NATIONAL INSTITUTE. 
HE following interefting memoir, re- 
fpecting the red colour of the-frow 
on high mountains, was lately read be- 
fore the National Inftitute, by M. Ra- 
MOND. : 
_ When M. de Sauffure travelled in the 
Upper Alps, about twenty years ago, he 
remarked, for the firit time, that immenfe 
fields of {now were tinged by a red pow- 
iden, the origin of which he could not af- 
certain. ‘fo accomplifh this object, he 
colle&ted fome of the powder, and fub- 
jeSted it to experiments, but his doubts 
on this head were far from bemg cleared 
up; for, although it appeared to be of a 
vegetable nature, his attempts to difcover 
the plant to which it belonged did not fuc- 
ceed. This la confideration at firt in- 
adeced him to regard it as the product of 
a fingular combination of fome earth, fe- 
parated from the fnow with air and light : 
but he afterwards returned to his firft opt- 
nion, and regarded it as the feminal duft 
ef fome plant, probably of the cryptoga- 
ynous kind. He was farther confirmed in 
this opinion on his afcent to the fummit 
wf Mont Blanc, when he refleé&ted that the 
{now was never found tinged with this red 
matter, but at a certain and determined 
height, where many Alpine plants grew, 
and only during the feafon of their fecun- 
dation; and that at’ the fummit of this 
mountain, which was wholly deftitute of 
vegetation, the fnow uniformly appeared 
of the molt perfect whitenefs. He was, 
befides, anxious to learn whether a fimilar 
phenomenon did not occur in other moun- 
tainous regions.: | 
« This circumftance,” fays M. Ra- 
mond, ** I had it lately in my power fully 
to afcertain, as I obferved that the fhow 
was of this red colour in the Upper Py- 
rennees. Many obfervations, it is true, 
have led me to draw conclufions very dif- 
ferent from thofe of M. de Sauffure, but 
they de not enablé me to add any thing to 
the faéts he has fo accurately defcribed. 
‘* Like that ilufrious naturalift, f 
have met with this coloured {now in the 
fpring-and during thaws, on meuntains 
at the height of between two thoufand 
and two thoufand four hundred metres. 
In fome places, I obferved this reddifh 
tint in the furrows produced by the melt- 
ing of the fnow ; but it was more parti-. 
cularly evident, and of a deeper fhade, at 
the junction of feveral furrows, where a 
multitude of riils had depofited this co- 
louring matter. I colleéted a portion of 
this {now, and allowed it to diflolve fpon- 
taneoufly. The fluid thus obtained be- 
came almoft immediately clear, and the 
red powder was precipitated to the si
