Galton did not develop a formula for calculating precise correlations. He instead used visual methods such as scatterplots and regression lines to examine the relationships between variables. He also observed the phenomenon of regression to the mean, which is the tendency for extreme scores on one variable to be closer to the average on a second variable when the two variables are correlated.
