CHAP. 8. (7.)—THE BIRDS CALLED SANGUALIS AND IMMUSULUS.
There has been considerable argument among the Roman
augurs about the birds known as the "sangualis" and the
"immusulus." Some persons are of opinion that the immusulus is the young of the vulture, and the sangualis that of
the ossifrage. Massurius says, [Note] that the sangualis is the same
as the ossifrage, and that the immusulus is the young of the
eagle, before the tail begins to turn white. Some persons
have asserted that these birds have not been seen at Rome
since the time of the augur Mucius; for my part, I think it
much more likely, that, amid that general heedlessness as to
all knowledge, which has of late prevailed, no notice has been
taken of them.
