Human anatomy, including structure and development and practical considerations . rs ciliaris retinae in the vicinity of the ora serrata. The investigationsof Retzius, Salzmann and others indicate that some fibres arise also from the mem-brana limitans interna of the pars optica retina;, whilst others pass into and endwithin the vitreous body. The greater number of the fibres pass forward chiefly inthe depressions between the ciliary processes, and along the sides of the latter, closelyapplied to the surface ; they then proceed outward across the circumlental space tobe attached to the capsule of the lens. Some of the fibres are inserted anterior tothe equator, others posterior to the equator, and some directly into the lens inserted anteriorly arise behind and chiefly from the valleys between the ciliaryprocesses, whilst those inserted back of the equator come from the ciliary processesin front. As they diverge to gain their insertion in the lens-capsule, the crossingfibres enclose an annular space, triangular in section, whose base is directed toward.

The fibres are so closely interlaced that it is possible to inject airbetween them and so produce a beaded ring surrounding the lens. This appearancewas long inter]M-eted as demonstrating the presence of a delicate channel, the canalof J\iit, encircling the lens. The existence of a definite channel, however, is nolonger accepted, the space capal^le of inflation being jjart of the larger circumlentalspace, which is filletl with lluid and comnuuiicates, by means of fine clefts, witli theposterior chamber. In addition to the chief zonular libres, accessory bands occur, some of whichpass from the ciliary processes to the long zonular fibres, whilst others extend frompoint to point on the ciliary processes.
