Excerpt from Worm Gearing
A second edition Of this book having been called for, the opportunity is afforded for making corrections of a few typographical errors, which appeared in the first edition. Part of Chapter IX has been rewritten, and three short appendices added to bring the text abreast Of the writer's most recent investigations. It is hoped that the value of the book is thereby considerably enhanced.
