</p>
<ol><li>The ranges E. of Pundim &amp; W. of the Lachen River have not been visited, nor the E. heads of G. Rungeet.</li>
<li>Bhomtso (Thibet) was well determined from bearings of K'junga. Dn 2 &amp; Chumalari, but the summit of Donkiah was not recognized from any point near the heads of Lachen and Lachoong. The positiosn of the Snowy Peaks &amp;c threreabouts may be 1 or 2 miles wrong in position.</li>
<li>The position Tukchawm also requires confirmation to 2 miles.</li>
<li>The route &amp; positions from Tumloong to Cheadam are but approximates, owing to circumstances over which I had no control.</li>
<li>The country W. of Gipmochi, position of Yakla Pass, frontier of Sikkim S. of Chola and lower course of Teesta River are unknown.</li></ol>
