The Dobchick, Fig. 2. is in the col- 
lection of Lady Dutchefs Dowager of Port- 
land, who obliged me with a light of it. 
Her Grace informed me, that it was taken 
on the Lake of Geneva, where they take 
off the white feathered fkins on the under 
fide of the Birds, and prepare them as 
leather is prepared, with the feathers on 
them* then they are joined, and made up 
into tippets, muffs, &c. for the Ladies. 
Another Bird of the felf-fame fpecies, 
brought from Geneva together with this, 
is preferved in the Britilh Mufeum. This 
feems to be the fame with the Greater 
Loon or Arsfoot, ( Colymbus Major , Al- 
drov .) See Willughby, P. 339. Tab. lxi. 
I think I bought this very fpecies of Dob- 
chick or Loon dead at a Poulterer’s in 
London, in the hard winter, 1739 and 
1740. I have a drawing of it as big as life, 
which agrees with that of Geneva in every 
refpedt, except that the upper iide is of a 
darker alh -colour. 
The Round -crefted Duck, Fig. 3. is 
from Penfylvania. I received it, with other 
Birds, from my obliging friend Mr. Wil- 
liam Bartram, of that Colony. In his 
Letter of December 1759* accompanying 
thefe Birds, he informs me, that they are 
all Birds of Paffage ; that they arrive in 
Penfylvania in November from the north, 
and continue till March, when they return 
again. Mr. Bartram fays, that many ani- 
mals, which abounded formerly in the 
fettled parts, are now no more to be found, 
but retire to the unfettled borders of the 
rovince ; and that lbme Birds, never 
nown to the early lettlers, now appear 
in great numbers, and much annoy their 
corn-fields and plantations. Catelby has- 
figured this Duck of its natural iize, in 
his Hiftory of Carolina, Vol. I. Page 94, 
He rightly obfcrves, that it is not itriCtiy 
of the Duck kind, but of the Mergus, 
deferibed by Willughby. See various Ipe-
