surement was made law, had arrived at the true form of a perfect ship, and that, if all ships were built on the principles which governed their decision, every vessel would pay its fair quota of dues, and no injustice would be done. By a perfect ship, I mean one which, as an investment, if no peculiar influences operated, a shipowner would prefer as being the most profitable, viz.-the vessel which, with the same rate per cent. depreciation for wear and tear as other vessels, would, from its sailing qualities, command the highest freight, and, in given time, make the greatest number of voyages, and from its capacity, carry the largest cargoes; the three must be taken together. Vessels are the more perfect the nearer they approach this standard; nevertheless intentional deviations occur in two directions. The first is in regard to capacity. If we increase the dimensions in those parts of a ship where the dimensions will not tell in the estimate for dues, a saving is effected to the shipowner; the possibility of doing this being known to him, he expects and requires his vessel to carry twenty per cent more than her registered tonnage; and, like other manufacturers, the shipbuilder works up to the requirements and expectations of his market. By variation from the perfect form upon which I have assumed the present mode of measurement to be based, the capacity for cargo may be increased without increasing the dimensions which regulate the tonnage dues, but this can only be done at the sacrifice of the other element of perfection speed. The second deviation is in the opposite direction. With the intention of increasing the sailing qualities, such a form is frequently adopted as necessarily reduces the space for cargo; hence some vessels pay more dues than fairly rendered liable to by the cargo. They do not carry what their register states. By the alteration of the law which is proposed, so that the actual capacity shall be taken for the calculation of the dues, the encouragement at present held out to the shipbuilder to construct illformed vessels would be removed, as he would cease to gain anything by departing from the best model.

YARMOUTH (Great).-A special general meeting of the members was held on Monday fortnight, to consider a report from the Accomodation Committee, which had been appointed to enter into negociation with the directors of the Yarmouth Club-house. It appeared that by the trust deed of the company there was no power to effect a sale. Under these circumstances, and feeling the necessity for enlarged premises, Mr. James Barber, the secretary, suggested that the general committee should be empowered to raise a fund for the purpose of providing a building adequate to the daily increasing demands of the society. This proposal was cordially acquiesced in, and the committee were authorised to establish a fund by 17. shares, or otherwise.


REWARDS TO MEN OF GENIUS.-The President of the United States of America, in his message delivered to Congress, on the 6th inst. says, "I commend to your favourable consideration the men of genius of our country, who, by their inventions and discoveries in science and art, have contributed largely to the improvements of the age, without, in many instances, securing for themselves anything like an adequate reward.

ERRATUM, Page 27.-In the Second Edition of the Abstract of Dr. Playfair's lecture on Food, an important typographical error has been corrected. The last line of the Prison Diet, described as "solitary confinement," should be struck out, as it was a reprint of the line of diet for classes 4, 8 and 7. These classes have 229 oz. per week of food for female prisoners, but for males, 271 oz.



MEETINGS FOR THE ENSUING WEEK. Royal Inst., 3.-Professor Faraday, "On Voltaic Electricity."

The subject is of great importance, both to human life and property, numbers of vessels being annually lost entirely from their bad construction; they are unweatherly, and drift to leeward and ashore, when better modelled ships keep to sea. As an illustration of the increasing attention paid by merchants to the build of ships, I may mention that of two vessels lying in the same dock, and bound to the same port, one being reputed of good build, and therefore likely to prove a fast sailer (not having made a voyage, it was entirely a matter of opinion), had more goods offered at 51. per ton than she could take; the other having a different reputation, did not succeed in ob- THURS. taining a full cargo even at the low rate of 31. per ton. I have not gone into details, my object being to suggest rather than exhaust the subject. I shall be happy to SAT. hear of the Society investigating the matter thoroughly. The views of the principal shipbuilders, shipowners, merchants, Chambers of Commerce, and scientific men might be collected, and their opinions embodied in a representation from the Society of Arts to the government, and a speedy alteration in the law would, I trust, be the result.

