he relapfed into his former ftate of infenfibility. We were obliged to open the windows and doors immediately, in order to obtain the greatest degree of cold poffible, and renew the projection of water, which we fortunately found at hand. Three hours more were employed in this exercife; and between eight and nine o'clock in the evening the fubject began to cry out with violence, and was feized with a univerfal trembling.

I now conducted myself as in the former cafes, and ordered him to be put to bed.

I vifited him about half past ten o'clock in the evening, I found him perfectly fenfible, but his belly was diftended, and his body was feized with fhiverings at intervals. I ordered a glyfter to be applied, and a ptifan of chicken broth with nitre, to be given him, and alfo the vulnerary mixture, with the liquor mineralis Hoffmanni. Thefe medicines having appeafed the latter fymptoms, I learned the next morning that he had paffed a good night. The pulle was become more regular, and the pain in the head lefs, as alfo the hiverings, and there only remained a fenfation of fatigue, and a small diftention of the abdomen, occafioned by the wind.

The fourth day our patient finding himself radically cured by the continuance of proper remedies, determined to go to the foot of the altar, and return thanks to God for preferving him from being interred alive; a miferable event, which would indubitably have taken place, had it not been for the application of this efficacious remedy!

The following Cafe, tranflated from the French, and inferted in the Reports of the Humane Society, cannot be too extenfively published, as it proves the great Danger, and even Inhumanity, of immediately abandoning new-born Infants when apparently dead, inftead of affiduonfly perfevering in the Trial of every Method that may reftore them to Life.

PUPIL in Midwifry in

A Manheim, being fent for to Lampertheim on Good Friday laft, to a woman in labour, found her in a very weak ftate in confequence of an hæmorrhage of 15 days continuance. He delivered her of a boy perfectly formed, but who, though all the means ufual in fuch cafes were tried, gave no figns of life. Fortunately the practitioner recollected, that when he had feparated the funis umbilicalis, its artery was filled with blood, from which he concluded, that the death of the child was not occafioned by the mother's hæmorrhage; for when that is the cafe, the umbilical artery is generally empty and flaccid. This confideration encouraged him to try the following experiment.

Having placed the child in a bath of warm wine, he applied his mouth to that of the patient, and blew into it, clofing the noftrils with the right hand, that the breath might be impelled into the trachea, while, with his left hand, he rubbed the abdomen; by these means producing a kind of artificial refpiration. He continued this operation during the space of balf an hour, without perceiving any effect, except that the colour of

the

of the chimney, and immediately underneath it or a fmall perforation made in the wall in any other convenient manner; the one end of which should communicate with the external air, and the other communicate with the chamber in any place near the grate, and as low down as poffible, through which a conftant fupply of air would be adminiftered to the fire, without the fmalleft inconvenience or trouble.

a

If this were practifed, doors and windows might with fafety be made much closer than ufual, and our apartments rendered equally warm and comfortable, with much fmaller quantity of fuel than we ufe at prefent. For as the fire, in the ordinary mode of conftructing chambers, is kept alive by a conftant fucceffion of cold air from the doors, windows, and other crannies of the room, rufhing towards the chimney in all directions, the air of the room, which, if not cooled by this means, would be quickly heated to a great degree, is conftantly kept cold, in fpite of the strong heat of a blazing fire; which, at the fame time that it fcorches the parts of our body that are most exposed to it, does not warm the parts that are turned from it; and we experience at the fame time a burning heat and piercing cold, which is often productive of the most difagreeable effects. But if the fire were fupplied with air in the manner abovementioned, there would be lefs air drawn in through the crannies of the room, fo that what was within would be foon warmed, and continue long fo, even with a small degree of heat.

However improper this might be for people in perfect health, it might furely be of great ufe for VOL. XX.

those who are in a weakly habit of body; efpecially if care were taken to carry off the foul air, by having a small tube leading from the upper part of the room to the top of the houfe, through which the air that had been rendered noxious by the fmoke of candles, or perfpiration, would be conveyed away, and a fucceffion of fresh air admitted from the tube near the fire-place to fupply that want.

If any one should think of adopting this fpecies of refinement, it is proper he fhould be warned of the inconveniencies that may attend it, as well from the benefits that may refult from it. I thall therefore be excufed for pointing thefe out on this occafion with fome degree of precifion.

Perhaps nothing contributes fo much towards preferving the health of fedentary and reclufe perfons, as the fires that are ufually burnt in our apartments; as they perform the part of a perpetual ventilator, which helps to carry off the foul air, that is continually generating by the breath of the company, and burning of the candles; which would foon be accumulated in fuch quantities as to become extremely noxious, were it not for the aid that this affords us in cold climates,

On this account open fires, which are much more chearful, are also more conducive to health, than concealed ftoves, which are employed in fome cold countries.We ought therefore to adhere to our own old fashion, and not be in too much hate to imitate our frugal neighbours in this particu lar.

