註釋Ms. transcription of depositions given at the Philadelphia Hotel in Jersey City, N.J. between Aug. 27-29, 1851, by William Ballard and Stephen Hale in the patent infringement case--known as the Great India Rubber Case of 1852--brought by Charles Goodyear against Horace H. Day in the United States Circuit Court for the District of New Jersey. William Ballard and Stephen Hale, witnesses for the defendant Day, are questioned by counsel George A. Vroom, and cross-examined by the complainant's counsel, L.W. Goddard before Samuel Cassidy, commissioner and examiner for the Court. After experimenting most of his life, trying to make natural rubber useable with materials such as turpentine, Goodyear got the idea of adding sulphur from Nathaniel Hayward, who had also worked extensively with rubber at the Eagle India Rubber Company which he started in 1836 in Easton, Mass., and soon relocated to Woburn. In 1838, Hayward sold the company to Goodyear, and assigned him his patent for brushing sheets of rubber with sulphur and exposing them to sunlight. After years of infringing on Goodyear's patent, and manufacturing rubber goods without a license, Day was sued by Goodyear and his licensees, the Goodyear Shoe Association.
