in length and 3 ft. in breadth, and indicates an
animal exceeding the elephant in size. The upper jaw is apparently
destitute of incisor and canine teeth, but possesses five molars on each
side, with a corresponding number in the jaw beneath. The most
remarkable feature, however, consists in the front part of the lower jaw
being bent downwards and bearing two tusk-like incisors also directed
downwards and backwards. _Dinotherium_ is a member of the group
Proboscidea, of the line of descent of the elephants.

DINWIDDIE, ROBERT (1693-1770), English colonial governor of Virginia,
was born near Glasgow, Scotland, in 1693. From the position of customs
clerk in Bermuda, which he held in 1727-1738, he was promoted to be
surveyor-general of the customs "of the southern ports of the continent
of America," as a reward for having exposed the corruption in the West
Indian customs service. In 1743 he was commissioned to examine into the
customs service in the Barbadoes and exposed similar corruption there.
In 1751-1758 he was lieutenant-governor of Virginia, first as the deputy
of Lord Albemarle and then, from July 1756 to January 1758, as deputy
for Lord Loudon. He was energetic in the discharge of his duties, but
aroused much animosity among the colonists by his zeal in looking after
the royal quit-rents, and by exacting heavy fees for the issue of
land-patents. It was his chief concern to prevent the French from
building in the Ohio Valley a chain of forts connecting their
settlements in the north with those on the Gulf of Mexico; and in the
autumn of 1753 he sent George Washington to Fort Le Boeuf, a newly
established French post at what is now Waterford, Pennsylvania, with a
message demanding the withdrawal of the French from English territory.
As the French refused to comply, Dinwiddie secured from the reluctant
Virginia assembly a grant of L10,000 and in the spring of 1754 he sent
Washington with an armed force toward the forks of the Ohio river "to
prevent the intentions of the French in settling those lands." In the
latter part of May Washington encountered a French force at a spot
called Great Meadows, near the Youghiogheny river, in what is now
south-western Pennsylvania, and a skirmish followed which precipitated
the French and Indian War. Dinwiddie was especially active at this time
in urging the co-operation of the colonies against the French in the
Ohio Valley; but none of the other governors, except William Shi
