794 .Mr. brown’s Defer iption of 
that the lower pinions are kept down by the mufcles on 
the anterior, by thofe on the pofterior and inferior part 
of the fcapula ; I fay, the effe£t of the action of thefe two 
mufcles is, to pull the pinions upward, and at a greater 
diftance from one another, or in other words to expand 
thd wing; for the joint does not allow of any motion up- 
ward, and if it did, it would not in the leaf! influence the 
fize of it. 
The other mufcles that lie on the external, internal, 
and inferior parts of the fcapula, together with feveral 
fmall ones that run backward : thefe, I fay, alfo ferve to 
move the wing backward and forward. This fcapula 
and wing, with all its apparatus of mufcles, can be eafily 
divided, except at the fuperior part, from the mufcles 
that form the fore part of the body of the fifh, being 
only connected by a cellular medium. 
The globe of the eye is large in proportion to the ani- 
mal; the pupil large too, and nearly, if not altogether, 
circular. ' The cornea is lefs tranfparent than in the ge- 
nerality of fifties; the fore part of the globe is a good 
deal flatted, as if a fegment or portion had been cut off, 
for fo fmall a part of the aqueous humour is contained 
between the cornea and iris, which is of a filver colour, 
that they are nearly in contact.
