" When the trunk is opened lengthways, a fait- 
“ ifh liquor flows out of it, fo vifcid as to hang 
“ down an inch ; the whole trunk of the flem is 
** hollow, its outward coriaceous membrane is more 
** than a line thick, and forms a ftrong covering 
“ to it: between this and another thinner membrane 
“ of the pinnated part of the trunk are innumerable 
“ little yellowifh eggs, floating in a whitifh liquor, 
“ about the flze of a white poppy feed ; thefe are 
** befl: feen, when the trunk is cut acrofs : This 
“ thin membrane lines the whole inflde of the 
“ trunk, in which we obferve nothing but a 
“ kind of yellowifh bone, which takes up three 
“ parts of the cavity. 
<f This bone in fome of thefe animals is above 
“ 2JL inches long and about half a line thick j in 
the middle part of it, it is four fquare or quad- 
<( rangular ; towards each end of it, it grows round 
tc and very taper r that end is fmalleft, which is 
“ neareft the top of the pinnated trunk. The 
<c whole bone is covered with a yellowifh clear 
“ fkin, which at each end changes into a liga— 
(e ment; one of which is inferted in the top of 
“ the pinnated trunk, the other in the top of the 
“ naked trunk ; by the help of this upper liga- 
“ ment, the end of this little bone is either con- 
(C trailed into a very narrow arch, or dif- 
<f poled into a flraight line, according to the 
“ motion of the trunk. 
“ The fins likewife are compofed of two fkins ; 
lt the outward one ftrong and leathery and covered 
“ over with an infinite number of crimfon ftreaks,
