THE OCCURRENCE OF BARIUM IN THE CORNEAL SURFACE OF THE BARKING DEER, MUNTIACUS MUNTJAK (ZIMMERMAN) AS REVEALED BY ENERGY-DISPERSIVE X-RAY-MICROANALYSIS

Energy dispersive X-ray micro-analysis with simultaneous visual displa y by secondary electron emission mode of scanning electron microscopy reveals the occurrence of barium, in addition to silicon, phosphorus, sulphur, potassium and calcium in the corneal surface of the barking d eer, Muntiacus muntjak. The lenticular surface on the other hand shows the presence of aluminium silicon, phosphorus and sulphur but no bari um. Quantitative data obtained by using the ZAF-4/FLS programme (Link) shows that the relative percentage of barium is the highest of all th e elements detected in the cornea, whereas in the lens-surface, sulphu r constitutes the maximum percentage.
