The ninth paragraph on his first plate runs thus: tho’ we are obliged to have the ground-plane below the base-line,
yet the parts which are in it will be produced by the rules . above it, and as it were beyond it, at a distance in a per
fpective proportion, as those in the ground plane, are distant 6 from the base-line.
Here observe the first it signifies the ground-plane, the lecond it the base-line, the third it lias Itill another meaning, and the fourth it must signify the plane of the picture. The reft of the paragraph is nonsense : He should have said, åt à distance, whose proportion to the real given distance of the original object is regulated by the position of the spectator, is eye. Then comes a problem, teaching us to find the representation of a given point; in this problem he uses the term, vanishing point, without having first defined it.
In a subsequent paragraph he indeed tells us, tható $ * is the
vanishing point of the original line, AB; because the line « A B vanishes in that point. Which is not true, for it is the perspective representation S B, of the line A B, which vanishes in the point S, and were it as true as itis false, it could by no means be called a definition. He might as well have said, the line A B vanishes in the point S, because S is the vanishing point of the original line AB; or that two and two make fout, becaufe four consists of twice two.
Before we quit this first plate, we must observe the absurdities in which his wrong choice of a distance for the eye
has involved him; and first, The shaded side of the house, at H. which is a perpendicular plane, at right angles to the plane of the picture, scarce represents more than one fourth of the extent he ought to fuppose it. The fame blunder is committed again in the pier at. I. whose enlightened fide reprefents a plante at right angles to the pi&ture of only one fourth of the extent he supposes it, which is nionstrous. The direction of the shadows is false, and the distant steeple which terminates his view, exhibits a side which it is imporfible should be seen, if S be, as he supposes it, the center of the picture. This is a fault, that a child who had learned perspective a week, could not have committed. And what is more extraordinary, there is not one of the fix plates, which illustrate this work, but abounds in similar absurdities. Strange, that a man who despises knowlege, fhould take it in his head to be a teacher ; or that one who calls himself an artist, should
* Our readers, in general, it is hoped, will excuse our referring, in this manner, to Mr. B's plates, which we cannot copy --Thele paragraphs are more particularly intended for those who are poliered of Mr. B's book,
be at pains to publish a book, which fo evidently proves bim ignorant in every branch of the art he treats of.
One more extract from this treatise on perspective appears necesary, as it will fhew the reader how well Mr. Bardwell has kept the promise he made, that no mathematical knowlege should be necessary to understand his book.
There are many instances of his having forgot this: we shall content ourfélves with the fifth paragraph of the explanation belonging to the second plate. To
• In order to understand the nature of the generating lines, and angles, (not yet defined) - and the distance of the picture,
heing placed above the horizontal lines suppose they were • turned or lifted upon their axis, the vanishing line D Е, till
the eye-point 0 is directly opposite to the point of fight, ? then they would be in a visual plane, which passes from the
spectator's eye parallel to the ground-plane : the intersection of which plane, with the imaginary plane or picture, is the vanishing line of that plane, or horizontal line.'
Indeed Our Author had done well to recommend to his unmathematical readers that dictionary, out of which he picked all these hard words. For till such readers are acquainted with the fignification of such words, they may fancy their ignorance of mathematical terms, is the obstacle to their understanding Mr. Bardwell. We can, however, affure them, that the learned and unlearned may equally profit by the preceding paragraph: in which we apprehend the latent meaning is beyond the power of mere mathematicians to develop; so that if ever those gentlemen have puzzled Mr. Bardwell, it is not his fault if he is not now even with them.

POLITIC A L. 1. Fourth Letter to the People of England. 8vo. 25.
Collyer. Having pretty fully, tho' in a narrow compass, spoken of the three preceding pamphlets published by this Incendiary, under the title of, Letters to the People, we shall take up little more of our Reader's time, on the present occasion ; but content Ouricives with the following sketch of such patriots as Mr. Letterwriter, from a pamphlei entitled, An Impartial View, &c. See page 41.

