Human anatomy, including structure and development and practical considerations . Adult crystalline lens, showing; lens-stars;surface; radiating lines of jiincturc meet at cent ; B, posterior4. {Arnold.) THE XlTRKOUS BODY. 1473 passage of nutritive fluid. The fibres are so arranged tliat their ends terminate alongdefinite radiating striie, or Icns-siars, which in the young lens are three in numberon each surface. In the adult lens additional rays increase the numljer to from six tonine, the striie being less distinct but distinguishable with the ophthalmoscope. Thelens-fibres which come from the pole of one surface of the lens terminate at the end ofone of the radial stride in the other, and conversely; the intervening fibres take upintermediate positions. In adult life the lens-tibres become more condensed, the lensloses its clear appearance, and assumes a yellowish tint. This change affects thenucleus first and the periphery later, coincidently the lens becoming less elastic asthe result of its loss of water. Practical Considerations.—The lens may be congenital
