These volumes contain all the scientific papers by Sir Geoffrey Taylor that he and I have been able to locate, apart from some that duplicate work herein, and apart from a number of minor unpublished notes thought to be no longer of interest. The papers have been prepared for the present volumes with as little change of their original form as possible. Printing errors and small mathematical slips in the first publication have been rectified without comment, but any substantial change in the text as originally published has been disclosed in a footnote.
