No evidence of metachromasia has been observed so far by us. Another striking difference between ageing of arterial and dermal elastic tissue exists in the calcium content of the two. As has already been indicated the ageing of arterial elastic tissue may be measured in terms of the amount of calcium it contains. Juvenile arterial elastic tissue is free of calcium; with age it progressively takes up calcium, as much as 18 per cent of the dry weight of the.
