"In the ruins of castles however, other countries may compare with ours. But in the remains of abbeys no country certainly can. "Where popery prevails, the abbey is ftill intire and inhabited; and of course less adapted to landfcape.

But it is the mode of architecture, which gives fuch excellence to thefe ruins. The Gothic ftyle, in which they are generally compofed, is, I apprehend, unrivalled among foreign nations; and may be called a peculiar feature in English landfcape.

"Many of our ruins have been built in what is often called the Saxon ftyle. This is a coarse, heavy mode of architecture; and feldom affords a beautiful ruin. In general, the Saxon prevails moft in the northern counties; and the Gothic in the fouthern: though each divifion of the kingdom affords fome inftances of both: and in many we find them mixed.

"What we call Saxon architecture feems to have been the awkward imitation of Greek, and Roman models. What buildings of Roman origin were left in England, were probably deftroyed by the ruthlefs Saxon in his early ravages. Afterwards, when Alfred the Great, having cftablished government, and religion, turned his view to arts, we are told he was obliged to fend to the continent for architects. In what fpecies of architecture the buildings of this prince were compofed, we know not: but probably in a purer ftyle, than what we now call Saxon; as Alfred lived nearer Roman times; and perhaps poffeffed in his own country fome of thofe beautiful models, which might have escaped the rage of his ancellors. Even now, amidst all that heavinefs, and barbarifm, which

we call Saxon, it is not difficult to trace fome features of Roman origin. Among the ruins of Brink, burn abbey, between Rothbury, and Warkworth, in Northumber land, we difcover in fome parts even Roman elegance.

"This ipecies of architecture is fuppofed to have continued till the time of the Crufades; when a new ftyle of ornament at leaft, fantastic in the highest degree, began to ap pear. It forms a kind of compo. fite with the Saxon; and hath been called by fome antiquarians the Saracenic though others difallow the term. Many ruins of this kind are ftill exifling.

:

"The English architect however began, by degrees, to ftrike out a new mode of architecture for himfelf; without fearching the continent for models. This is cal led the Gothic; but for what reafon, it is hard to fay for the Goths, who were never in England, had been even forgotten, when it was invented; which was about the reign of Henry Ii. It is befides found no where, I believe, but in England; except in fuch parts of France, as were in poffeflion of the English.

"In this beautiful fpecies of architecture the antiquarian points out three periods.

"When it first appeared, the round Saxon arch began to change into the pointed one; and the fhort, clumfy pillar began to clutter; but fill the Saxon heavinefs in part prevailed. Salisbury cathedral, which was finished about the year 1250, is generally confidered as a very pure fpecimen of the Gothic, in it's firt, and ruder form.

"By degrees improvements in architecture were introduced. The eaft-window being inlarged, was trailed over with beautiful fcrawl

work;

work; while the clustered-pillar began to increafe in height, and elegance; and to arch, and ramify along the root. In fhort, an intire new mode of architecture, purely Britifh, was introdu. ed. The grandeur of the Roman -the heavinefs of the Saxon- and the groteique ornament of the Saracenic, were all equally relinquithed. An airy lightnefs pervaded the whole; and ornaments of a new invention took place. The cathedral of York, and part of Canterbury, among many others, are beautiful examples of this period of Gothic archi

tecture.

"About the time of the later Henrics, the last period began to obtain; in the architecture of which the flat, stone roof, and a variety of different ornaments were the chief characteristics. Of this inriched ftyle King's college chapel in Cambridge, and Henry VII.'s at Westminster, are two of the molt elegant examples. The flat, ftone roof is generally, even at this day, confidered, as a wonderful effort of art. It is faid, that Sir Chrifto. pher Wren himfelf could not conceive it. He would fay, "Tell

me where to place the first stone;

and I will follow it with a fe▾ "cond.”

"This ftyle is generally confidered as the perfection of Gothic architecture. I own, it rather appears to me the decline of the art. The ornaments fo affectedly introduced, and patched on; as the rofe and portcullis in King's college chapel, have not, in my eye, the beauty of the middle ftyle; in which every ornament arifes naturally from the feveral members of the building; and makes a part of the pile itself. Nor has the flat roof, with all it's ornaments, in my opinion, the fimplicity and beauty of the ribbed, and pointed

one.

