Hitherto we have been speaking of M. Delambre's complete treatise in three quarto volumes. Of his 8vo. Abridgement we need not say much. It is conducted upon the same plan as the larger

:

work, but with fewer details, fewer developments, fewer tables, fewer examples to illustrate the theoretical processes, and a less variety of methods. In the complete treatise, it was the object of the Author to give all which might be useful to the professed astronomer, except what relates to physical theory in the Abridgement, he has restricted himself to the exhibition of such theorems and processes, as may serve for one who wishes to obtain a correct idea of the science, without attaining expertness as an observer, and without tracing all the minuter points which would be examined with care by the profound investigator. In the publication of the two works, the Author followed a different course from what has been usually pursued, and permitted ́the Abridgement to appear about two years before the larger treatise from which it was extracted.

We shall conclude with two remarks. First, Although these volumes are by no means such as English readers in general will be inclined to regard as elementary, they are certainly not of difficult perusal. Let any one who is moderately conversant with geometry, analytical trigonometry, and the first principles of the Differential Calculus, set himself in good earnest to go through the Chevalier's longest investigations; and, how startling and formidable soever they may at first appear, he will find them comparatively simple. This arises from the Author's admirable perspicuity, and his true regard to logical order.

Secondly, We know of no work in which writers of all countries are quoted, and their methods described, adopted, criticized, or amended, with so perfect a freedom from national partiality. M. Delambre seems to regard science as of no country, or we should rather say, of all countries. The English, Germans, Swedes, Italians, Spanish, Sicilians, men of all countries, and of all ages, are made to contribute to this great work: all are treated fairly; their talents are duly appreciated; the merits of their respective improvements and discoveries unhesitatingly admitted; and every one who has in any measure promoted the science, if his labours are known to our Author, receives ample justice. This is truly an enviable example of candour!

On the whole, we regard the Chevalier Delambre's as by far the most comprehensive, methodical, and erudite treatise on astronomy which has yet appeared. Unfortunately, it abounds with press errors: but we have no doubt that the Author will soon be enabled to lay before the world a new edition in which these will be removed: we shall then regard his performance as one of the finest models of human genius and industry which have been produced in the nineteenth century.

Art. VII. The Cross-Bath Guide; being the Correspondence of a Respectable Family upon the subject of a late unexpected Dispensation of Honours. Collected by Sir Joseph Cheakill, K.F. K.S. &c. &c. &c. fcap. 8vo. pp. 92. Price 3s. 6d. Underwood. 1815. THERE is a considerable proportion of satirical humour in

this jeu d'esprit. Its design is to expose the alleged impolicy and absurdity of the late liberal dispensation of military honours, in the creation of a legion of knights. The invidious partiality of the distinction conferred, the mockery of an empty title to those who have not the means of supporting it, the embarrassments introduced in the court of precedence, by the new creations, and the unhappy effect on female vanity of honours so unexpected, are depicted with a great degree of spirit and shrewdness, and in easy versification. The title will immediately remind our readers of Mr. Anstey's humorous produetion. If the imitation is not quite equal, in point of wit, to the original, it has the superior merit of being free from those violations of decency which disgust us in the New Bath Guide. One verse, however, in the song, at p. 47, we wish that the Author had not obliged us to mark as an exception.

The following will serve as a sample of the letters. It contains an account of the first dinner given by Mr. Hitchins on occasion of his son Thomas's elevation to the dignity of a Star, and is addressed by Miss Margaret Capper to her sister Dinah at Bath.

I wrote all the cards, and can fully explain

Who and who were the folks that composed the grand train;
Though Cousin invited some brother stars too,
But with him and his set I had nothing to do.
Each name on the list I'm about now to send,
Is that of some great and particular friend.
Sir Audrey Fitztrollop, whose shield has a bar,
But cover'd, he hopes, by a red hand, and star;
The Rev. Sir Luke Chaplyn, for lawn rather wild,
Promoted for christening Lord Faddleville's child;

Sir John Jukes, Sir Mark Hicks, Sir Job Snipe, Sir James
Hare,

All four, in succession, of London Lord Mayor;
Sir Christopher Congo, the India Director,
Of a trade to the Terra Stultorum projector;
Sir Benjamin Billings, who brought his own dish,
Of the company chairman for catching fresh fish ;
The great farrier-surgeon, Sir Parkynson Proctor,
Sir Timothy Clearwell, our family doctor;
Five stars of the navy, and three of the army-
A party like this is enough to alarm ye!

