ment turned towards tlie soutli-west, looking over the chaos of seracs of the 

 glacier des Bossons. I gathered nineteen species. M. Venance Payot of 

 Chamounix, made a fresh ascent to these locks on the 30th August, 1861, 

 and then found five species which I had not remarked. I give helow a list 

 of these twenty-four plants, of which five printed in italics, helong also to 

 the Flora of Spitzhergen. At the Grands Mulcts, as we shall see, the propor- 

 tion of Spitzhergen plants is twenty-one per cent., and with the exception of 

 Agrostis rupestris, there is not a single Lapland sj)ecies. Ihisflorula is then 

 composed of species exclusively sujper-alpine (tres-alpine) mixed with a fifth of 

 Spitzhergen plants. The Grand Mulcts is one of the highest stations of a 

 rodent {Arvicola nivalis, Mart.), the Snow Vole, which derives its nourish- 

 ment from the plants found in our list. M. Payot has besides gathered at 

 the Grands Mulcts, twenty-six mosses, two Hepaticge and twenty-eight 

 lichens giving a total of eighty species of plants on these apparently 

 barren rocks.

 Let us now see if our law is confirmed on Monte Rosa. Buring a 

 sojourn of fourteen days, from the 13th to 27th September, 1851, in the 

 cabin of Vincent, on the southern side of Monte Rosa, and at an elevation of 

 3,158 metres (10,368 feet), M.M. A. and H. Schlagintweit gathered, around 

 this station, on the Gneiss, forty-seven species of Phanerogamia, of which 

 ten (in italics in the subjoined list) form a part of the flora of S]3itzbergen.
