Mechanics, servants, farmers, and so forth,
Are copy-paper, of inferior worth;
Less priz'd, more useful, for your desk decreed,
free to all pens, and prompt at ev'ry need.

The wretch whom av'rice bids to pinch and spare,
Starve, cheat, and pilfer, to enrich an heir.
Is coarse brown-paper ; such as pedlers choose
To wrap up wares, which better men will use.

Take next the miser's contrast, who destroys Health, fame, and fortune, in a round of joys. Will any paper match himn? Yes, throughout, He's a true sinking-paper, past all doubt.

The retail politician's anxious thought
Deems this side always right, and that stark nought;
He foams with censure; with applause he raves--
A dupe to rumours, and a tool of knaves;
He'll want no type his weakness to proclaim,
While such a thing as fools-cap has a name.

The hasty gentleman, whose blood runs high,
Who picks a quarrel, if you step awry,
Who can't a jest, or hint, or look endure :
What's he? What? Touch-paper to be sure.

What are our poets, take them as they fall Good, bad, rich. poor, much read, not read at all? Them and their works in the same class you'll find : They are the mere waste-paper of mankind.

Observe the maiden, innocently sweet,
She's fair white-paper, an unsullied sheet;
On which the happy man, whom fate ordains,
May write his name, and take her for his pains.

One instance more, and only one I'll bring;
Tis the great man who scorns a little thing,
Whose thoughts, whose deeds, whose maxims are

his own,
Form'd on the feelings of his heart alone :
True genuine royal-paper is his breast :
Of all yhe kinds most precious, purest, best.

ON THE ART OF SWIMMING,

WN ANSWER TO SOME INQUIRIES OF M. DUBOURG *

ON THE SUBJECT. I am apprehensive that I shall not be able to find leisure for making all the disquisitions and experiinents which would be desirable on this subjeci. I must, therefore, content nyself with a few remarks.

The specific gravity of some human bodies, in comparison to that of water, has been examined by M. Robinson, in our Philosophical Transactions, volume 50, page 30, for the year 1757. He asserts, that fat persons with small bones float most easily upon waler.

* The diving bell is accurately described in our Transactions.

When I was a boy, I made two oval pallets, each about ten inches long, and six broad, with a hole for the thumb, in order to retain it fast in the palm of iny hand. They much resemble a painter's pallets. In swimming, I pushed the edges of these for. ward, and I struok the water with their flat surfaces as I drew then back: I remember I swam faster by mcans of these pallets, but they fatigued my wrists. I also fitted to the soles of my feet a kind of sandals; but I was not satisfied with them, because I observed that the stroke is partly given by the ir side of the feet and the ancles, and not entirely with the soles of the feet.

We have here waistcoats for swimming, which are made of double sail-cloth, with small pieces of cork quilted in between them.

I know nothing of the scaphandre of M. de la Chapelle.

I know by experience, that it is a great comfort to a swimmer, who has a considerable distance to go, to turn himself sometimes on his back, and to vary in other respects the means of procuring a progressive motion.

* Translator of Dr. Franklin's Works into French.

When he is seized with the cramp in the leg, the method of driving it away is to give to the parts affected a sudden, vigorous and violent shock; which he may do in the air, as he swims on his back.

During the great heats of summer, there is no danger in bathing, however warm we may be, in rivers which have been thoroughly warmed by the sun. But to throw one's self into cold spring water, when the body has been hcated by exercise in the sun, is an imprudence which may prove fatal. I once knew an instance of four young men, who, having worked at harvest in the heat of the day, with a view of refreshing themselves, plunged into a spring of cold water: two died upon the spot, a third the next morning, and the fourth recovered with great difficul. ty. A copious draught of cold water, in similar circumstances, is frequently attended with the same effect in North America.

The exercise of swimming is one of the most healthy and agreeable in the world. After having swam for an hour or two in the evening, one sleeps coolly the whole night, even during the most ardent heat of summer. Perhaps the pores being cleansed, the insensible perspiration increases, and occasions this coolness. It is certain, that much swimming is the means of stopping a diarrhea, and even of producing a constipation. With respect to those wno do not know how to swim, or who are affected with a diarrhea at a season which does not perinit them to use that exercise, a warm bath, by cleansing and putrifying the skin, is found very salutary, and often effects a radical cure. I speak frora my own experience, frequently repeated, and that of others, to whom I have recommended this.

You will not be displeased if I conclude these basty remarks by informing you, that as the ordinary method of swimming is reduced to the act of rowing with the arms and legs, and is consequently a laborious and fatiguing operation when the space of water to be crossed is considerable; there is a method in which a swimmer may pass to great distances with much facility, by means of a sail. This discovery I

fortunately made by accident, and in the following manner :

When I was a boy, I amused myself one day with flying a paper kite; and, approaching the back of a pond, which was near a mile.broad, I tied the string to a stake, and the kite ascended to a very considera ble height above the pond, while I was swimming. In a little time, being desirous of amusing myself with iny kite, and enjoying at the same time the pleasure of swimming, I returned, and loosing from the stake the string with the little stick which was fastened to it, went again into the water, where I found, that, lying on my back, and holding the stick in my hands, I was drawn along the surface of the water in a very agreeable manner. Having then engaged another boy to sarry my clothes round the pond, to a place which I pointed out to him, on the other side, I began to cross the pond with my kite, which carried me quite over without the least fatigue, and with the greatest pleasure imaginable. I was only obliged occasionally to halt a little in my course, and resist its progress, when it appeared that, by following too quick, I lowered the kite too much; by doing which occasionally I made it rise again. I have never since that time practised this singular mode of swimming, though I think it not impossible to cross in this manner from Dover to Calais. The packet-boat, how. ever, is still preferrable.

NEW MODE OF BATHING.

EXTRACTS OF LETTERS TO M. DUBOURG.

London, July 28, 1768. I GREATLY approve the epithet which you give, in your letter of the 8th of June, to the new method of Treating the small-pox, which you call the tonic on bracing method; L.will take occasion, from it, te mention a practice to which I have accustomed ms.

self. You know the cold bath has long been in vogue

here as a tonic: but the shock of the cold water hath í always appeared to me, generally speaking, as too | violent, and I have found it much more agreeable to my constitution to bathe in another element- I mean cold air. With this view I rise early almost every morning, and sit in my chamber without any clothes whatever, half an hour or an hour, according to the season, either reading or writing. This practice is not in the least painful, but on the contrary, agreeable; and if I return to bed afterwards, before I dress myself, as it sometimes happens, I make a supple. ment to my night's rest of one or two hours of the most pleasing sleep that can be imagined. I find no ill consequences whatever resulting from it, and that at least it does not injure my health, if it does not in fact contribute to its preservation. I shall therefore call it a bracing, or tonic bath.

March 10, 1773. I SHAI:L not attempt to explain why damp clothes occasion colds, rather than wet ones, because I doubt the fact; I imagine that neither the one nor the other contribute to this effect, and that the causes of cold are totally independent of wet, and even of cold. I propose writing a short paper on this subject, the first moment of leisure I have at my disposal. In the mean time, I can only say, that having some suspicions that the common notion, which attributes to cold the property of stojiping the pores and obstructing perspiration, was ill-founded, I engaged a young physician, who is making soine experiments with Sanctorius's balance, to estimate the different proportions of his perspiration, when remaining one hour quite naked, and another warmly clothed. He pursued the experiment in this alternate man. per for eight hours successively, and found his per

piration almost double during those hours in which -- se svas naked.
