He commanded sexscore of the prettiest men that ware in his broyer's armie, and especiallie the Clanwurchie were under his command, quho served him as under officers to discharge the dutie of marischall. His dutie wes, that in ye armies marching to ye enemies land, he should still guard the riar; and as the armie rested in ther camp, he still went in expeditiones to bring them hership* and provision, quhilk herschips were distributed as he liked, with the consent of the superior. His own pert of the hership was ilk cow quhose ear wes longer then hir horn, ilk black cow that had not a white spott in her bodie, ilk white cow that had not a black spott in her bodie, and ilk horse that wes wyt in three years; and his under officers had all the hedes of all the cowes that were killed in the camp.

ACCOUNT OF MR RUTHVEN'S IMPROV ED PRINTING PRESS. As one of the objects of this Magazine is to disseminate usef 1 knowledge, we cannot attain the end in view with better effect than by giving some account of a most important improvement in the mechanical part of printing, by Mr John Ruthven, printer, of this place. This very ingenious mechanician, having diligently studied his profession for upwards of twenty years, observed that there were numerous defects in the construction of the printing presses commonly employed, the principle of which is unaltered from the time of the invention of printing. The excessive and dangerous labour occasioned to the workmen, and the very imperfect adaptation of the press to many purposes, were the most obvious defects; to remedy which, by any improvement of the original machine, Mr Ruthven found, after diligent study, to be quite impracticable; something new; and, after much labour, he has succeeded in producing not only a highly useful press, but in giving a most beautiful application of a combination of levers, for the production of parallel motion, with a degree of power hitherto unequalled. right in their cloathes and armes, and he therefore resolved on attempting wytall to decern all the contravershies; quhilk place he managed so fortunatlie, that he was sent in all expeditiounes, and in everie expeditioune he was victorious. His good service gott him the reall affectioune of his broyer, so that his broyer, in his death-bed, left him his own sword, quhilk was the gretest merit a kinsman could haive, to haive the sword of such a brave conqueror, as a testimonie of faithfull service." The situation appears to have been lucrative; for he adds, "Ane estate from his broyer he needed not; ffor befor his broyer's death, by he prudent managment of ye benefi * " Herschip, Heirschip, Heiriscip, the act of plundering, devastation.-Booty, prey, &c." Jamieson. For the better understanding of the account we propose to give, it will be well to premise a few observations on the printing-press commonly used. Seld. The screw has hitherto been the power employed to produce pressure, while the types were placed on a moveable carriage, which was moved, after the ink had been applied, under the e for pressing. In consequence e power has always been limited-the radius of the lever which moves the screw being confined. It is also a consequence, that not more than one half of a large sheet could be printed at one descent of the screw. A most serious evil results from this, especially in printing duodecimo, because the pressure necessarily is applied twice to the centre pages of each sheet, while it is applied only once to the other pages. To these disadvantages may be added, the difficulty of ascertaining and regulating the degree of pressure; the irregularity of the motion of the lever; the severe labour, and excessive exertion of the workman; the nice accuracy in placing the types under the centre;-there being no difference, in point of trouble and labour, in printing a card and a folio; -and the necessity for placing small work always in the same spot, which necessarily wears out one part sooner than the others. In obviating these defects, Mr Ruthven has completely succeeded ;-and after giving some account of the construction of the new printing press, we shall point out the superior excellencies of it as briefly as possible. of the The general appearance of the large press is well represented in fig. 1.; of which fig. 2. is a complete section. In this press the types are placed on a stationary coffin or tablet, P; the paper is put on in the usual manner on the tympan, a, (fig.1.) and secured by the frisket, b. On turning over the tympans thus arranged, the platen, N (fig. 2.)