pended there stood above the 150th degree. By placing several thermometers in different parts of the room we afterwards found, that the heat was a little greater in some places than in others; but that the whole difference never exceeded 20 deg. We continued in the room above 20 minutes, in which time the heat had risen about 12 deg., chiefly during the first part of our stay. Within an hour afterwards we went into this room again, without seeing any material difference, though the heat was considerably increased. Upon entering the room a third time, between five and six o'clock after dinner, we observed the quicksilver in our only remaining thermometer at 198 deg.; this great heat had so warped the ivory frames of our other thermometers, that every one of them was broken. We now staid in the room, all together, about 10 minutes; but find ing that the thermometer sunk very fast, it was agreed, that for the future only one person should go in at a time, and orders were given to raise the fire as much as possible. Soon afterwards Dr. Solander entered the room alone, and saw the thermometer at 210 deg., but, during three minutes that he staid there, it sunk to 196 deg. Another time, he found it almost five minutes before the heat was lessened from 210 deg., to 196 deg. Mr. Banks closed the whole, by going in when the thermometer stood above 211 deg. ; he remained seven minutes, in which time the quicksilver had sunk to 198 deg.; but cold air had been let into the room by a person who went in and came out again during Mr. Banks's stay. The air heated to these high degrees felt unpleasantly hot, but was very bearable. Our most uneasy feeling was a sense of scorching on the face and legs: our legs, particularly, suffered very much, by being exposed more fully than any other part to the body of the stove, heated red-hot by the fire within. Our respiration was not at all affected; it became neither quick nor laborious; the only difference was a want of that refreshing sensation which accompanies a full inspiration of cool air. Our time was so taken up with other observations, that we did not count our pulses by the watch: mine, to the best of my judgment by feeling it, beat at the rate of 100 pulsations in a minute, near the end of the first experiment; and Dr. Solanders made 92 pulsations in a minute,

soon after we had gone out of the heated room. Mr. Banks sweated profusely, but no one else: my shirt was only damp at the end of the experiment. But the most striking effects proceeded from our power of preserving our natural temperature. Being now in a situation in which our bodies bore a very different relation to the surrounding atmosphere from that to which we had been accustomed, every moment presented a new phenomenon. Whenever we breathed on a thermometer, the quicksilver sunk several degrees. Every expiration, particularly if made with any degree of violence, gave a very pleasant impression of coolness to our nostrils, scorched just before by the hot air rushing against them when we inspired. In the same manner our now cold breath agreeably cooled our fingers, whenever it reached them. Upon touching my side, it felt cold like a corpse; and yet the actual heat of my body, tried under my tongue, and by applying closely the thermometer to my skin, was 98 deg., about a degree higher than its ordinary temperature. When the heat of the air began to approach the highest degree which the apparatus was capable of producing, our bodies in the room prevented it from rising any higher; and, when it had been previously raised above that point, inevitably sunk it. Every experiment furnished proofs of this: towards the end of the first, the thermometer was stationary: in the second, it sunk a little during the short time we staid in the room in the third, it sunk so fast as to oblige us to determine that only one person should go in at a time; and Mr. Banks and Dr. Solander each found, that his single body was sufficient to sink the quicksilver very fast, when the room was brought nearly to its maximum of heat.

These experiments, therefore, prove in the clearest manner, that the body has a power of destroying heat. Το speak justly on this subject, we must call it a power of destroying a certain degree of heat communicated with certain quickness. Therefore, in estimating the heat which we are capable of resisting, it is necessary to take into consideration not only what degree of heat would be communicated to our bodies, if they possessed no resisting power, by the heated body, before the equilibrium of heat was effected; but also what time that heat

would take in passing from the heated body into our bodies. In consequence of this compound limitation of our resisting power, we bear very different degrees of heat in different mediums. The same person who felt no inconvenience from air heated to 211 deg. could not bear quicksilver at 120 deg. and could just bear rectified spirit of wine at 130 deg. that is, quicksilver heated to 120 deg. furnished, in a given time, more heat for the living powers to destroy, than spirits heated to 130 deg. or air to 211 deg. And we had, in the heated room where our experiments were made, a striking, though familiar instance of the same. All the pieces of metal there, even our watch-chains, felt so hot that we could scarcely bear to touch them for a moment, whilst the air, from which the metal had derived all its heat, was only unpleasant. The slowness with which air communicates its heat was further shown, in a remarkable manner, by the thermometers we brought with us into the room; none of which, at the end of twenty minutes, in the first experiment, had acquired the real heat of the air by several degrees. It might be supposed, that by an action so very dif

ferent from that to which we are accustomed, as destroying a large quantity of heat, instead of generating it, we must have been greatly disordered. And indeed we experienced some inconvenience; our hands shook very much, and we felt a considerable degree of languor and debility; I had also a noise and giddiness in my head. But it was only a small part of our bodies that excited the power of destroying heat with such a violent effort as seems necessary at first sight. Our clothes, contrived to guard us from cold, guarded us from the heat on the same principles. Underneath we were surrounded with an atmosphere of air, cooled on one side to 98 deg. by being in contact with our bodies, and on the other side heated very slowly, because woollen is such a bad conductor of heat. Accordingly I found, toward the end of the first experiment, that a thermometer put under my clothes, but not in contact with my skin, sunk down to 110 deg. On this principle it was that the animals, subjected by M. Tillet to the interesting experiments related in the "Memoirs of the Academy of Sciences" for the year 1764, bore the Oven so much better when they were

