e wrote a
book called "The Ancient Physician's Legacy to His Country," which ran
into seven or eight editions, in which he strongly recommended the
administration of large doses of quicksilver for almost every malady that
man is subject to. This book won him the nickname of the "Quicksilver
Doctor." He invented a diaphoretic powder containing ipecacuanha and
opium, which is used to this day, and is still known as Dover's powder.

Dover died at the age of 82, in the year 1742, and should always be
remembered for having invented Dover's powders, commanded a company of
Marines, rescued Alexander Selkirk, written a most extraordinary medical
book, and for having been a successful pirate captain.

DOWLING, CAPTAIN WILLIAM.

Of New Providence, Bahamas.

Hanged for piracy in the early part of the eighteenth century.

DRAGUT. Barbary corsair.

Started life as a pirate, and was eventually put in command of twelve
large galleys by Kheyr-ed-din. Pillaged and burnt many towns on the
Italian coast, and destroyed ships without number. Was taken prisoner by
the younger Doria, and condemned to row in the galleys for four years
until ransomed for 3,000 ducats by Kheyr-ed-din. Appointed Admiral of the
Ottoman Fleet. Ended a bloodthirsty but very successful career in 1565 by
being killed at the Siege of Malta.

DRAKE, SIR FRANCIS.

Born about 1540.

The life of the famous Admiral is too well known to require more than a
bare notice in these pages. Although the Spaniards called him "the
Pirate," he was more strictly a buccaneer in his early voyages, when he
sailed with the sole object of spoiling the Spaniards. His first command
was the _Judith_, in John Hawkins's unfortunate expedition in 1567. Drake
made several voyages from Plymouth to the West Indies and the Spanish
Main.

In 1572 he burnt Porto Bello, and a year later sacked Vera Cruz. He served
with the English Army in Ireland under Lord Essex in 1574 and 1575. In
1578 he sailed through the Straits of Magellan, plundered Valparaiso, and
also captured a great treasure ship from Acapulco. Sailing from America,
he crossed the Pacific Ocean, passed through the Indian Archipelago,
rounded the Cape of Good Hope, and arrived at Deptford in England in 1581.
At the conclusion of this voyage he was knighted by Queen Elizabeth, being
the first Englishman to sail round the world. Drake's voyages after this
were sailed under commission and letters of marque, and so lose any stig
