almost any person at all acquainted with the subject would have readily accomplished in halt an liour: for here are neither delicate ex_perimental. investigation,. . requiring, time to .mature anti., re petition to conhrm, nor mtrmate mechanmal constructmn, requn-mg the cmflidential aid of others to bring to perfection. We consider that the different periods allowed by the present practice to different patentees for the enrolment of their specifications, is one of the principal defects of the system: and Mr. Rotch, from the experience that he has ]tad in that branch, and to which he recently said to a committee of tile House of Commons, that he had directed particular attention, cannot but be aware, that if A, for instance, • takes out a patent tbr an improvement m the steam ene,O. i ne, and" takes twelve months to enrol the same, and B s~bsequently takes out a patent, also for improvements in tile steam engine, and obtains but two, four, or six months to enrol his specification, there is nothinz to nre. vent A from inspecting B's specification in the enrolment ot~ice,'and adopting it as his own; as hewas not required to give any description of his invention at tile time he obtained the patent. It is not a little singular, that Benjamin Rotch, Esq. of Bath, on the 1 lth of May, ~816, took out a patent for " a flexible elastic horse sime," consisting of '~ two or more pieces of iron, steel or any other. metal, attached either by the nails which fasten tile shoe to the foot, or by rivets expressly foe the purpose, or sometimes by both, or otherwise fastened or applied to one or more pieces ofleather~ hat, Indian r!ebber, m" any o/her ttexib.le substance. '~ The application to this circumstance ol the fol!owmg extract from the evidence of Benjamb~ Rotch, before a committee of the House of Commons, on the patent law, will readily occtlr to the r e a d e r : ~ " L o o k , (says he,) at the danger of allowing patents for improvemerits, even with tire consent of tile party, oa articles that are already patented; it would continue a patent ad infinilum: improve. ment on improvement, just as their fourteen ,gears are expired; because it is what patentees come to me constan{ly to know, if they cannot, tbr some little improvement, obtain a patent on their own patent, wMch would be an extension of the term to twenty-eightycars instead of fourteen, and thereby shut the public out o{~ the benefit they are to have at the end of fourteen years." Now it would be very interesting to know whether Benjamin Rotch, of Bath, in 1816, be any relation, or at all connected with Benjamin Rotch, of London~ in 1830.

These ~ ~ strengthening plates are secured to ~/~.~/~'~.///~j/~_ tlae casting and lining by rivets or .~&~x~, \~ ~-. . . . --'- bolts, and the space between the linings is enclosed at the top, air tight; and by that means much buoyancy is o;~tained from it in cases of danger when the boat fills with water, l'he deck of the vessel is also to be made of plate iron, which is to be secured and strengthened in a maimer precisely similar. To prevent the mast from being injured by the edges of the iron plates,a piece of iron tube, of dimensions to correspond with the diameter of the lower end of the mast~ is introduced through, and firmly secured to, the deck. The top rail of the bulwarks is made of iron tubing connected tosgiether by passing their ends into sockets, and connected with the des of the vessel by iron plates bent in the form of the surface of a pantile roof, to give them strength.

UNDI~lt the head of New Process of.Distillation, at page 4 t 7 of our last volum% we gave some account of the invention for which a patent was granted to Mr. Robert Hicks of London, by which the alto, holic vapour arising from fermented doug, h in the process of baking, was condensed and collected. We havenow procured a drawing of the apparatus employed, which will serve to render the mode of procedure perfectly intelligible This drawing, with the accoml)anvin~ description, we have copied fi'om the Register of Arts, for February last. It will be readily conceived thatthe numerous small fissures in an ordinar Y oven of brickwork,' arisin~, J from imnerfect fittinzs and other Q o causes, render the material unfit tbr the preservation of the vapours given off: Mr. Hicks accordingly employs an oven made' of iron in lieu of brick; but the bottom of the oven on the interior side is lined with a pavement of bricks,'on which the loaves are placed as usual; a fire is made underneath the oven, at a proper distance, and brick flues from thence are so arranged that the heated air shall envelope every part of the exterior of the oven, to diffuse tile heat in the interior of ~t as uniformly as is practicable. The door of the oven is made to fit the fi'ame accurately, by grinding their surfaces, or by luting when set to work, and these parts are brought into firm contact by a cross bat" and screw in the usual manner of fastening the mouths of retorts. In tile drawing accompanying the specification, two modifications of the apparatus are exhibited. - The tirst is an oblong oven five feet