In truth uncle Hitchins was caught in a scrape
By the party assembled, but made an escape

Through native good-humour. When dinner was served,
As rights of precedence are strictly observed
On solemn occasions, no creature would stir,
For no one there present was less than a Sir.
Off hobbled my uncle, as bowing they stood,
And left Tom to drill them as well as he cou'd,
(Which cannot be done, now, in due etiquette,
Without a Court Guide, or a London Gazette :)
When dinner began, what a fuss and a pother!
The guests soon perceiving each Sir had his brother;
Their host himself simper'd, with honour elated,
And never perceived what in looks they debated-
All trades and professions, of dignity jealous,
Are piqued to be elbow'd in rank by their fellows :
Though Peers precede Knights without any demurs,
A Sir, of one calling, hates all other Sirs.

My uncle presided with wonderful grace

you

"Sir Benjamin, fish? Aye, you like a good plaice;
"Sir Giles, you were young when enter'd the navy!
"Sir Job, let me give you a little more gravy;
"Sir Parkynson, used to the same sort of work, he
"Sir Philip, will help you to cut up the turkey;
"Sir Harry, how long have you had your dragoons?
"Sir John, wait a moment, there's plenty of spoons;
"Sir Christopher, try this receipt for your curry ;
"Sir James, let me beg-help yourself-there's no hurry;
"Sir Timothy, jelly? 'tis wholesome you know:
"Sir Mark, things look ill, omnium's shockingly low"
"Mr. Hitchins, I think half the city will break.”
Mr. Hitchins began, at this word, to awake."

Art. VIII. Brief Memoirs respecting the Waldenses, or Vaudois, Inha bitants of the Valleys of Piedmont; the result of Observations made during a short Residence among that interesting People in the Autumn of 1814. By a Clergyman of the Church of England. 18mo. pp. 42. Price 1s. Hatchard. 1815.

THIS simple memorial cannot fail, we think, to accom

plish its benevolent object. It is an appeal in behalf of an interesting people, whose very name constitutes a claim upon the affectionate sympathy of their fellow Christians, - descendants of a class of men who were, for a series of 66 ages, "destitute, afflicted, tormented;" but " of whom the "world was not worthy!" With the character and history of the ancient Waldenses, their exalted heroism and cruel sufferings, few of our readers, we should hope, are unacquainted.

:

It is a page of history with which every Protestant especially ought to be familiarised and the public are indebted to Mr. Wm. Jones, the author of a recent publication on the "History of the Waldenses," for bringing forward the subject again more prominently into general attention.

It appears that their more recent history discloses persecutions equally atrocious and sanguinary. To the Author of this "Brief Memoir" was presented, by a minister of the valleys, an affecting relation of their sufferings in 1686, when Louis XIV. instigated the court of Turin to measures correspondent to his own ferocious proceedings at the revocation of the Edict of Nantes. It is a manuscript of about one hundred years old; and the truth of its contents is attested by ten ministers, assembled in synod, the 19th Oct., 1716. We must be allowed to express our earnest hope that the manuscript, from which extracts are given, will not be suffered to remain longer in obscurity.

It is with the character and condition of the present simple occupiers of the valleys, that it is particularly the object of this Memoir to make us acquainted, with a view of exciting an active interest in their behalf. We need only add, to ensure its circulation among our readers, that any profit arising from its sale is to be devoted to the object for which it pleads. It is in contemplation to appoint a Committee to superintend the effective distribution of any sums of money which may be raised for the Vaudois. The author justly remarks that it is unquestionably the duty of believers to endeavour to promote, and to pray for a revival of piety in churches once renowned, as well as for the diffusion of Divine truth among the heathen.'

Art. IX. Religious and Moral Reflections, originally intended for the Use of his Parishioners. By Samuel Hopkinson, S.T.B. formerly Fellow of Clare Hall, Rector of Etton, and Vicar of Mortoncum Hacconby. Second Edition. pp. 203. price 4s, Harris. 1814. THIS is certainly a curious performance. Seldom have we

met with so great a medley of incoherency, absurdity, and false doctrines. A few lines will be amply sufficient to convince our readers that this is not an unmerited censure. Immediately after the ample title page, and a table of contents equally singular, a kind of glossary is abruptly introduced, without any explanatory reason assigned, consisting of several hundred words, of which the following are specimens. The unlettered inhabitants of Morton cum Hacconby are gravely informed by their vicar, that 'to detract,' is to draw from;' that continual,' signifies without opposition;' that the author,' is the
