the testimony of the jibijssinian Dean strictly 
confirmed all that Bruce had written upon the 
subject. He told us, that horses and cows were 
its principal victims ; that there were not many 
of those insects in his native province ; but that 
he had heard of armies being destroyed in con- 
sequence of this terrible scourge. We ques- 
tioned him concerning the plant which is said 
to render persons invulnerable to serpents or 
scorpions, merely by chewing its leaves. He 
replied, that he knew the plant well, but had 
forgotten its name ; that it resembled hemp, 
and that he had often made use of it to prove its 
virtues ; but he added, that it must be chewed 
at the time of touching the serpent or the 
scorpion. 
Previous to the introduction of any inquiry 
concerning the source of the Nile, we shewed 
to him Bruce's map of the Lake Tzana, and of 
the surrounding country. At this he was highly 
gratified. He knew all the places mentioned 
in the territories of Belessen, Begemder, Gojam, 
and Agows; and, attempting to shew us the 
situation of GoNDAR, actually pointed out the 
spot marked by Bruce for the locality of that 
city.
