natsk djinkat ka = 30 men.
400.

dak'on djinkat ka = 40 men.
This scale contains a strange commingling of decimal and vigesimal counting.

The words for 20, 100, and 200 are clear evidence of vigesimal, while 30 to 90, and the remaining hundreds, are equally unmistakable proof of decimal, numeration.

The word _ka_, man, seems to mean either 10 or 20; a most unusual occurrence.

The fact that a number system is partly decimal and partly vigesimal is found to be of such frequent occurrence that this point in the Tlingit scale need excite no special wonder.
