THE NATURALIST. 



in whicli M. Dollfuss-Ausset, stayed in 1864, from 22nd August to 3rd 

 September, the liigliest temperature noted by him during this period being 

 6°2 (43° Fahr.) and the lowest —16° (3° Fahr). We thus see that the 

 climate is as rigorous as that of Spitzbergen, and it is very probable that careful 

 botanising in the months of July, August, and September, would fur- 

 nish a notable proportion of species indigenous to Spitzbergen and JSTorthern 

 Lapland. 



CEYPTOaAMIA OF THE GEANDS MULETS. 



In the Naturalist, vol. ii. p. 97, we gave a list of the flowering plants 

 found at the Grands Mulets on Mont Blanc, extracted from a paper by Prof. 

 Chas. Martins of Montpellier, entitled " Two Scientific Ascents of Mont 

 Blanc." This list contained twenty-four species, and mentioned besides these 

 twenty-six Mosses, two Hepaticse, and thirty Lichens. By the kindness of 

 Prof. Martins we are now enabled to complete the florula of this isolated 

 tract, by the list of the Cryptogamia found there, furnished in a letter to the 

 Editors, dated 3rd ISTovember, 1865.