and aquatint processes of engraving for broad effects, and copper-plate or line and chalk-engraving for works requiring a further degree of precision. These four processes are entirely distinct from wood-block engraving, "The names of most of those who are thus and cannot be used in combination with letter-press. In distinguished, are probably familiar to the world, the mezzotint the surface of a copper-plate was scratched and nothing is needed to remind men of the re-in such a manner as to produce upon it a rough face, putation they have so justly earned, or of their forming a uniform ground for retaining the printing-ink.

the copper was obtained by covering it with a ground which dried in reticulation. Upon this dilute aquafortis was poured, which eat into the surface of the plate wherever unprotected by the varnish, thus forming a means for retaining the printing-ink; and the lights are obtained by burnishing, as in the mezzotint. Line-engraving, however, is essentially distinct, and is directly the the print being cut in lines into the copper, more or less reverse of wood-block engraving, all the parts producing deeply, instead of being in relief, as in wood-blocks or surface printing. By this means delicacy of touch and

red, a third the yellow, &c. The power of producing graduated tints with ink and chalk combined, enabled Mr. Hulmandell to take the lead in the production of pictorial effects; and Mr. Owen Jones has carried this to a still higher point by graduating tints in ink only, by stippling on polished stones with the fine point of a camel-hair pencil, as illustrated by his work, "Flowers and their Kindred Thoughts." And this process, somewhat modified, is at present largely employed in the production of artistic effects.

precision of outline could be obtained better than by the mezzotint or aquatint process. A fourth process was, however, introduced about the same period, known as chalk engraving, and to this reference will be made hereafter. The peculiarity consisted in producing on the surface of the copper, by appropriate tools, a series of dots, giving the granulated effect of a chalk or crayon drawing on paper. Early in the present century it was discovered that steel could be employed with advantage by the line-engraver in place of copper. At this period came into notice Lithography, which was then discovered, by Sene- The next and most important improvements in the felder.

It is not to be denied, that at the time of its introduction the public greatly undervalued the rough freedom of lithography; and it was not till after Hulmandell had introduced a series of improvements in the processes employed that it was favourably received by artists. The first English artist who made use of lithography in England was the late William Nicholson, who sketched landscapes on stone with great facility. Mr. Samuel Prout and Mr. J. D. Harding were also among the earliest and most successful of those who adopted lithography. In portraiture lithography was early employed; and among those portrait painters who have themselves drawn upon stone, may be mentioned Messrs. Doyle, Eddis, Hayter, Linnell, and Sir William Ross, R.A. Lithography, from having hitherto been regarded as inferior to engraving, now came to be thought of as a rival to that art; but hitherto it has been unable to produce in black and white such effects as the mezzotints of Cousins and Lewis, or the line engravings of Doo and Robinson, Heath and Finden. The Portrait of Senefelder, in his work, is one of the first specimens of printing with a tint. The drawing with chalk was first printed, and on that impression the neutral tint was printed from another stone, the parts representing the high lights being left white; but the effect of the high lights was harsh and crude. This objection Mr. Hulmandell overcame by the introduction of a drawing material between ink and chalk, which, being applied to the hard edges of the liquid ink, carried the full tint by gradation into the white lights.

The early efforts of Senefelder in printing in colours gave but a faint idea of the richness and beauty of the productions of Mr. Owen Jones and other artists. Mr. Hulmandell was the first to develope the resources of colour printing, and the method he employed was to transfer the required outline to several stones, the first stone giving the outline and black parts, a second the

