_Sylhet._--On the southern frontier we have Kukis; on the eastern Cachari; on the northern Coosyas (_Kasia_). Due west of these last lie the Garo. I imagine that both these last-named populations are members of the same group--but cannot speak confidently. If so, we have departed considerably from the more typical Burmese of Arakhan and Ava. Still we are within the same great class. The Garo will command a somewhat full notice. The Cachars depart still more from the more typical Burmese; the group to which they most closely belong being one which will also be enlarged on. North of the Kasia we reach the western portion of the southern frontier of-- _Assam._--Here it will be convenient to take the whole of the valley--Upper as well as Middle and Lower Assam--although parts of the former are independent rather than British--and to go round it; beginning with the Kasia country and the Jaintia mountains on the south-west. I imagine--but am not certain--that the Kasia and Jaintia mountaineers are very closely allied. Next to the Cachars on the southern, or Manipur, frontier are-- _The Nagas._--These are in the same class with the Kuki; _i.e._, the wild tribes of Manipur, speaking a not very altered dialect of the Burmese. _The Singpho._--This people is said to have come from a locality between their present position and the north-eastern corner of Assam and the Chinese frontier. An imperfect Buddhism, and an unappreciated alphabet of Siamese origin, are the chief phenomena of their civilization. _The Jili._--These are conterminous with the Singpho; to whom they are closely allied, in language, at least; seventy words out of one hundred agreeing in the two vocabularies. The _Khamti_ come in now. These have been mentioned as Tha'y in their most northern localities. They occupy north-eastern Assam, and are conterminous with the Singpho. The Khamti language, with its per-centage of ninety-two words common to it and the Siamese of Bankok, ten degrees southwards, has only three out of one hundred that agree with the Singpho, and ten in one hundred with the Jili. This shows the remarkable character of their ethnological distribution, and, at the same time, suggests the idea of great displacement. _The Mishimi._--These occupy the north-east extremity of Assam. With the Mishimi we turn the corner, and find ourself on the northern or Tibetan frontier. Here it is the most western tribes which come first; and these are-- _The Abors and Padam Bor-Abors._--The first, like the Kuki, on the mountain-tops; the latter, like the Khumia, on the lower ranges. _The Dufla._--Mountaineers west of the Abors, with whom they are conterminous in about 94° East lon. _The Aka._--Mountaineers west of the Dufla, with whom they are conterminous in about 92° East lon. The Akas bound Lower Assam, the eastern part of which lies between them and the Cachari country.
