the north-east by the usurper known as Eukratidas, Demetrius 
had to leave his Panjab dominion unprotected, with the result 
of the further advance of the Parthian forces, which seem to 
have reached as far as Thanesar. The Chinese author of the 
Heo Han Shu speaks rather contemptuously of the kingdom of 
Magadha under Buddhist rule:—The Svabhavika sect (of 
Buddhists) forbid killing in either offence or defence, and the 
Yuehti had an easy task in occupying the land. According 
to the author, on the S.W. T’iencho (Northern India) reaches 
the western sea, and on the east it extends to P’wank’i (seem- 
ingly an early mention of Bengal). Eukratidas succeeded in 
making himself master of what remained of Baktria, and passed 
it on to his son, cir. 140 B.C. The son, who, according to 
Justin (xli), had had his father. whom he conceived too old, done 
to death—an ordinary occurrence amongst these Getic sovereigns, 
—was no more successful, and lost, Strabo says, to Parthia, bu

provinces. This seems to have been the last record of the once 
promising Greko-Baktrian kingdom, of which we hear nothing 
after Heliokles. ‘

continue the struggle were Kushan under the strong rule of the 
Geathlefs, and Kophéné and Gandhara, with their dependencies 
still administered by Parthia under satraps almost regal, of 
which in their coins we find abundant evidence. Phraates, the — 
Parthian king who succeeded Mithridates, had to take up arms 
against the Skythic tribes in the extreme north-east, and was 
killed in battle B.C. 128-127. He was succeeded by an uncle, 
w 
the inroads on Parthia itself from the ever restless peoples of t 
north-east seems for the time to have ceased. This respite doubt 
less, for the materials at our service are too indefinite to explain” 
the motives of action, influenced Mithridates in looking onee 
more to the west ; where a tempting bait was held out to him by 
complications in Armenia, and an opening for the extension of
