By means a uninterrupted volcanic deposits and a series of hills of 
various physical characters, the Alaghéz is in geological connexion 
* he with the lofty dome of the ‘table. land of Agmangan, which is partly 
I formed of eruptive matter of a doleritic nature. It stretches down in 
e a $.W. direction opposite Mount Ararat, along the oe (lake), 
and has a circumference of about 140 wersts. The level of the great 
crater-lake Kanly goell (Blood lake) gives the See sous state- 
ment of the elevation of this flat dome, viz. 9278 French feet. The 
State of age _ g the 8.W. and 8.E, sides of the Goktschai
