The movements of which these articulations may be the seat. 7. Their methodical classification. 8. Their nomenclature. Aeticular Surfaces.—These surfaces have the common character of being destitute of asperities, so that they can glide with the greatest facility on each other. They are designated, according to their form, by the names of facets, heads, condyles, cotyles, ylenes, pulleys, etc. There is no need to revert to their general description, as they have already been sufficiently studied in the osteo- logy ; so we will confine ourselves to repeating that they are found at the extremities of long bones, on the faces of short bones, and on the angles of wide bones. We may mention, also, that they are often excavated by one or several depressions named synovial fossiB, or hollows for the insertion of ligaments. The first are a sort of natural reservoirs which receive the unctuous fluid secreted by the interarticular serous membranes ; the second give attachment to interosseous ligaments. Cartilages op Incrustation.—This designation is given to the layers of cartilaginous matter which, as it were, varnish the articular surfaces they adhere to by their inner face ; their free surface is distinguished by a remarkable polish and brilliancy. Thicker towards the centre than at the circumference when they cover bony eminences, these carti- lages show an inverse disposition when they line cavities. They are elastic, of a pearly whiteness, and resisting—though they are soft enough to be cut by a sharp instrument ; in a word, they possess all the physical characteristics of the primary cartilage of bones. They appear to be formed of parall
