PREFACE.

THE "Patents, Designs and Trade Marks Act, 1883," has made many changes in the law of great importance, and most of the alterations in the Patent Law will probably be found to be beneficial to inventors, though a great deal will depend upon the spirit in which the Act is carried into effect.

The reduction of the Government fees to £4 for the first four years of the Patent, instead of £25 for the first three years, will be of great advantage to Inventors. I regret, however, that the fees required to keep the Patent in force after the fourth year have not been very much reduced, or abolished altogether, or perhaps rather altered to a special income tax on the profits made from the successful Inventions.

4, MIDDLE TEMPLE LANE,

October, 1883.

JAMES J. ASTON.
