202                     The Anatomical Defcription
are fifllicd, if I may fo fay, from the groffeff and moft impure portion
of the
Blood which they retain, to the end that the part defigned for the Formati-
on and Nourifiment of the Fa'tus may be finer and purer. This ConjeEture
which for the  reafons may have fome probability, has been likewife confir-
med by the particularity that we have remarked in our Subjea ; where this
black Purf& not appearing, we found the Choroides a great deal thicker
than
ordinary; as if the whole dregs of the blood,which in the Eyes of other Birds
fhould be retained in the Choroides and black Purfe, had here been colleaed
in-
to the Chorcides alone.