-supported by the wheels, QQ, is drawn over the coffin by the handle, U, till the lower parts of the screw bolts, MM, be fully secured in the clutches, LL (fig. 2.); the lever or handle, A, is then turned over in the front of the press till stopped, when it will be nearly in a horizontal position. It is then restored to its original situation, the platen pushed back, the tympans raised, and the printing is completed. The mode in which this movement is produced is concealed by the check, R. The action which takes place in the above-described process will be best understood by a reference to, and examination of, the section, fig. 2. The platen is in this represented in its proper situation over the types. The parts of the external structure have been already sufficiently explained; it only remains to point out those which are exposed in the section. Beneath the tablet, P, and immediately behind the check, R, are the levers, Í I, having their fulcra at KK; to which are attached the clutches, LL, communicating as above mentioned with MM; the motion to which is given by the bolt, H, forming a point of union between the levers, I I. When their ends are depressed by means of the crank, EGF, which is moved by the handle, A, communicating to the crank, BC, and the connecting rod, D, the platen or upper surface, N, is forcibly drawn down upon the types. To maintain the relative position of the several levers, the balance-weight, S, is applied. TTT is the frame-work supporting the whole of the machinery. Such is as minute an account of Mr Ruthven's printing press as is necessary for general information. It is here proper to state some of the points of superiority which it has, very decidedly, over all other contrivances of the same kind. These may be very briefly detailed, as we have already pointed out the most glaring defects which first solicited Mr Ruthven's attention.-1st, In the new patent press the types remain stationary. 2d, The platen is the size of the whole sheet. 3d, Time is saved by its being brought over from the side. 4th, There is nearly half an inch between the tympans and the platen while passing over the types, by which all blurring is avoided. 5th, Any degree of pressure (from an ounce to twenty tons) may be correctly and uniformly given at pleasure. 6th, The platen being drawn down by the two ends, and the resistance sustained against the under surface of the tablet, affords the most complete and uniform security to all the parts; while, contrary to every other example known to us of the application of pressure, the frame is wholly independent of, and unaffected by, the force employed. 7th, As com plete parallelism between the two surfaces (viz, of the platen and coffin) is maintained by means of the two screws, O O, so a small piece of work may be done at either end without a supporting block at the opposite extremity. 8th, This press being entirely unattached, requires no levelling or staying; and one for demy royal requires a space of only forty-two inches square. 9th, The motions of the pressmen, though less severe, are sufficiently similar to enable him, in the course of one or two hours, to work with equal facility as at the common press. 10th, The principles above described are equally applicable to presses of all sizes. Fig. 3. represents one of the size of a cubic foot, which is capable of printing off an octavo page with greater celerity than a larger press, and may be worked on a common table without being fixed. The advantages of foolscappresses of this construction will be found very important. An ingenious application of the principles of this press has been made to copying manuscripts; for that purpose (although it may with perfect effect be done with the small printing presses) Mr Ruthven has contrived the press represented in fig. 4. which is made without the printing apparatus, and having, instead of the clutches, permanent pillars to connect the upper surface with the levers. The parallelism of the two surfaces is regulated by two graduated scales and indices at each end, as may be seen in the annexed figure. We are persuaded, that when, in addition to the excellencies already described, the extreme simplicity of the new patent press, and its little liability to derangement, are taken into consideration, it will in a short time supersede every other printing machinery that has hitherto been in use. M. ACCOUNT OF THE METHOD OF EN- MR EDITOR, THE increasing taste for the fine arts in this great literary capital, and the pretty eager attention now paid to them by the public in general, inspire a hope that you will allot a place in your Magazine for so interesting a department of polite and useful knowledge. Nothing can be more conducive to the promotion of the arts than publicity, which may be greatly accelerated through the medium of your publication, by the admission of discussions on the works of ancient and modern artists, explanations of their modes of representation, or descriptions of the implements or apparatus used by them for that purpose. To those desirous of information, you may thus furnish facilities of acquiring it; and to those willing to communicate the result of their experience, a reputable and easy channel to publicity. To the inexperienced, nothing is more discouraging than the difficulty with which practical information is to be obtained, with regard to the composition or management of the substances or implements to be employed in the arts in general. With this view, and trusting to a coincidence of opinion on your part, I beg leave to request the insertion of the following article on LITHOGRAPHY, or the art of engraving on stone, which I hope may be the means of calling forth other communications, either on the practice or criticism of the fine arts. This art has been long and successfully practised on the Continent, and we believe Germany has the honour of its invention. It was introduced