the aquatint process has been entirely superseded; and although the mezzotint and chalk processes have been combined, as illustrated by the works of Mr. Wagstaff, yet the production of works of importance in those branches has ceased. Line-engraving, too, although an independent art, has, for illustrative purposes, been set aside. Wood-engraving is again rising into importance, to be found hereafter in combination with lithography and colour-printing. Of the specimens now exhibited, those by Baxter serve to illustrate the efforts which have been made to give fresh life to the art of aquatint engraving, by combining it with the chalk process before described, so as to get detail and precision of drawing in the minuter parts, at the same time that chromatic effect is obtained by the combination of a series of tints printed from aquatint grounds. The specimens by Leighton Brothers are produced by another modification of the aquatint process, in combination with wood-blocks, and are surface printed; or by a combination of wood-blocks with tints printed from lithographic stones. The process employed by Messrs. Leighton, in order to obtain their aquatint metal blocks, is the electrotype from a copperplate, the surface of which has been prepared by the action of acid and the aquatint ground; thus, by a series of blocks in relief variable effects are obtained with any required boldness or delicacy of surface. The great point to be attained is precision of drawing by a combination of tints, at the same time that the lines or vanishing points of the tints are studiously lost. The specimens of Chromo-Lithography exhibited by Messrs. Brooks, Day, Hannhart, Leighton, Rowney, &c., depend for their perfection in the production of coloured pictures and objects, on getting rid entirely of positive lines, and dispensing with what is technically called the black stone' or printing with black ink. The artistic effects are produced by the increased number of stones and the use of half tints. Thus, by combining a higher artistic power with skill in manipulation, and a greater subdivision of colour, a gradation of tone and blending of parts is obtained,

patent right in inventions in the arts and manufactures, has usually been regarded in its origin, rights, and protection, as presenting so many difficulties that the branch of jurisprudence relating thereto has been termed the metaphysics of the law. But it may be doubted whether this property, either in respect of its origin or of the principles on which it is founded, presents any difficulties not common to other species of property.

"Jurists and metaphysicians have advanced various, and in some respects inconsistent, opinions on the origin and rights of property; some treating the conception of property as an original notion inherent in the mind, others as evolved from a previous sense of justice, its protection and distribution being regarded as matter of public policy to be provided for by the laws of each particular country, "The idea or conception of property is antecedent to any notion of law; it is not the law of the land which constitutes the basis of property; neither does natural justice constitute property; justice is a virtue which presupposes property, and respects it however constituted; justice, as a moral virtue, is not the creation of property but the conformity of our actions to those views of property which vary in the various states of society (a). The universal recognition of and respect for property and the rights of its owner are not the results of the wisdom or authority of patriots and legislators deliberating on what was best for the good and order of the community, but the results of a prior wisdom employed in framing a constitution not for a state but for human nature(b).

It now remains to call special attention to the specimens which the Society has received from Councillor Auer, of the Imperial printing office at Vienna, produced by the process known in Germany as " Naturselbstdruck," and in this country as" Phytoglyphy," or the art of printing from nature. These specimens include every variety of sub ject, botanical, geological, entomological, fossil, and fabrics. Very soon after gutta percha came into use, Dr. Ferguson Branson took impressions of leaves in that substance, and it occurred to him to try the effect of printing from the sunk impression so obtained, and one of the specimens now exhibited was produced in that way in 1847. It was found impossible to print them with a clear margin from the gutta percha, and this led to the use of an electrotype fac-simile in copper, which allowed of the margin being burnished and the plate wiped clean; this succeeded well. In 1850, Dr. Branson had occasion to get an object cast in brass, and the beauty of the casting was so great that he at once determined to have a cast made from a gutta percha impression of a fern, and see the result. When every part of the brass-plate was burnished with the exception of the impression, it was tested in printing, and the result proved most successful. When a few plates had been finished the subject was brought before the Sheffield Literary and Philosophical Society, on the 6th December, 1850, through which channel it reached the local newspapers, and was copied into various other prints. In the year 1851 Dr. Ferguson Branson communicated to the Society an Account of a Method of Engraving Plates from Natural Objects, which was read at a "The possessory feeling as the result of mere occupancy, meeting held on the 26th March in that year, and which is common to our nature and anterior to the application of was published in the Notices of Proceedings.

PROPERTY IN INVENTION(a). Mr. T. Webster has just published a work on the right of property in inventions and designs. The subject is one of great importance generally, and has peculiar interest for the members of this Society; it has, therefore, been considered that a statement of the principles adopted by the author will not be out of place in the Journal.

Mr. Webster thus commences his work. He

prietor of the fruit of his own labour, and that to whatever extent he may have impressed additional value on any given thing by the work of his own hands, to that extent, at least, he should be held to be the owner of it(c).
