RESUMEN

The chemical and crystalline composition of the mineral deposited in ossified arterial and lung tissues of cows affected by enteque seco (enteque ossificans) has been investigated. The arterial calcification precedes that of lung. The latter was observed only in animals with a calcification of the aorta above 150 mumoles Ca per gram of wet tissue. The mineral deposited in arterial and lung tissues appeared to be a poorly crystallized apatite; following incineration the diffraction patterns of carbonate apatite and magnesium whitlockite, respectively, were found.
