Jan. 11, 1858.] WAUGH ON MOUNTS EVEREST AND DEODANGA. 113 
surveyors have assigned the name of Dewalaghiri, hut far he it from 
me to assert that ihat is its veritable name. 
Mr. Hodgson is not probably less fallible than his predecessors, 
and yet Colonel Crawford places Dhayabang east of the meridian of 
Katmandu, nearly in the position of our Peak XXV., whereas an- 
other authority (Kirkpatrick) places it far west of that meridian ; 
and here it is quite evident that the same name would not be 
assigned to the same peak. That Mr. Hodgson can get a name to 
any peak I believe ; but that it will be the true name I do not 
believe, as a general rule. 
2nd. Mr. Hodgson gives a Memorandum on the Seven Cosis, 
with a sketch. The sketch has no scale, and is confessedly a 
roughly-drawn document not founded on survey. It can, therefore, 
hardly be admitted as evidence of anything, but I shall show reason 
to doubt its being in Mr. Hodgson’s favour. 
Mr. Plodgson in the paper asserts,— 1st, that there is a mountain 
called Bhairava Langur, or Deodanga ; 2nd, that that mountain is 
the source of the Bhutia Cosi ; 3rd, that it is the same as Mount 
Everest of Colonel Waugh ; 4th, that Mount Everest is in the place 
of the source of the Bhutia Cosi. 
I have said there is presumptive evidence of the first assertion. 
The second assertion rests solely on information which is not 
very reliable (as far as the experience of accurate surveyors goes) at 
the best; and is peculiarly liable to error in this case, as the 
Bhutia Cosi is only one of several confluent streams, and has never 
been seen, as far as I learn, in its separate form by any European; 
consequently its course must be liable to great error. 
Mount Everest is stated to be identical with the source of the river, 
as the occupant of the same position ; but, if this position be un- 
trustworthy, there is an end of this, and consequently the proposi- 
tion that both, being sources of the same river, are the same, falls to 
the ground. 
The real result is from this paper that, — 1st, there is a mountain 
called Deodanga the source of a river ; 2nd, that a stream called 
the Bhutia Cosi comes from a snowy mountain ; 3rd, that the 
coincidence of these two mountains is, to say the best, subject to 
doubt; and 4th, that there is no evidence to show the latitude, 
longitude, and height of Deodanga and Mount Everest to be iden- 
tical at all. 
If the sketch map be a true representation of the courses of the 
streams given, I believe Mr. Hodgson will be puzzled to find room 
for his other Cosis, giving each the feeding area necessary for its 
size.
