Second, the gelatinoids, which are represented by the ossein of bones, which can be made into glue, and the collogen of tendons.
This ossein, which forms on an average from 25 to 30 per cent of the weight of bones, is extremely rich in nitrogen, containing over 18 per cent.
The earthy matter is composed chiefly of calcium phosphate, about 58 per cent. of the weight of the bone, calcium carbonate about 7 per cent., calcium fluoride and magnesium phosphate from 1 to 2 per cent. each and sodium chloride less than 1 per cent.; they confer on bone its hardness and rigidity, while the animal matter (ossein) determines its tenacity.
_Gelatinoids_, constituents of connective tissue which yield gelatin and allied substances, _e. g._, collagen of tendon; ossein of bone.
