Leg, was vifibly lefs red than the others. I have 
found the little Bones of the Larynx and of the 
Apophyfes tinged of a fine Red, though thefe are as 
fmall as a Thread in young Pigeons. The Rings of 
the Trachea-, which are intirely cartilaginous, had 
not taken the lead Tinge 5 but the Ring neared the 
Divifion of the Trachea was red in thefe Pigeons; 
and even the Fird Ring of each Branch of the Bifur-

coloured Liquor that was contained in Vedels, as in 
Parts injefled; but that it Was only a fort of Facula

the Pvoot to the fmall Villi of the inner Membranes 
of the Organs of Digedion, that is the Source of all 
the Didempers with which thefe Creatures appeared 
to be feized, while I fed them with the Madder. 
Their Crop efpecially was relaxed and dabby, as if 
it had been macerated feveral Months in Water; it 
was eafily torn, and its inner or villofe Membrane
