Bartlett Giamatti, then President of the National League, when I served as Physicist to the National League. Hence the book has no equations in the body of the text and but a few in the end notes.

This paper contains the results of measurements of bat vibrational frequencies by Professor Uwe Hansen in an appendix. As a consequence of the renormalization of the calculations to fit Hansen's, the times in Figs. 5 and 6 should be reduced by a factor of about 0.8.
