most other tissues in consisting chiefly of inorganic salts. The chief of
these is calcium phosphate, with which much smaller quantities
of calcium carbonate, and magnesium phosphate and carbonate
occur. These inorganic salts can be removed by immersion of the
bone in weak hydrochloric acid, and a flexible network of connecting
tissue, Haversian vessels, bone corpuscles, and their processes
remains. This is decalcified bone alluded to above.