into this country by a person of the name of Andrè about fifteen years ago, who attempted the publication of a periodical work, containing specimens of it by some of the most eminent artists in London, but which has been discontinued. It was also used in the Quarter-Master General's office, for the purpose of printing military plans, &c. In this country, however, it has never reached that state of perfection to which it has arrived on the Continent, as may be seen by a comparison of the works of Spix on craniology (in the college library), Albert Durer's Missal, and the Bavarian Flora; all of which are printed at Munich, and also the Flora Monacensis, and the last number of the Journal des Scavans; and these also furnish a proof of what may yet be done in the detail of this extraordinary invention. The great advantages which this art possesses over every other kind of engraving, are, first, that any person who can draw, can also execute the engraving with the same ease with which he uses the pencil on paper; 'and, secondly, the circumstance of his being enabled to have any number of copies taken at less than half the expense of ordinary copperplate printing. Nothing equal, it is true, to the tone, or minute elegance of the best line engraving can be produced, but an inspection of the works already mentioned, will show how admirably it is adapted to represent objects of a picturesque description, natural history, outlines, anatomical subjects, plans, &c. It is also applicable to the purpose of multiplying writings, as the subject can be written on the prepared paper, afterwards transferred to the stone, and then printed without delay, at no further expense than the printing. In this way all the proclamations of the state at Munich are made public. gum water and lamp black, and after it is dry, the design is drawn with the point of an etching needle, in the same way as on copper, cutting through the covering of gum and black, till the surface of the stone is reached, and then rubbing the solution into the lines or scratches. This done, it must be allowed to dry for the above mentioned time, and then soaked as before in water, when the gum will dissolve, leaving the lines only; upon which the printing ink is applied, as before explained, and the impression taken. Should this plan find a place in the Magazine, it is proposed to give, in some of your subsequent numbers, a short account of the history of the discovery, and of the methods used in common etching upon copper, together with some receipts for the preparation of the grounds, &c. Directions. A slate of white lias ANECDOTE OF THE HIGHLANDERS IN (Bath stone), about one inch thick, must be made perfectly level, and polished with very fine sand. The subject is then drawn on the stone with a common pen, and a prepared liquid of the consistence of common ink, and with the same facility; after this the stone is washed over with diluted nitric acid, which slightly corrodes that part of the stone only which has not been drawn on with the pen. The liquid is made with gum lac, dissolved in ley of pure soda, with a little soap, and coloured with lamp black. The liquid id upon the stone, after the design is drawn, must be allowed to dry for about four days, and then soaked in water till perfectly saturated; in this state (with the water on the surface), a common printing ball is dabbed over it as in type printing. This ink adheres to such parts as have been drawn upon, the other parts of the stone being wet, repel the printing ink; the impression is then taken, by passing it through a press with a single cylinder. When the print is wished to resemble a chalk drawing, the stone is left rather rough, by using a coarser sand to polish it; and instead of the ink and pen being used, a crayon made of the same materials (only with a larger quantity of the lamp black) is applied in the same manner as a pencil. There is another method by which it may be done, namely, by covering the stone over with a thin mixture of VOL. I. 1745. (Communicated by MARY LADY CLERK to the Publisher.) SIR, ACCORDING to your request this morning, I send you some account of the particulars that attended my birth,which I do with infinite pleasure, as it reflects great honour on the Highlanders (to whom I always feel the greatest gratitude), that at the time when their hearts were set on plunder, the fear of hurting a sick lady and child instantly stopped their intentions. This incident occurred November 15, 1745. My father, Mr D'Acre, then an officer in his Majesty's militia, was a prisoner in the castle of Carlisle, at that time in the hands of Prince Charles. My mother (daughter of Sir George le Fleming, Bart. bishop of Carlisle) was living at Rose-Castle, six miles from Carlisle, where she was delivered of me. She had given orders that I should immediately be privately baptized by the bishop's chaplain (his lordship not being at home), by the name of Rosemary D'Acre. At that moment a company of Highlanders appeared, headed by a Captain Macdonald; who, having heard there was much plate and valuables in the castle, came to plunder it. Upon the approach of the Highlanders, an old gray-headed servant ran out, and entreated Captain Macdonald not to pro R |
