the improvement which was the subject of the patent, whilst employed in their workshop. Mentioned on the trial, Bloxam v. Elsee, 1825.

Note.-Messrs. Barker and Harris had a patent, in 1821, for improvements in the method of cleaning furs and wools used in the manufacture of hats, from kemps and hairs; it is stated Barber in the above report, by mistake.

Savory against Price. An action for infringement of Savory's Patent of 1815, for a method of making a neutral salt, or powder, possessing all the properties of the medicinal spring at Seidlitz, under the name of Seidlitz Powder. Tried in the Court of King's Bench 17th December 1823, before Chief Justice Abbott. The Patentee was nonsuited.

The specification gave three distinct recipes for preparing the ingredients, and then directed two scruples of each of the three ingredients resulting from those recipes to be dissolved in half a pint of water, in order to produce the imitation of Seidlitz water. It was proved by following the directions given in the specification, the result was obtained, and that it was new and useful. It appeared that the three recipes were only common processes for preparing three well known substances, viz. Rochelle salts, carbonate of soda, and tartaric acid, which were sold in shops before the date of the patent; and those three substances being used as directed, constituted the Patent Seidlitz Powder; the specification did not give any name to the ingredients resulting from the three recipes; but gave those recipes without comment, as if they were part of the method of making the Seidlitz powder.

Lord Chief Justice Abbott: " It is the duty of a patentee to specify the plainest and most easy way of producing that for which the patent is granted, and to make the public acquainted with the mode which he himself adopts. By reading this specification, we are led to suppose a laborious process necessary to the production of the ingredients, when in fact we might go to any chemist's shop and buy the same things ready made. The public are misled by this specification, which tends to make people believe that an elaborate process is essential to the invention; it cannot be supported." The plaintiff was accordingly nonsuited.

Morton against Barclay and others. An action in Scotland, for infringement of Morton's Patent of 1818, for a method of dragging Ships out of water on dry land. Tried in the Jury Court at Edinburgh, 15 March 1824, before the Lord Chief Commissioner, Lord Gillies, and Lord Mitmilly. Verdict for the Patentee. The invention is a substitute for a dry dock for repairing ships. It consists of a horizontal frame or very low carriage with rollers, or small wheels adapted to run upon an inclined plane or slip, such as is commonly used for building ships;

also a strong crane work to drag that carriage up the plane, by a chain, when a ship is placed upon the carriage, which can run down the inclined plane so far under water that the ship can be floated over it. A beam which extends along the middle of the carriage, supports blocks on which the keel of the ship is to rest; and there are several cross beams, on which other blocks are fitted in grooves so as to slide to or from the middle beam, in order to adapt them to block up under the bottom of the vessel, and keep her upright on the carriage: these sliding blocks can be drawn into their places under the bottom, as the vessel settles down on the carriage, after the keel is come to rest on the blocks.

The pursuer erected several such patent slips at various places in England and Scotland under his patents, and the defenders made one near Glasgow in infringement thereof; whereupon the pursuer raised an action in the Court of Session; the defenders, in answer, denied any infringement, alleging that their machine was different from the pursuer's. The question was remitted to the Jury Court, where defenders did not appear, thereby admitting the infringement. The merit and utility of the invention was proved by the testimonies of several naval officers, engineers, and ship builder; several of them taken in writing in England on commission.

The Lord Chief Commissioner made some observations as to the law of Scotland in cases of this nature, and that he thought it would be a desideratum to have the point settled. The pursuer's advocate submitted, that since the Union, the practice in regard to patents was the same in Scotland as in England. The Lord Chief Commissioner said, that as the defenders did not appear, the court must suppose their cause indefensible; he had never seen a case before any court more fully made out than the pursuer's. The practice in England rendered it necessary or the pursuer to make out, 1st. That the invention was original, and was made by the patentee himself; 2nd. That his patent right had been invaded. In this case it had been proved that the invention was original; that it was useful, and preferable to dry docks; that it would be of the utmost utility in places where there was not a rise and fall of tide; that the shipwrights working in the dry, may work longer days than in a dock, and can more conveniently use long planks. With regard to the law in questions of this nature, he would say nothing; he believed that this was the first case which had been brought to trial upon similar issues. No amount of actual damage had been proved, and it was only a question of the right. The jury found a verdict for the pursuer, with one shilling damages and costs.-Printed Notes of the Trial.

Bloxam and another, assignees of H. and S. Fourdrinier, bankrupts, against Elsee. An action for Infringement of Gamble's

Patents of 1801 and 1803, for a Machine for making Paper. Tried in the King's Bench, before Chief Justice Abbott, 18th Jan. 1825. Verdict for the Patentees.

The machine acts by the continuous motion of an endless web of woven wire cloth, circulating over horizontal rollers, and forming a moving horizontal plane, on which the pulp is spread at one end, and during the motion thereof, as the pulp advanced to the other end, it is formed into a tissue of paper, which is taken off in a continuous sheet at the other end of the moving plane. (To be continued).