"Abbeys formerly abounded fo much in England, that a delicious valley could fcarce be found, in which one of them was not ftationed. The very fites of many of thefe ancient edifices are now obli terated by the plough; yet fill fo many elegant ruins of this kind are left, that they may be called, not only one of the peculiar features of English laudfcape; but may be ranked alfo among it's moft pictu refque beauties."

Dr. HERSCHEL's ACCOUNT of the DISCOVERY of TWO SATELLITES revolving round the GEORGIAN PLANET. [From the Seventy-feventh Volume of the Philofophical Tranfactions,]

"TH

HE great diftance of the Georgian planet, and its prefent fituation in a part of the zodiac which is fcattered over with a multitude of fmall ftars, has rendered it uncommonly difficult to determine whether, like Jupiter and Saturn, it be attended by fatellite. In purfuit of this inquiry, having frequently directed large telefcopes to this remote planet, and finding myfelf continually difappointed, I afcribed my failure to the want of fufficient light in the inftruments I ufed; and, for a while, gave over the attempt.

"In the beginning of last month, however, I was often furprifed when I reviewed nebule that had been feen in former fweeps, to find how much brighter they appeared, and with how much greater facility I faw them. The caufe of it could be no other than the quantity of light that was gained by laying afide the fmall fpeculum, and introducing the front-view; an account of which has been inferted, by way of note, to the catalogue of nebule contained in the Philofophical Transactions, vol. lxxvi. P. 499.

It would not have been pardonable to neglect fuch an advantage, when there was a particular object in view, where an acceffion of light was of the utmost confequence; and I wondered why it had not ftruck me fooner. The 1th of January, therefore, in the courfe of my general review of the heavens, 1 felected a fweep which

led to the Georgian planet; and, while it paffed the meridian, I perceived near its difk, and within a few of its diameters, fome very faint ftars whofe places I noted down with great care.

The

"The next day, when the planet returned to the meridian, I looked with a moft fcrutinizing eye for my fmall ftars, and perceived that two of them were miffing. Had I been lefs acquainted with optical deceptions, I fhould immediately have announced the existence of one or more fatellites to our new planet but it was neceffary, that I fhould have no doubts. leaft hazinefs, otherwife imperceptible, may often obfcure small stars; and I judged, therefore, that nothing lefs than a feries of obfervations ought to fatisfy me, in a cafe of this importance. To this end I noticed all the small stars that were near the planet the 14th, 17th, 18th, and 24th of January, and the 4th and th of February; and though, at the end of this time, I had no longer any doubt of the exitence of at least one fatellite, I thought it right to defer this communication till I could have an opportunity of feeing it actually in motion. Accordingly I began to purfue this fatellite on Feb. the 7th, about fix o'clock in the evening, and kept it in view till three in the morning on Feb. the 8th; at which time, on account of the fituation of my houfe, which intercepts a view of part of the ecliptic, I was obliged to give over the chace: and

during

during thofe nine hours I faw this fatellite faithfully attend its primary planet, and at the fame time keep on, in its own courfe, by defcribing a confiderable arch of its proper orbit.

While I was chiefly attending to the motion of this fatellite, I did not forget to follow another finall ilar, which I was pretty well af fured was alfo a fatellite, efpecially as I had, on the night of the 14th of January, obferved two fmall flars which were wanting the 17th, and again miffed other two the 24th which had been noticed the 18th; but, whether owing to my great attention to the former fatellite, or to the clofenefs of this latter, which was nearly hidden in the rays of the planet, I could not be well af fured of its motion. Indeed, towards morning, when a change of place, in fo confiderable an interval as pine hours, would have been moft confpicuous, the moon interfered with the faint light of this fatellite, fo that I could no longer perceive it.

