which feed upon fiiell fifli many Birds of the Dacfc 
kind, which (as I faid,) all feed partly at leaft upon 
fliell-fifh ("as Monfieur Graindorge found the Mccreufe 
alfo to do,) have a delicate and well taftedflefli, as for 
example, the common Mallard and Teal: whereas the 
fleftiofail thofe kinds that feed wholly or chiefly upon 
fifli properly fo called, is of a Rank, ferine and pifcofe 
tafl:, as for example, that of the Soland Goofe, the En- 
glifh Puffin^ and thofe of the tridadylous kind, fothat 
only the young ones of thofe kinds are admitted to our 
Table. loblervedin this Bird, andinfome others of the 
Sea-Ducks that are much under water, that they want 
that VeflTel or ^mpullaSitmtQ in the very Angle of the 
divarication of the Wind- pipe, which for want of a bet- 
ter and fitter name, we are wont to call the Labyrmth oE 
the Trachea i which though being common alfo to the 
Colymbi, which of all Birds dive moft, and continue long- 
eft under water, we may very probably from tlienee con- 
clude, that the X^^^r^'w^/? doth not fervethem for a Re- 
fervatory 6f ^/r, to enable them to continue the longer 
under water, as I fometimes conjectured i but for the in- 
tending and modulating of the Voice,feeing in the Plafli- 
Duck, the females want it ; but I am fomewhat to feek 
about the ufe of this VefTel, and I think it were worth the 
while, to examine what forts of Birds have it, what want 
it; whether the Males only, or in fome the females alfo. 
I obferved it in tho^ Mergus cirratus longirojter major ot 
the Dun-divary and that very large, and extended by 
very flrong bones, and yet I thought my felf to have fuf- 
ficient reafon to Judge that bird to be the female of the 
Merganjer: but I dare not be confident that it is a fe- 
male becaufe of this Labyrinth. 
And now becaufe I am writing of Birds,I propofe it to 
yourCo-nfideration, whether that fort of Bird mentioned 
by the learned Dr. Flot^ to be often heard in Wood'-
