any other Instruction, learn to form the five Orders, and find the Quantity of their several Parts, with every particular Ornament belonging to the same; as also thoroughly acquaint himself with whatever is neceffary to be known in Architecture, so far as regards the proper and exact Disposition of the Parts of all perfectly fine Buildings, or to the Order, Symetry and Beauty of every truly magnificent Structure.

Let me add, with respect to this excellent Inftru. ment, whereby so many valuable Problems are refolved, that it is capable of receiving Scales, not only for Architecture, but also for Geometry, Dialling, Arithmetick, and Musick; the manner of applying it to all which may be immediately gathered from the Directions concerning the Use of it, with relation to the Subject of this Treatise ; whereof it may fuffice to give the following general Account.

The Author, after a short Description of the Fabrick and Division of the Parts belonging to this Inftrument, shews, in XLIX Operations, how to delineate all the Parts of the different Orders in Architecture, by means of it, with greater Facility than can be effected by any other Method whatsoever.

He begins with the Tuscan, that being the first, fimplest, and most easy; by the Example of which any one may readily comprehend how to form the other Orders. What he teaches us with respect to this is, to form Colonades and Arches with and without Pedestals, to form Doors, Niches, Basements, the Entablature and the Cornices of Doors,

In the Dorick Order, which has a great Affinity with the foregoing, differing in nothing but the Lines, he instructs us how to place Doors within Colonades and Arches, with and without Pedestals; how to difpose them in plain Fronts, and make them proportional to Niches. We have here likewise an useful Observation upon the Cornice in the Entablature of this Order, and a Method by any Cornice to form another greater or less, in one given Proportion. In the Ionick Order, he Thews how Niches are to be

placed

[ocr errors]

placed within Colonades and Arches, with or without
Pedestals, on each side of Doors, and in plain
Fronts; with some proper Remarks in regard of the
Basements, and of the Capital in the Ionick Entabla-
ture, with Directions to form the Orders with their
Members of any required Dimensions.

Having taught us how to form the Orders, and

place Doors, Niches and Windows within Colonades

and Arches; to render the Work yet more serviceable,

our Author proceeds to inform us, how to measure

them by the Instrument, know the Quantity of their

several Parts, and place them in great Building. All

this is exemplified in the Composite Order; in treating

of which he furnishes us with divers Methods of

Mensuration, and proposes some necessary Cautions

relating to them : He directs us how to vary the

Members, either for Beauty or to lessen Expence,

and place the Parts of one Order in another ; like-

wife in what Manner those Members are to be made

proportional to the Parts of the Orders wherein they

are to be placed, and finally to take away from a

Profile any one of its Members, and enlarge the

others proportionably: This last Article is preceded

by an Observation upon the Capital in the Composite

Entablature.

When we come to those Plates whereon the Corin-

thian Order is delineated, our Author lays down a
Variety of Instructions for placing the Orders the one
upon the other, for forming them by any given Ra-
tio's, for making a Capital or Base suitable to any
given Column that wants either, and, vice versa, for
adjusting a Column to any given Capital; with other
Problems of a like Nature, equally requisite to the
Perfection of the Art here insisted on.
· TheWork concludes with several necessary Rules for

the particular Ornaments of the Orders, as Ruting the

Columns, turning the Voluta and Scrolls, shewing how

the latter are to be applied to the Cornices, and also how

Balusters and Colonets are to be gracefully shaped.

There are fifty Folio Copper-Plates in this Volume,

ARTICLE III. A LETTER to Dr. Pemberton, from the Author

of the Queries proposed to bim in September and November.

SIR; AS

you

had done me the Honour, tho' an anonymous Writer, to return some Answer to the Queries I proposed to you in September last, I flatter'd myself with the Hopes you would have shewn the same Regard to those I laid before you in November ; and the rather, for that something of a Reply to these last seemed indispensably necessary, in order to clear you from the Suspicion of wilful and premeditated false Quotation ; a thing, you know, which is not only a shrewd Sign of a bad Cause, but a certain Proof of a bad Mind.

