This will enable in ven tors ot small means io obtain patents for three years, to test their inventions, when, if they do not pay them well, they can drop the protection of the patent, by not paying the installment. More patents will now be taken out in Eng land, and one patent will embrace the United Kingdoms ot England, Scotland, and Ireland, together with the islands of Guernsey, Sark, and Man, and the noted town of Berwick-np on-Tweed.
