Abstract
IN this little pamphlet the author attempts to disprove the existence of the “Canal of Petit.” He describes the Zonula itself as a band, triangular in section, which passing over from the summits of the ciliary processes to the lens capsule embraces the edge of the lens, and becomes attached to both its anterior and posterior surfaces. The fine fibres of which the band itself is composed are in the anterior portion somewhat stouter, and joined together by an imbedding substance so as to form a membrane which offers abundant resistance to post-mortem changes. In the posterior portion the fibres are tender, free from any connecting substance, and very speedily break up after death; they thus readily give way before insufflation or injection, and the cavity or canal thus artificially produced in the posterior portion of the zonula is that which is known to anatomists as the canal of Petit.