clothed, than when they were put in bare: the heat actually applied to the greatest part of their bodies was considerably less in the first case than in the last. As animals can destroy only a certain quantity of heat in a given time, so the time they can continue the full exertion of this destroying power seems to be also limited; which may be one reason why we can bear for a certain time, and much longer than can be necessary to fully heat the cuticle, a degree of heat which will at length prove intolerable. Probably both the power of destroying heat, and the time for which it can be exerted, may be increased, like most other faculties of the body, by frequent exercise. It might be partly on this principle, that, in M. Tillet's experiments, the girls, who had been used to attend the oven, bore, for ten minutes, an heat which would raise Fahrenheit's thermometer to 280 deg. In our experiments, however, not one of us thought he suffered the greatest degree of heat that he was able to support.

We find then, that Dr. Fordyce, Dr. Blagden, Dr. Solander, the honourable captain Phipps, sir Joseph Banks, to gether, bore the heat at 198 deg.; that Dr. Solander went into the room at 210, sir Joseph Banks at 211; and that M. Tillet's oven-girls bore a heat for ten minutes which would raise the thermometer to 280 deg., being 60 deg. higher than M. Chabert bore for ten

minutes at White Conduit-house. Recent experiments in England fully corroborate the experiments referred to; and, in short, an extension of our knowledge in philosophical works will outjuggle jugglers of every description.

FIGG, THE PRIZE FIGHTER.

the same for dinner: little enough, it must be confessed; but quite as much as the unremitting labour of a life of idleness can afford! Between the abovenamed hours, on the three first Sundays of this month, and the two last of the preceding, you may (weather willing) gladden your gaze with such a galaxy of beauty and fashion (I beg to be pardoned for the repetition, for fashion is beauty) as no other period or place, Almack's itself not excepted, can boast: for there is no denying that the fair rulers over this last-named rendezvous of the regular troops of bon ton are somewhat too recherchée in their requirements. The truth is, that though the said rulers will not for a moment hesitate to patronise the above proposition under its simple form, they entirely object to that subtle interpretation of it which their sons and nephews would introduce, and on which interpretation the sole essential difference between the two assemblies depends, In fact, at Almack's fashion is beauty; but at Kensington Gardens beauty and fashion are one. At any rate, those who have not been present at the latter place during the period above referred to, have not seen the finest sight (with one exception) that England has to offer.

Vauxhall Gardens, which open the first week in this month, are somewhat different from the above, it must be confessed. But they are unique in their way nevertheless. Seen in the darkness of noonday, as one passes by them on the top of the Portsmouth coach, they cut a sorry figure enough. But beneath the full meridian of midnight, what is like them, except some parts of the Arabian Nights' Entertainments? Now, after the first few nights, they begin to be in their glory, and are, on every successive gala, illuminated with "ten thousand additional lamps," and include all the particular attractions of every preceding gala since the beginning of time!

Now, on fine evenings, the sunshine finds (or rather loses) its way into the galleries of Summer theatres at whole price, and wonders where it has got to. Now, boarding-school boys, in the purlieus of Paddington and Mile End, employ the whole of the first week in writing home to their distant friends in Loudon a letter of not less than eight

lines, announcing that the "ensuing va cation will commence on the instant;" and occupy the remaining fortnight in trying to find out the unknown numerals with which the blank has been filled up.

Finally, now, during the first few days, you cannot walk the streets without waiting, at every crossing, for the passage of whole regiments of little boys in leather breeches, and little girls in white aprons, going to church to practise their annual anthem-singing, preparatory to that particular Thursday in this month, which is known all over the world of charity-schools by the name of "walking day;" when their little voices, ten thousand strong, are to utter forth sounds that shall dwell for ever in the hearts of their hearers. Those who have seen this sight, of all the charity children within the bills of mortality assembled beneath the dome of Saint Paul's, and heard the sounds of thanksgiving and adoration which they utter there, have seen and heard what is perhaps better calculated than anything human ever was, to convey to the ima gination a faint notion of what we expect to witness hereafter, when the hosts of heaven shall utter with one voice, hymns of adoration before the footstool of the Most High*.

TWILIGHT.

How fine to view the Sun's departing ray
Fling back a lingering lovely after-day;
The moon of summer glides serenely by,
And sheds a light enchantment o'er the sky.
These, sweetly mingling, pour upon the
sight

A pencilled shadowing, and a dewy light-
A softened day, a half unconscious night.
Alas too finely pure on earth to stay,
It faintly spots the hill, and dies away.

THE WATER FOUNTAIN.

It seems scasonable to introduce an engraving of a very appropriate ornament of a shop window, which will not surprise any one so much as the proprietor, who, whatever may be thought to the contrary, is wholly unknown to the editor of this work.

As a summer decoration, there is scarcely any thing prettier than this little fountain. Gilt fish on the edge

HOUSE OF GOD, NEWCASTLE. On the 10th of June, 1412, King Henry IV. granted his royal license to an hospital called the Maison de Dieu,

or "House of God," erected by Roger Thornton, on the Sandhill, Newcastle, for the purpose of providing certain persons with food and clothing. The building seems to have been completed in that year. Before it was pulled down in 1829, the "Merchant's Court" was established over it, and at this time a new building for the company of Free Merchants, &c., is erected on its site.

The son of the founder of the old
