„In the eys of fifhes he obferved that the procefius ciliaris 

 „is no faftened to the joining of the cornea and fclerotis , as in 

 , ; all other animals he difTecled, fo as to.hinder the aqueous humor 

 ,,to go any farther backwards; for he confiantly obferved, that the 

 ,,aqueous humor may move a good vvay backwards in fbme, and 

 „in others almoft as far as the optic nerve. In all the fifh he 

 „examined, hefound a membrane, whichcovered the tunica cornea 

 „fb as to prevent any water coming to-kj and this anfwers the mem-

De liene ita de Partibus III. 7. Quibus, inquit, parum excre-

 tae gratia duntaxat eft. Fellis felleaeque veficae varietatem enarrat 

 H. A. II. 1 6. et alibi ; quae loca in fingulis fpeciebus adpofui. Renes 

 cum vefica oviparis avibus et pifcibus effe negat H. A. II. 1 6. idem 

 repetit de Partibus III. 9. cum quadam tamen avium exceptione. 

 De vefica urinaria ibidem cap. %. quae, inquit, animalia pulmone 

 fanguineo carent, fed fungofum feu veficularem (aoptyov) habent, 

 et parum bibunt , aut omnino aquam non potus fed cibi caufa affu- 

 riiunt, velut infecta et pifces , aut plumis, fquamis aut cortice te- 

 guntur, ea omnia vefica carent, quoniam parum humoris affumunt 

 et pars liquida excrementorum iri tegumentum convertitur. Verum 

 iterum Ariftoteks hic a veritate aberravit; omnibus enim pifcibus