"The first moment that offered for continuing thefe obfervations was on Friday the 9th, when I faw my first difcovered fatellite nearly in the place where I expected to find it. I perceived alfo, that the next fuppofed fatellite was not in the fituation where I had left it on the 7th, and could now diftinguish very plainly that it had advanced in its orbit, fince that day, in the fame direction with the other fatellite, but at a quicker rate. Hence it is evident, that it moves in a more contracted orbit; and I fhall therefore call it in future the firit fatellite, though last difcovered, or rather lait afcertained; fince I do not doubt but that I faw them both, for the first time, on the fame day, which was January the 11th, 1787. "I now directed all my atten

tion to the first fatellite, and had an opportunity to fee it for about three hours and a quarter; during which time, as far as one might judge, it preferved its course. The interval which the cloudy weather had afforded was, however rather too fhort for feeing its motion sufficiently, fo that I deferred a final judgment till the 10th; and, in order to put my theory of these two fatellites to a trial," I made a fketch on paper, to point out before-hand their fituation with refpect to the planet, and its parallel of declination.

"The long expected evening came on, and, notwithstanding the mot unfavourable appearance of dark weather, it cleared up at last. And the heavens now difplayed the original of my drawing, by fhewing, in the fituation I had delineated them, the Georgian planet attended by two fatellites.

"confefs that this fcene ap peared to me with additional beauty, as the little fecondary planets feemed to give a dignity to the primary one, which raifes it into a more confpicuous fituation among the great bodies of our folar fystem,

"I have not feen them long enough to affign their periodical times with great accuracy; but fuppofe that the first performs a fynodical revolution in about eight days and three-quarters, and the fecond in nearly thirteen days and an half.

"Their orbits make a confiderable angle with the ecliptic; but to align the real quantity of this inclination, with many other par ticulars, will require a great deal of attention, and much contrivance : for, as estimations by the eye cannot but be extremely fallacious, I do not expect to give a good account of their orbits till I can bring fome of my micrometers to bear upon them; which, thefe last nights, I

have

have in vain attempted, their light being fo feeble as not to fuffer the leaft illumination, and that of the planet not being ftrong enough to render the fmall filk-worm's threads

of my delicate micrometers vifible. I have, nevertheless, feveral refources in view, and do not defpair of fucceeding pretty well in the end."

Dr. HERSCHEL'S ACCOUNT of THREE VOLCANOS in the

[ocr errors]

MOON.

[From the fame Work.]

"IT will be neceffary to fay a few words by way of introduction to the account I have to

give of fome appearances upon the moon, which I perceived the 15th and zoth of this month. The phænomena of nature, efpecially thofe that fall under the infpection of the aftronomer, are to be viewed, not only with the ufual attention to facts as they occur, but with the eye of reafon and experience. In this we are however not allowed to depart from plain appearances; though their origin and fignifica tion fhould be indicated by the most character fing features. Thus, when we fee, on the furface of the moon, a great number of elevations, from half a mile to a mile and an half in height, we are ftrictly intitled to call them mountains ; but, when we attend to their par ticular fhape, in which many of them refemble the craters of our volcanos, and thence argue, that they owe their origin to the fame caufe which has modelled many of thefe, we may be faid to fee by analogy, or with the eye of reafon. Now, in this latter cafe, though it may be convenient, in fpeaking of phænomena, to ufe expreffions that can only be juftified by reafoning upon the facts themselves, it will certainly be the fafelt way not to neglect a full defeription of them, that it may appear to others how far we have been authorized to use the mental eye. This being premifed, I may fafely proceed to give my obfervations.

"The volcano burns with great. er violence than last night. I believe its diameter cannot be lefs than 3", by comparing it with that of the Georgian planet; as Jupiter was near at hand, I turned the telefcope to his third fatellite, and eftimated the diameter of the burning part of the volcano to be equal to at least twice that of the fatellite. Hence we may compute that the fining or burning matter mutt be above three miles in diameter. It is of an irregular round figure, and very sharply defined on the edges. The other two volcanos are much farther towards the center of the moon, and resemble large, pretty faint nebule, that are gradually much brighter in the middle; but no well defined luminous fpot can