Had you been pleased to gratify this Expectation, I should have thought it incumbent on me, as a Friend to Truth and Plain-dealing, either to declare myself fully fatisfy'd with your Reply, or, in case it were insufficient and wanted any farther Explanation, to have given you the Trouble of a few more Queriesa

But, by your late Advertisement, finding myielf utterly disappointed in these Hopes, I intend not to importune you any farther, but İhall for the future be as filent as Philalethes. In this Condition you cannot, fure, be so ungenerous as to insult me. You see plainly my Silence, as well as his, is only conditional. I shall be silent, unless you answer my Queries; he, UNLESS you explain the Lemma. You know how to open both our Mouths whenever you think fit.

But, as the answering my Queries may be fomething difficult, and to explain the Lemmá otherwise than he has done, is, you know, utterly impossible, I take it for granted our Correspondence is at an end. I have therefore nothing more to say, but to congratulate you upon this new Method you have invented, of putting all Adversaries undoubtedly to Silence, by being filent yourself, in regard to the Point in which the Essence of the Controversy confifts, upon this Parthian Manner of routing the Enemy by running away from him.

This, Sir, does you no less Honour than the fingular and surprising Argument you have invented to justify your Method of Quotation : A Reason unthought of by the ablest Controversial Writers of all Ages, past or present. How would fome Persons we have known, have hugg'd themselves, had they but thought of such a Reason! What Advantage would it not have given them over a B-----t, or a C----ke, a H-----y, or a L----ck? They might then have been at full liberty to quote the Words of their Antagonists by piece-meal, in order to give them a Meaning the Writer never thought of, and to suppress such other Words as must have shown the real Meaning of what were quoted, such Words as, in your Phrase, had Power to metamorphose the false Proposition, they censured, into a true one : had they on this Account been charged with foul Play, it was only saying, I left out such Words, because I looked upon them as subjoined by way of Interpretation, and all Mankind must have been fatisfied. After an Answer so abundantly sufficient, they might fairly have said with you, it seems so express and full, that to attempt any farther Explanation of it would be no less than an Affront to the Understanding of every Reader.

But amidst all these Commendations, which you so highly deserve, and I as freely bestow, I must take the Liberty to acquaint you with one or two Particulars, in your late Advertisement, which I a little mislike.

You seem to have forgot the Purpose of your Writing, which, you say, is fully accomplished. Was it to put Philalethes to Silence ? Or, to make Sir Isaac Newton's Doctrine be clearly undersiood, and freed from Objections as. Speedily as possible Philalethes, you know, made no Objections.

Also

Also you, who are deservedly looked upon as a Cenfor. Morum to other Writers, should, methinks, have abstain'd from such unpolish'd Terms, as Cavils, groundless Confidence, trifling Altercation, and especially from so coarse a Word as Nonsense. This laft, I need not tell you, seems to bear a little hard upon Sir Isaac Newton. Once before, out of the Respect due from you to his Memory, a softer Phrase was used, unguarded Words. Unguarded, tho' at the same time the wary old Knight cry'd out, Cave. But whether Nonsense, or unguarded Words, I must acquaint you, Persons of clearer Heads differ from you in that Particular.

You say likewise, I still think those Answers to express and full, &c. How, Sir? STILL? What after you have read

my

laft Queries? In this, the Opinion I have of your Understanding makes me almost doubt of your Sincerity ; and I am afraid, those, who are persuaded of your Sincerity, will be apt to question your Understanding. I am,

S IR,
Your very humble Servant,

The Author of the Queries.

ARTICLE IV. IL Lately mentioned a Dispute upon some very abstruse

Subjects, carried on by an Epistolary Intercourse between the Rev. Mr. Jackson and William Dudgeon a Gentleman in Berkshire. The Letters of both were printed together a few months ago, for John and Paul Knapton, at the Crown in Ludgate-street, in an Ostavo Pamphlet. Since then a second Collection has been publish'd in the fame Size, by the same Booksellers. As I am apt to believe the Controversy is come to an Issue, I shall now present the speculative Reader with a Summary of it. In general it concerns the Immensity and Unity of God; the Existence of material and spiritual Substance; God's mo
