Doc, you've got to help my husband...

"Doc, you've got to help my husband," a farmer's wife said frantically. "He thinks he's a racehorse. He wants to live in a stable; he walks on all fours and he even eats hay."
"I'm sure I can cure him," the doctor replied, "but it'll be very costly."
"Oh, money's no object," she responded. "He's already won two races."

Machine gun

In 1718, a "Defence" rapid-fire gun was patented by a London lawyer, James Puckle (1667 - 1724). It is sometimes considered an ancestor of the machine gun. It was, in effect, a flintlock revolver with a barrel 3 feet long and a bore of 1.25 inches. A pre-loaded "cylinder" held 11 charges and could fire 63 shots in 7 minutes. (This rate of 9 shots/min was three times quicker than the fastest infantryman.) The patent described it as "A portable gun or machine called a Defence, that discharges soe often and soe many bullets, and can be soe quickly loaded as renders it next to impossible to carry any ship by boarding," which indicates shipboard use was intended. British patent No. 418 (1718). He began manufacture at White Cross Alley factory in 1721.«[Image: (top) detail of gun (bottom) gun shown in patent drawing on tripod mount.]
