o the back like a V, the interstices of which are
also filled up with the aforesaid membrane. This last piece, in flight,
falls down almost to the ankles, where the two claspers lapping under
each leg within-side, hold it very fast; and then also the short apron
is drawn up by-the strength of the ribs in it, between the thighs
forward, and covers the pudenda and groin as far as the rim of the
belly. The whole arms are covered also from the shoulders to the wrist
with the same delicate membrane, fastened to ribs of proportionable
dimensions, and jointed to a cartilage on the outside in the same manner
as on the legs.
It is very surprising to feel the difference of these ribs when open and
when closed; for, closed, they are as pliable as the finest whalebone,
or more so, but when extended, are as strong and stiff as a bone. They
are tapering from the roots, and are broader or narrower as best suits
the places they occupy, and the stress they are put to, up to their
points, which are almost as small as a hair. The membrane between them
is the most elastic thing I ever met with, occupying no more space, when
the ribs are closed, than just from rib to rib, as flat and smooth
as possible; but when extended in some postures, will dilate itself
surprisingly. This will be better comprehend by the plates, where you
will see several figures of glumms and gawrys in different attitudes,
than can be expressed by words.
As soon as my wife had expanded the whole graundee, being upon plain
ground, she stooped forward, moving with a heavy wriggling motion at
first, which put me into some pain for her; but after a few strokes,
beginning to rise a little, she cut through the air like lightning, and
was soon over the edge of the rock and out of my sight.
It is the most amazing thing in the world to observe the large expansion
of this graundee when open; and when closed (as it all is in a moment
upon the party's descent) to see it sit so close and compact to the
body, as no tailor can come up to it; and then the several ribs lie so
justly disposed in the several parts, that instead of being, as one
would imagine, a disadvantage to the shape, they make the body and limbs
look extremely elegant; and by the different adjustment of their lines
on the body and limbs, the whole, to my fancy, somewhat resembles the
dress of the old Roman warriors in their buskins; and, to appearance,
seems much more noble than any fictitious garb I ever saw, o
