings, occurring at about the same time. At Greenwich Hospital, the phenomena took place under so remarkable circumstances as to excite general attention. All persons were excluded from the apartments where the bell-pulls were, and the bells were watched night and day. In some localities, where the ringings were heard, the bell-pulls were cut, to end the disturbance; but the bells rang on as merrily as ever. When once under way, they seemed to be electrified; nothing could stop them but force.

Apathy Repaid

Choir practice normally started at 7:20 p.m. at the West Side Baptist Church in Beatrice, Neb. But on March 1, 1950, all 15 members were late.

One pair of sisters had car trouble; they called for a ride from a third member, who was delayed by homework. A mother and daughter were detained at a relative’s house. The choir director was late because her daughter, the pianist, had fallen asleep. Other members needed to finish a letter or hear the end of a radio program. One was “just plain lazy.”

So no one was there at 7:25 when the building exploded. The blast shattered local windows and forced a nearby radio station off the air.

The church furnace, it seems, had ignited a gas leak.

Sound Reasoning

Wintering in the Canadian Arctic in 1822, Capt. W.E. Parry made a series of experiments to see whether cold affects the velocity of sound. He marked a line of 5,645 feet on the sea ice, put a six-pounder gun at one end, and stood with a second observer at the other end. The gun fired 15 blank charges, and the observers timed the interval between each flash and its report. Generally they got good results, giving a mean velocity of 1,023 feet per second. But, writes Mr. Fisher:

The Experiments on the 9th February, 1822, were attended with a singular circumstance, which was–the officers’ word of command ‘fire,’ was several times distinctly heard both by Captain Parry and myself, about one beat of the chronometer [half a second] after the report of the gun; from which it would appear, that the velocity of sound depended in some measure upon its intensity.

“The word ‘fire’ was never heard during any of the other experiments; upon this occasion the night was calm and clear, the thermometer 25° below zero, the barometer 28.84 inches, which was lower than it had ever been observed before at Winter Island.” The phenomenon, whatever it was, has never been observed elsewhere, but Parry noted another acoustic oddity on his next voyage.

A Giantess Gives Birth

Back in 2005 we noted that 7’9″ M.V. Bates had married 7’5″ Anna Swan in 1871. They conceived two sons; the first was stillborn, but the second was delivered successfully in 1879, weighing 23.75 pounds. Obstetrician A.P. Beach published an account of the delivery that year in the New York Medical Record. Excerpts:

  • “After a convenient time, with my patient in the usual position, I proceeded to make an examination, but was unable to reach the os uteri, it being so far up. I could not, with my hand, by any ordinary effort, make a satisfactory examination, but concluded that she was in the initial stage of labor.”
  • “At 4 P.M., on the 18th, while conducting an examination during pain, the membranes gave way spontaneously and the amniotic fluid came pouring out so profusely as to startle every one. … The bed was well protected by rubber blankets, which carried the waters over the side of the bed, where they were caught in vessels to the amount of five gallons.”
  • “The forceps could not be successfully applied because of the unusually large head which lay, with the neck, in a vagina that would measure on its posterior aspect 12 inches at least, and from 7 to 9 in its anterior.”
  • “After further consultation, as it was our great desire to deliver if possible, without mutilation, we passed a strong bandage over the neck of the child, and while one made downward and lateral traction, the other, after several attempts, succeeded in bringing down an arm, and finally after a laborious seige we succeeded in delivering our patient of a male child.”

“We believe that this is the largest infant at birth of which there is any authenticated record,” note the editors. “The placenta usually weighs one-sixth as much as the foetus. In this case the secundines in all weighed nearly half as much as the child.”
