Textbook of normal histology: including an account of the development of the tissues and of the organs . further in those portions most removed from the perichondriumthe ground-substance appears granular; this feature is intensifiedwhen a deposition of calcareous matter takes place, which not infre-quently happens in old subjects. Elastic cartilage is distinguished by the presence of elasticfibres within the intercellular substance. The typical hyaline matrix is confined to areas oflimited extent immedi-ately surrounding thecell-nests, while the in-tervening matrix ispenetrated by net-works of elasticfibres extending in alldirections. The cellswithin the lacunae, inthe midst of the hy-aline areas, resembleclosely the usual ele-ments of hyaline car-tilage. Elastic cartilagehas a much less generaldistribution than thehyaline variety, occur-ring principally in thecartilages of the ex-ternal ear, part of theEustachian tube, epi-glottis, arytenoid cartilages, cartilages of Wrisberg and of tissue presents an opaque, yellowish tinge in contrast to the Fig Elastic cartilage from the epi-glottis : c, cartilage-cells sur-rounded by a very limited area ofhyaline matrix (K); the remainingpart of the intercellular substanceis penetrated by net-works ofelastic fibres (e), cross-sections ofwhich appear as minute points. Fibro-cartilage from theknee-joint: c, cartilage-cells surrounded by verylimited areas of hyalinematrix (h); the space be-tween these areas is occu-pied by the fibrous tissue. THE CONNECTIVE TISSUES. *j opalescent, bluish tint of the hyaline variety. It is covered by aperichondrium of the usual description. Fibro-cartilage, as implied by its name, is largely composed ofinterlacing bundles of fibrous connective tissue, embedded inwhich the round or oval cartilage-cells lie, singly or in groups,immediately surrounded by a narrow zone of hyaline number of the cells and the proportion of fibrous tissue presentdiffer i
