The children had been found dead in Eric's parked car, and there was ample evidence that, in their case, at least, the popular belief that cyanide of potassium causes quick and painless death was untrue...
...Somewhere along in here I began to get excited about magnets, and I remember discovering electric bells and batteries. With my allowance I bought a pound of wire, a battery and a bell--I guess I was fourteen. I made batteries with potassium dichromate dissolved in sulfuric acid.

And fresh water, when inhaled into the lungs, does far more damage than salt: it evidently dilutes the blood, breaks down red cells, overfills the heart, destroys the body's balance of sodium and potassium salts, and usually causes the heart to twitch uselessly...
...veins. But to understand any one of these mechanisms, young Dr. Moore realized, demanded understanding of broader and more fundamental subjects. What is the body's normal content of such common components as water, sodium and potassium? What changes occur after injury or surgery?

A medical team traced her trouble to a small tumor on her right adrenal gland, which was pumping out a flood of aldosterone although there was no excess of other adrenal hormones. Surgeons removed her tumor, and now, eight years later, the woman...
