rley of
Massachusetts, was then much concerned about the western frontier, and
he could accomplish very little. His appeals to the home government,
however, resulted in the sending of General Edward Braddock to Virginia
with two regiments of regular troops; and at Braddock's call Dinwiddie
and the governors of Massachusetts, New York, Pennsylvania and Maryland
met at Alexandria, Virginia, in April 1755, and planned the initial
operations of the war. Dinwiddie's administration was marked by a
constant wrangle with the assembly over money matters; and its obstinate
resistance to military appropriations caused him in 1754 and 1755 to
urge the home government to secure an act of parliament compelling the
colonies to raise money for their protection. In January 1758 he left
Virginia and lived in England until his death on the 27th of July 1770
at Clifton, Bristol.

_The Official Records of Robert Dinwiddie, Lieutenant-Governor of
Virginia_ (1751-1758), published in two volumes, at Richmond, Va., in
1883-1884, by the Virginia Historical Society, and edited by R. A.
Brock, are of great value for the political history of the colonies in
this period.

DIO CASSIUS (more correctly CASSIUS DIO), COCCEIANUS (c. A.D. 150-235),
Roman historian, was born at Nicaea in Bithynia. His father was Cassius
Apronianus, governor of Dalmatia and Cilicia under Marcus Aurelius, and
on his mother's side he was the grandson of Dio Chrysostom, who had
assumed the surname of Cocceianus in honour of his patron the emperor
Cocceius Nerva. After his father's death, Dio Cassius left Cilicia for
Rome (180) and became a member of the senate. During the reign of
Commodus, Dio practised as an advocate at the Roman bar, and held the
offices of aedile and quaestor. He was raised to the praetorship by
Pertinax (193), but did not assume office till the reign of Septimius
Severus, with whom he was for a long time on the most intimate footing.
By Macrinus he was entrusted with the administration of Pergamum and
Smyrna; and on his return to Rome he was raised to the consulship about
220. After this he obtained the proconsulship of Africa, and again on
his return was sent as legate successively to Dalmatia and Pannonia. He
was raised a second time to the consulship by Alexander Severus, in 229;
but on the plea of ill health soon afterwards retired to Nicaea, where
he died. Before writing his history of Rome ([Greek: Rhomaika] or