For the fame reafon I would by no means advise, that the method above defcribed of feeding the fire with fresh air, fhould be adopted

I

without

without proper precautions. For fhould our doors and windows be made very clofe, and thefe pipes for admitting air be left open, the fresh air would be fo readily admitted by that means, as to keep the air of the room in æquilibrio with the external atmosphere, fo that little or none would be preffed in through the crannies at which it at prefent enters; and the perpetual ventilation would thus be ftopped, and the foul air be continually retained in the room; which might thus indeed be heated at a much smaller expence, and more equally, than at prefent, but it would be at the fame time lefs healthful to the inhabitants.

It would, therefore, by no means be fafe to introduce the cool air by this contrivance, without at the fame time opening a vent-hole in the top of the room, by which the foul air might be carried out of the apartment. This might be done by means of a small tube epening into the room, either in or near the cieling; which might either be carried to the top of the building, or be made to communicate with the external air by a fmall perforation through the wall at the roof of the room, by means of either of which a proper circulation would be established, and

the foul air be carried off.

For the fire would no fooner have warmed any particles of air within the room, than thefe would be greatly expanded, and rife immediately upwards, fo as to fill the higher parts of the room with rarefied air;-and as other particles would be fuccellively heated and rarefied in their turn, by their expanfive force they would prefs upon the fides of the apartment in

every place, fo as to force the lighteft particles through the opening left for that purpofe in the top of the room, by which means the fouleft air would be gradually drawn off, without defcending again into the lower regions. to the annoyance of the company.

By attending to thefe circumftances, it will appear fufficiently obvious, that a room which has fuch a ventilator within itfelf in the roof, will be more sweet and wholefome than one in the ordinary fashion. For although the fre ventilates the under part of the room well enough; yet fuch particles of air as are rarified by its ac tion at fuch a distance from it, as to be buoyed upwards beyond the reach of the chimney, when they once rife above the top of the mantle will be carried directly to the top of the room, where they must remain clogged with the foul vapours; having no outlet through which they can iffue forth to the open air.

To cure this evil, a fpecies of ventilator has been lately contrived, by fitting a fmall circular wheel of metal into one of the upper panes of the highest window ;-which is certainly of fome utility, unless where it is attended with other inconveniencies, which now require to be pointed out.

If a vent-hole is made in the roof of the room, through which the rarefied air may be readily emitted, it must follow, that as the air within the room is gradually heated, and thus carried off, fome cool fresh air muft infinuate itfelf into the room to fupply that deficiency, as well as to keep the fire alive; but if there is no vent for the heated air in the room but

through

through the pipe of the chimney, there will be lefs danger that the fmoke will be drawn from it into the apartments, than if there be another opening made for carrying off that heated air;-fo that any thing of this fort must have a tendency to diminish the draught of the chimney, and may on fome occafions produce fmoke, where it would not have appeared without it.

Every opening, therefore, of the fort here mentioned, ought to be fo contrived, as to admit of being fhut or opened at pleasure, fo as that a remedy may be at hand for this difeafe whenever it may be come troublesome.-But the wheelventilators above alluded to do not admit of this, and are on this account imperfect.

There is no neceffity for having that opening very large on any occafion, but it ought to be fo formed as to admit of being eafily contracted without being wholly fhut; which might be best effected by having the mouth of it covered with a fliding fhutter, like that on the end of a telescope, which might be closed or opened to any degree at pleasure.

But if this pipe in the upper part of the room will have fome tenlency in any cafe to produce fmoke, t will be rather in greater danger of occafioning this, if the fresh air s admitted to the fire by the pipes bove defcribed, than in the orlinary way. For as the room, as vell as the chimney, muft in this afe be in a great meafure fupplied vith fresh air from thefe tubes, here would be fome danger, that niffuing into the room it might raw fome fmoke along with it. This danger, however, it must be

acknowledged, is but very fmall, next to nothing,-as all the fresh air that would flow from thefe into the room would ifue at the under part next the hearth, where there should be no fmoke.-What fhould go once through the grate, could never be drawn from the chimney, unless by extreme imprudence in allowing too great an opening in the roof of the room.

It would be better, however, on all occations to obviate this inconvenience, fmall as it is, by the following contrivance, which would render our apartments more sweet, wholefome, equally warm in every part, and more agreeable upon the whole, than any other.

Let another opening be made in the cieling of the room, having a communication with a fmall pipe that should lead from thence either to the outfide of the wall, or to any other part of the building that might be judged more convenient ; where it fhould be bent, and conducted downwards, till it reached the ground; where it fhould be left open, to communicate with the external air.-In this fituation the cool external air would be forced in at the lower opening of the tube, and made to afcend into the apartment, in proportion to the quantity that escaped towards the higher regions by means of the ventilator. And as that weighty air would no fooner enter the room than it would tend towards the floor by its own natural gravity, it would gradually mix with the heated air in its defcent,-become in fome meafure warmed by that means, and equally equally difperied through the room, fo as flowly and imperceptibly to reach the candleg and the company in the room,