II. A Letter to the Gentlemen of the Common-Council. By. a Citizen and Watch-maker. 8vo. 6d. Cooper. 2.-11. This is one of the few occafional productions that deserves to
be remembered, after the occasions which gave rise to them are elapsed. The author is pleased to call himself a Watch-maker; and in one page (24) he condescends to write in that character: but chen, as in another (15) he treats of an obftinate, unskilful pilot, and bad iteerage, in terms as accurate, he might as well have called himself a Mariner : and if we consider the general drift of his performance, the character of an Apothecary would have suited him better than any other. For tho'he addresses himself gravely to the Common Council, on the subject matter of their intended Address, and treats of the manner in which they ought to make their approaches to the throne, as the principal object of his attention; riezis plain, by the sequel, that this is done by way of vehicle only, for the more easy and effectual conveyance of a medicine, which he would have us believe is the only true catholicon for the disorders of the times. In thort, this occasional author takes parricular care (p.5) not to be mistaken for one of those gentlemen, who are patriots through their indigence, and whofe declamations are their luftence; and fo far forgets his watch-making character, even in the only page in which he makes use of it, as to offer the use of his poor abilities to Mr. Fowke, in case his affair should become a matter of national enquiry: which must imply, he has the honour to fit in one of the houses, at least : "for national enquiries can be made no where else ; 'nor, on such an occasion, could his abilities be elsewhere ferviceable,
What the ingredients are which compose this catholicon of his, it is fit should be unfolded in his own words, which here follow:
• Our patriot writers unanimously declare for turning oui all • the great officers of state, at present in the administration. This
proposal hath too much violence in it; nor is it easily pracți• cable.' fe hath an air of party, which would prevent its own
good effects, if it were carried into execution. It would proBably continue a
an unseasonable, and therefore destructive oppo** fition. Nor, for the honour of our country, would I willingly "ask, whether, if all these gentlemen were turned out, we have others of more unblemished integrity, and niore acknowleged * abilities, 'to fill all their places, However, there are too gentic
mén of apparent superiority to all others in 'either party. They • have both continued long in offices of greatest truit and power, with unsuspected reputation. They differed latt year in their
• judgment of public measures. Their contest was maintained • with a warmth, which might naturally rise from their mutual
conviction. Their reconciliation is now become necessary to ! the welfare, perhaps, to the very being of their country. If
their contest was of virtue, they will easily be reconciled. Great • spirits cannot long maintain little resentments, and if the love
of country be their prevailing paffion, it will fubdue all others ;' for in effect there is but one passion in the heart of man. Their
common friends may propose and settle the terms of their ! union ; but the nation, in these her distresses, calls upon them, • implores, conjures, I had almost said, commands them to unite. " She hath more than enough to gratify, their personal ambition ; • enough to indulge them in obliging and making happy their
• Permit me, Gentlemen, nor is it wholly foreign to the pur • pose of this Letter, permit me to mention some of those advan
tages, which, I am persuaded, will arise from this union. If they are each of them fuperior to every other man, most ca
pable of serving the puolic; if they were singly opposed to each : other lait win:er, who shall be able to form an opposition against
chem when united! The measures necessary to retrieve the honour of the nation, will easily then be carried into execution :
not distressed by midnight debates, which not only fruitlessly • consumed to rany valuable hours, but, muft have rendered the
speakers lifless and inat:engive to next day's, business. If they are no: wholly, inexcusable, in throwing away the winter in these unprofitar le debates, let us remember, that one of these
gentlemen was astuated by the human resentment of being • turned out of his employment; nor can we suppose him less • fenfibly affected for his friends. The other probably imagined,
if he could excuse the measures of the minister, for instance, the
Hellan treaty, he might have influence enough over him to direct • him afterwards to better counsels. But such is the gratitude of
ambition, that this gentleman must have been long since convin. ced, he was mistaken in his hopes ; and that a man lo tenaçious of governing, as obstinately to hold his power amid the errors, or let us call them the misfortunes, of his administration ; amidst the dangerous resentments of the people, will never admit a partner in his administration. For if we know any thing of this gentleman, feirfulness, and timidity is no
part of his character, from whence we may believe he had no : share in the late timid expedients, by which Minorca was loft. ! But, indeed, what share of power or confidence could. he exspect, who was at once feared and hated.?
Where indicacions are so Irong, labels are unnecessary: then as to the Medicine itself, it does not become. us to pronounce, whether the palate, the stomach, or, the constitution of the patient would bear it; and whether, it can be administred, or not, even the prescriber himself does not seem to have sufficiently con
fidered: Divide and govern is an old maxim; and it must be owned, this is no bad graft upon it. But party-policy is one thing, and public good another; and the interelting question to the community, is not, Who Mall govern us? but whether we can be governed better? And if fo, by what means ?
IV.

This is merely a new edition of a pamphlet first published in the year 1745 IV. An Impartial View of the Conduct of the Ministry, c. In' answer to the many invidious attacks of the Painphleteers, &c. 8vo. I's, Robinson.
We have here a performance which deserves a more than ordinary attention. Never were attacks of this kind made with more violence'; and never did great persons artacked discover more contempt, either for the matter they contained, or the consequences they might produce. The candid and confiderate, however, who desired to be informed of the merits of the case, by a full and fair hearing of both sides, could not help withing for fuch a Reply, as might furnish them with the premises they wanted : Such a Reply they thought was due to the public; and if not offered at all, they juftly apprehended the rath and censorious would be glad to infer, it was, because none satisfactory could be offered. Such a Reply is now before them'; for tho it is
called an Impartial View, it is, in effect, a Party-Vindication :"* founded on peculiar informations and instructions, as we are, in more!
than one place, given to undersand ; and from thence it derives its importance.
The two great points proposed by the Author to be examined, are there: .:-). Whether the ministers have acied upon principles of true
patriotism, and found policy? and in case any miscarriages may have happened, whether they are not to be attributed more to chance, and the want of that unattainable fore-knowlege, not in the power of man to acquire, than any defect in their capacities? And,
2. Whether feditious fpirits, who may have propagated infa. i mous reports, to the minifter's prejudice, are to be credited upon
their simple evidence, in opposition to facts, reafor, and their concomitant arguments ?
Of the intelligence on which this performance is founded, the Reader'is defired to accept the following specimens.
