out that it was necessary to distinguish, if possible, between what the 
Rev. Vicar Apostolic knew by personal observation or inquiry, and 
what was merely preconception derived from the maps in his posses- 
sion. He showed that he was completely imbued with the notions 
regarding the rivers of Thibet which are set forth in the maps of 
Klaproth, and in Berghaus’s map of Further India (1843), and was 
misled by these. The reasons for entirely rejecting the identity of 
the great Dzanbo and the Irrawadee were given shortly. The very 
fact that he attributed the locality of the murder of Krick and 
Boury to the banks of a river running into the Irrawadee was shown 
to disprove his notions, as the locality of that murder was known to 
be near the great Dihong in the Mislnni country. It was singular 
that the only common basis of geographical knowledge between 
British India and the Thibetan missionary should be the tragical 
murder of those two reverend fathers. 
Major Dalton, formerly principal Assistant Commissioner at 
Lukhimpoor in Upper Assam, who was present at the meeting, then 
made some very interesting remarks from his intimate knowledge of 
that country and the tribes surrounding it. He corrected Colonel 
Yule’s belief that the Missionaries had been murdered near the 
Dihong. They were actually on their way into Thibet by the route 
of the real or eastern Brahmaputra (above the Brahmakoond) and had 
reached a Thibetan village where they stopped some time, when they 
were murdered by Kesa a Mishmi chief. 
Colonel Yule pointed out that this was a most valuable correction, 
and much more easily reconciled with the distance from Bonga on 
the Loo-kiang stated by M. de Mazure. It seemed to prove also 
that the Gakbo-dzangbo of the maps, the Kanpo of M. de Mazure, 
and the Kenpou of d’Anville was actually the eastern Brahmaputra. 
Major Dalton mentioned that the hill people about the Dihong 
were uniform in their statement that the river came from Thibet. 
That river and the eastern Brahmaputra were the enly rivers of 
Assam, they generally maintained, that did come from Thibet. He 
also mentioned a curious tradition among the people that some 
centuries ago the Dihong did not exist, but appeared suddenly in 
vast irruption through the mountains. 
He spoke with authority on the subject of the murdered mis- 
sionaries as the arrangements that led to the capture of the murderer
