degrees ; and to thefe lamellae others like them ad- 
hered, fome greater and fome lefs, but moft of the 
latter - y and others various like the fortifications of 
cities appeared to be joined to long hexangular fpi- 
culae, and plane hexangles of equal fides. 
In one day and night I found fifteen, twenty or 
more particles of fnow differently formed ; fuch as 
Olaus Magnus mentions ; and in the year 1740, on 
the nth, 12th, 13th, 21ft, and 23d of January, and 
alfio on the 6th, 23 d, and 2 + th of February, I had 
an opportunity of delineating eighty different ad- 
mirable figures of fnow, and of obferving their num- 
berlefs varieties. 
And although a vaft variety of thefe configurations 
of fnow may fail or vanifh in the fame moment, yet 
the fmaller particles, from their various combination 
with one another, conftituting this wonderful variety 
of configurations of the fnow, were obferved by me 
to be comprehended under thefe following forms, 
viz. of parallelograms, or oblong, ft-rait, or oblique 
quadrangles, rhombs, rhomboids, trapezia, or of 
hexangular forms of equal or unequal fides, whofe 
angles are fixty degrees ; and thefe hexangular parti- 
cles were far more numerous than thole of any other 
form mentioned. 
The natural fize of moft of the finning quadran- 
gular particles, and of the little fiars of fnow, as well 
the limple as the lefs compound ones, does not ex- 
ceed the twentieth part of an inch : nor do the more 
compound particles the fifth of an inch. For the 
natural magnitude or rather fmallnefs, fee fig. 4. 6* 
8. 9. 10. 35. 37. 39. 40* 44- to 47. and 61. 
Thefe beautiful various configurations to the num- 
ber of 91, are in Tab, xx. and xxi.
