At fix, being laid on the snow, it fell to 13° below o.

At nine, it sunk to 14', and at one, the next morning, continuing in the same situation, the mercury had fallen to 23° below o; nor does it appear to have risen more than 2 or 3 degrees at any one period from that time till 8 o'clock: a thermometer suspended at the same time, in the open air, appears constantly to have indicated a degree of cold much inferior to that indicated by that which lay on the snow. Thus, when the former stood at 12° below o, the latter stood at o; and while the former was 23° below o, the latter stood at -7, that is, 160 degrees higher.

By blowing on the snow contiguous to the ball of the thermometer, by a pair of bellows properly cooled, when the mere cury stood at 22 below o; the cold was so far from being increased, that at the end of two minutes the mercury had risen no less than 10°; for it now pointed only to 12° below o. Dr. Irvine affifted at this experiment, which was made with a view to try whether the snow might not be still further cooled, by an evaporation at the furface, promoted by the action of the bellows.

In the experiments made on the following day (January 23), when the cold was not so intense, it appears that the thermometer in the air was constantly from 6 to 10 degrees higher than that laid on the snow. Thus when the former ftood at +14°, and afterwards at +5°, the latter at the same times was funk to +4°, and -3. A thermometer which had been sufpended a little above the leads of the observatory, being laid on some hoar-froft, three fourths of an inch deep, which had settled on a piece of thin board, never failed to fink at least 6 degrees; but when it was laid upon pieces of stone, from which the hoar frost had been brushed away, the mercury funk very little. Article 30. - Account of an extraordinary Pheasant: By Mr. John

Hunter. The subject of this account is a hen pheasant, with the feathers of a cock. The Author, after offering several general observations, concludes, that it is most probable that all those hen pheasants which are found wild, and have the feathers of the cock, were formerly perfect hens; but that they are now changed by age, and perhaps by certain constitutional circumftances.' Article 31. A Letter to Joseph Banks, Esq; P. R. S. &c.

from Daniel-Peter Layard, M. D. F. R. S. &c. relative to the Distemper among the Horned Cattle.

In this Paper the Author lays before the Society the result of his observations and correspondence, with respect to the contagious distemper among the cattle, since the year 1769; when he was called upon by government to aslist with his advice to stop its progress, on its breaking out in Hampshire. The falutary

orders

orders then and afterwards issued, to kill the infected cattle immediately, by strangling, and to bury the carcases whole, together with their litter, &c. have effectually extinguished the disease in this country, as well as in Flanders, Picardy, and the South of France ; where the British system was adopted.

In Denmark, where the disease has become naturalised and general, the government have adopted the regulations issued in Great Britain, and have likewise pursued the practice of inoculation, which appears to have been successful. The Author af. firms, that this disease is an eruptive fever, of the variolous kinds bearing all the characteristic symptoms of that disorder ; with this distinctive property, that no beast which has had it, either naturally or by inoculation, is ever attacked by it a second time. Article 34. Thermometrical Experiments and Observations: By

Tiberius Cavallo, F.R. S. The Author having been appointed to write the annual Difsertation, pursuant to the institution of the late Mr. Baker, has chosen for the subject of it certain experiments made with thermometers three or four years ago; particularly with respect to the effects produced by painting their bulbs black, or of different colours. It will not appear strange that a thermometer, the bulb of which had been painted black with Indian ink, should, on being exposed to the sun's rays, indicate a degree of heat about 10 degrees above that shewn by a similar thermometer, which had not been painted : but it will appear remarkable, that when the thermometers were only exposed to the strong daylight, the mercury in the former constantly rose one-third of a degree, and sometimes even three-fourths, or even a whole degree, above that in the latter.

In this Paper the Author describes a very easy and expeditious method of graduating thermometers of various lengths or fizes; by by means of a board on which a piece of white paper is pafted, and on which a right angled triangle is drawn, one side of which is divided into equal parts, or degrees. This inftrument may be considered as a universal scale, and must be very useful to those who are engaged in experiments that require the use of a great number of thermometers : but a more particular description of it cannot well be rendered intelligible, without the affistance, of the plate in which it is delineated.

ART. VII. The Royal Suppliants. A Tragedy. As performed at the Theatre Royal in Drury-Lane, 8vo.

Bowen, 1781. To this tragedy the Author (the Rev. Dr. Delap) has pre

fixed the following Advertisement : * It may perhaps be necessary !o acquaint the reader, that Euripi. des has written a tragedy upon the same subject. In his Heraclida, Macaria is sacrificed in ihe second act, and never afterwards mentioned ; and Acamas is a mute, Indeed the whole conduct of this play is so entirely different from that of the Greck poet, that the author is hardly conscious to himself of having borrowed any thing more from him, than the general idea of the Suppliants taking refuge in the temple, and Macaria's voluntary offer of her own life,

