110 Report on the Progress oftlie Magnetic Survey, [No. 2. 



2. Prom S. S. W. to N. N. E., which is the line of the Western 

 Ghauts. On the Neilgherries these two directions of disturbance 

 actually meet. The former one is clearly represented by the 

 direction of Eastern border of the Neilgherry plateau and by the 

 Dodabetta range, the latter one by the fine mountain range of the 

 Koondahs, which rise to the South and South-West of Ootacamund. 



3. Lines of extensive faults are clearly traceable on the Mysore 

 plateau, running from West to East. The direction of some of 

 the principal rivers, as the Mayar, the Cavery, &c, is connected 

 with them. Along the valley of the Mayar the fault 13 very clearly 

 visible. 



4. A fourth line of disturbance runs from North to South 

 through the Mysore country. It is less marked by the direction 

 of the planes of cleavage or foliation than by extensive dykes of 

 greenstone and of a fine large-grained granite, which run in this 

 direction often for many miles. 



An Account of a Journey across the Chains of the Kuenluen, from 



Ladalc to Khotan. — By Hermann and Robert Schlagintweit, 



Esqs. 



Proceeding from Ladak through Nubra to the Pass of Karakorum, 

 we were able to pass the frontier of Ladak and to extend our obser- 

 vations over very nearly the whole breadth of the Kuenluen moun- 

 taiDS. We estimate (not having yet reduced our astronomical 

 observations of latitudes and longitudes) tbat the distance we tra- 

 velled in Turkistan before returning again into the Thibetan terri- 

 tory is very nearly 300 English miles. 



We left Ladak July 24th, and went by the Laoche Pass 

 (17,600 feet*) to the valley of the Shayok and to JNubra. Prom 

 Nubra we crossed the Sassar Pass, about 17,500 feet. We stayed 

 two days in the Pass itself to make Magnetic observations, and to 

 enable us to reach the summit of the Sassarla, (Sassar mountain 

 20,000 feet) from which we had, as we anticipated, a very extensive 

 and interesting view of the large groups of glaciers surrounding the 

 Pass, one of the largest accumulation of glaciers in the Kuenluen. 



* The heights given in this Report are only approximations. Very good corre- 

 sponding observations were taken at Ladak, but we have not yet been able to 

 calculate them in detail.
