severest hunger that any one with ordinary presence of mind 
need fear to meet the most powerful of these brutes, entirely 
unarmed.f 
Thirdly, we have here, and may retain without the necessit; 
protective measures, a large number of invertebrate animals whose 
habits are little known, and whose structure has scarcely b | 
investigated, and this remark will apply as well to the lower 
members of the vertebrate series. There is, perhaps, much reason : 
to look for a peculiar fauna in this restricted region, both on 
account of its altitude and its comparatively isolated position, as Í 
well as the severity of the climate at certain seasons of the yont
