   • 1829, University of Groningen, Annales Academiae groninganae, Commentatio de diverticulus intestinorum, page 69:

     Baillie exemplum praebuit diverticuli coniuncti cum vitiis a niſu formativo abnormi productis: illuc ſc. invenit in foetu, cui aderat omnium thoracis et abdominis viscerum ſitus inverſus, una cum partitione lienis in quinque lobos, uti in Cetaceis ſolet.

     Baillie provided an example of a diverticulum connected with defects extended by an abnormal formative impulse. To that point naturally it is found in a foetus, to whom an inverted position of all the internal organs of the abdomen and thorax is present, together with a separation of the spleen into five lobes, as is usual in cetaceans.

Second declension.
