Abstract
REQUIRING recently the square roots of the numbers from 1 to 100 to ten figures, or one more place of decimals than is given in Barlow, I was led to the discovery that his last figure for numbers above 1250 is not to be depended upon for its accuracy. It is true that De Morgan, in issuing a reprint of Barlow's Tables in 1839, admitted that his method of checking Barlow's entries by differencing left “remaining a possibility of any of the last figures being a unit wrong in the columns of square and cube roots”.
