Thus we see that the death-rates range, in round numbers, from 13 to 33 per thousand per annum, but in the great majority of districts lie nearer the lower limit than the upper ; that the death-rates in some 60 per cent. of the districts lie within the narrow limits 155 to 18-5, the rates being most frequent near 17 per thousand, and so forth.
