which the dome is visible, a comparatively low saddle is 

 situated, which must be the true Tasman Saddle, and at the 

 right of the peak another saddle, which must lead into the 

 Whymper Glacier, on the West Coast watershed. 



Speaking on this point — viz., the orographical features of 

 tlie Liebig Eange — von Haast says, "Between the Tasman 

 and Murchison Glaciers lies the bold and picturesque Malte 

 Brun Eange, appearing like an island, the Murchison Glacier 

 having at no distant date joined the former, and thus sur- 

 rounded this lofty snow-capped ridge. From Mount Darwin, 

 the convergent range still continues its southern direction, 

 where .... in the Liebig Eange the glacier- sources of 

 the Eiver Cass .... are situated." According to our 

 observations, of course, it will be seen that Mount Darwin 

 has no connection with the Liebig Eange, neither is it on the 

 main range, but is enclosed, iciifi tlie Malfc Brun Bangc, by 

 the Murchison and Tasman Glaciers. 



Following with the eye the summits of the Liebig Eange 

 from the point of its divergence from the main chain, a short 

 distance east of the Whymper Saddle, a fine array of peaks 

 and glaciers presents itself. Situate iii the big bend of the 

 range is one mountain of toothlike form, which presents a 

 remarkably imposing appearance, and seems to drain into the 

 Classen Glacier from its opposite slopes ; whilst just to the 

 east of it is situate a low snow-saddle, possibly leading into 

 that glacier. I cannot find this peak marked on any map 

 extant. 



Even supposing our conclusions regarding the topography 

 of this locality to be Nvi-ong, there must be ascribed a far 

 greater importance to the Murchison Glacier and Liebig Eange 

 than that given to it on any existing map. Oui* aneroid gave 

 the height of our standpoint as 8,300ft., but this would pro- 

 btibly be some hundreds of feet in excess of the true height. 

 From the appearance of the saddle leading into the Tasman, 

 and the crevasses around its base, we considered that it might 

 prove impracticable even to a well-equipped alpine party. 



The Eetuen-joukney. 

 Coming down to the saddle again, a decision to return by 

 our upward route was quickly formed, for our distressed man 

 Avas lying exhausted on the snow, and suffering from a severe 

 attack of vomiting. Some people call this malady "mountain 

 sickness," believing it to be brought on mainly by rarity of the 

 air, and it is an evergreen subject for discussion amongst 

 climbers ; but most practised mountaineers incline to the 

 l^elief that the sole cause of it is undue exertion when' out of 

 training : and in this case such a conclusion would be justi- 

 fiable, for the subject affected had not been a week off 'board-
