gan, arifes from his averting, that Mr. Edwards, 
in his defcription of that bird, fays, that it is twice 
as large. Mr. Edwards, however, only confiders 
the fize of the Hudfon’s Bay Lagopus as between 
that of a Pheafant and a Partridge ; in which he is 
.very accurate : the bird is not only evidently fo to the 
eye, but weighs three ounces more than a common 
Partridge [e], 
M. de BufFon likewife feems to make an unne- 
cefFary fpecies of Tetrao, under the name of le petit 
Tetras, a plumage variable ; as his principal argu- 
ment for this opinion is, that they are not found 
on the mountains, as the Lagopi are. 
Now, it is very clear, from the name given in the 
catalogue from Hudfon’s Bay to this bird, of the 
Willow Partridge, that it lives entirely in that part 
of the world on the plains j nor are there (it is be- 
lieved) any very high mountains in the neighbour- 
hood of our forts. 
When M. de BufFon, therefore, conceives, that 
the Lagopus is always endeavouring to find out 
fnow and ice, and that it carefully avoids the glare 
of the fun [/]; it fhould feem, that the obfervation 
is by no means generally true ; becaufe, though the 
rigour of a Hudfon’s Bay winter is great, yet the 
fummer is very pleafant, and the fnow foon difap- 
pears, without which M. de BufFon imagines that 
the bird cannot exiflj though his ninth plate re- 
prefents the Ptarmigan, in his winter drefs,- fur- 
[?] The Partridge, when full-grown, "weighs thirteen ounces, 
and the Ptarmigan, fixteen. ;vi r