There are few dramas, among the remains of the ancient tragic ftage, that seem to afford less temptation to a modern playwright than the Heraclidæ of Euripides. The fable is not, like Medea, dipus, Philoctetes, Iphigenia, &c. founded on one of those popular classical stories, with which every dabbler in antiquity is luperficially acquainted. The Prologue, indeed, has called it, the tale that Bufby taught :' this may be true of the Adventures of Hercules ; but we will venture to affert, that many a school-boy has left Westminster, without ever having heard of the sacrifice of MACARIA. The Greek play itself too, though written in a vein of pathetic fimplicity, is constructed on rather too severe a model for the English Itage. Our Author, however, has borrowed more from the Greek poet than he handfomely acknowledges. Not only the general idea of the Supe pliants taking refuge in the temple, and Macaria's voluntary offer of her own life ;' but, among other matters, particularly the character of Alcander, though under another name, and the death of Eurystheus by the hand of Hyllus. In Euripides, indeed, ' fcamas is a mute.' Acamas, by Dr. Delap, is transformed into a lover; one of those infipid gallants, those Drawcansir amorosos, that over-run our modern tragedies. The same dramatic craft is exercised on the oracle, a falsification of which is aukwardly produced, by an unnatural connection bctween the Herald of Argos and the Priest of Athens. By these means, the regal cares of Demophon are degraded, the filia! paflions of Macaria are weakened and divided, and the touching fimplicity of the ancient drama is ill exchanged for the una interesting complications of a modern tragedy.

The following is, we apprehend, in the Author's estimation, the capital scene in the piece : Solemn Mufic. Allow Proceffion. MACARIA dreft like a Victim, at

tended by Priessa Demophon.

Holy men, approach,
And execute your office. Demophon
No longer heaven's refilless will withstands.
Uninterrupted now the victim lead

To facrifice.
Theftor.

Virgin, thou there discern'ft
Great Juno's temple : with profoundeft reverence,
Behold the servant of the sacred goddess

Conducts thee to the altar,
Macaria.

Gods above!
To you Macaria lifts her latest prayer ;
To you devotes herself for a lov'd parent.
Oh, let the fighs of innocence, to which
Your heavenly gates stand open day and night,
Find entrance ! Let the virtues of her son
Lighten her loss of me!, comfort them both!
The Queen and Hyllus comfort! for ye can,
Tho'
poor

Macaria cannot. Without pause,
Now do your office, priest. Nay, touch me not ;
Freely to death I follow.

[She walks, attended; towards the Temple, with folemn mufic. Demophon.

Now, my son,
Conon shall live; and Juno be appeased.

DEIANIRA and Iolaus from the Temple,
Deianira. Hark, Iolaus! heard you not the sounds

Of sad folemnity? and lo, attired
By virgin vest-Earth hide me from the fight!
'Tis the! oh horror, horror! my dear daughter
Led forth a victim!-closer yet my child,
And closer! he who tears thee from thy mother

Shall bring the Furies with him.
Demophon.

Deianira!
Alcander. Curft accident!
Demophon.

Priests, do your office
Deianira.

Hold!
Thou bloody tyrant, hold !--oh, loft to all
Humanity ! "from dæmons sprung thou art!
From vengeance, murder, death! whate'er of horror
Lays wake the world !-- Could not her innocence,
Youth, beauty, all! not all, but yet thou could't not!
Tyrant, thou dar'ft not do it! the very itones
Would from this violated altar fart,
In vengeance of the crime! Heaven's wrathful King
Blast with his bluelt lightning !-Oh, wbat fiend
From hell could sempt thee to so damned a deed?
T 4

Demoph

Demophon. Had I not patience beyond mortal man

Injurious Queen! what wert thou :-Goes she not,
Obedient to heaven's holy oracle,
A voluntary vi&im to preserve

Thy wretched being ?-Seize her!
Deianira,

Of! forbear!
Horrible wretch!
Tbeftor.

What dreadful profanation !
Rețire, before th' offended goddess-
Alcander.

Speak;
Pronounce the sentence; Conon bids thee speak!
Demophon, He does; and wakes each agonizing nerve

Within a father's breaft! But to behold
Thạc spectacle !--yet Conon, yet my fon-

If one most die !-Sound, found for sacrifice !
Deianira. No, dare not, as you're men!' it were a found

To start the powers of heaven!! clasp thy knees !
Mercy ! oh, mercy on the most forlorn,
Unfortunate of womankind! No more
My frantic rage upbraids thee: by the name
Revered of parent, spare, ob spare my child!
And if you must have blood, take mine for hers!

And freely shall it flow.
Macaria.

The impious hand,
Raised 'gainst her reverend age, is raised 'gainst heaven!

It braves the thunderer's bolts !
Drianira.

Regard not her,
Unnatural child! he feels not for the mother
Who gave the life the scorns; regard not her ;
Thee I again implore; in bitterness
Of bursting anguilh, clasp thy knees again,
Nay, turn notwin the terror of thine eye
A drop I fee, that will not be restrained;
Tis nature pleading from my heart to thine !
Oh, hear her terrible, her tender cry!

And here the poignard plunge!
Macaria.

Tempt not, rash Kinga
Tempt not the gods !-on thee, on all thy race,
A mother's innocent blood will cry for blood !
Macaria is the victim! speak the word
Which the gods fpoke. Now, from yon opening heaven,
They all look down on this tremendous scene !
They view this agonizing heart that heaves
To meet the blow! then, by that heaven, I charge you,

Plunge here the poignard !
Demopbon.

Sound to sacrifice,
And lead Macaria forth.
Deianira.

Barbarian! no-
Thou falt not force her from me; thus entwined,
We'll die together in each other's arms,
Mother and daughter.
