The city itself is full of idle reports, scandalous papers, murmurings, and beggars. In short, all is division, hatred, and anarchy."

"Philadelphia, September 22, 1756. "Governor Denny arrived here the 20th August. He was met at Trenton, Bristol, and all along the road, by every foe to Mr. Morris. Never was gentleman so escorted! Assemblymen, sheriffs, militiamen, associates, tag rag and bob-tail, lined the way from the widow Amos's* to the city. All more out of pique to our former,† than compliment to our present governor."

"Since my last to you, we have proved many anxious moments: seen the defeat of general Braddock, and the remainder of his army, under colonel Dunbar, flying to the city. This, after a month's stay with us, was ordered to Albany. The Indian s in our interest, deserting us and joining the French, and committing the most horrid massacres and waste on our frontiers. At first, to encourage their mischiefs, the French had promised the Indians, for every English scalp, a reward of five pistoles. But so overstocked has been this inhuman market, that the price has since fallen to a shilling, even to a dram of brandy."

"Philadelphia, January 26, 1759. "The present governor (Denny) is the strangest composition of a gentleman I ever knew. Haughty without spirit, polite without manners, and learned without knowledge: With respect to business, always at home, yet never to be spoken with. In the morning for the proprietaries, at noon of no party, and at night, plump for the assembly. In short, my dear sir, all is going wrong, and if long suffered, will be irretrievable.

"At Lancaster one morning, he diverted a mixed company with a ludicrous picture of your family, an adept at this kind of painting. He represented a coach and six, in which sat your father asleep, and your uncle in full spirits: six attendant Quakers were behind, and Ferdinand Paris was seated on the box as their coachman, driving like the devil. On the way, a party of Indians spring from the covert and scalp two of the quakers, the others calmly saying," who would have thought it!" Your uncle entreats Ferdinand not to drive so fast, who replies, " damn you but I will." Your father, regardless of the driver, and ignorant of the accident, with his mouth open, continues his nap to the end of the journey."

THE USEFUL ARTS.-FOR THE PORT FOLIO.

MR. OLDSCHOOL,

THE following practical directions for clearing vinegar, which I have translated from the Annales de Chymie, vol. 79, p. 71, for July, 1811, appear to me so likely to be useful, that I think you will be glad to insert them in The Port Folio.

On the Decoloration of Vinegar: with a new process for taking away the colour of that acid, and other vegetable liquids,

It appears from the correspondence that governor Denny was recognised by the proprietaries to be a very bad servant. He had been recommended to the station by the duke of Cumberland, who gives him up, and concurs in the proprie. ty of his removal.

by means of animal charcoal. By M. Figuiers, professor of chemistry, at the school of pharmacy, at Montpelier. Read at the sitting of 27th December, 1810, of the Society of Sciences and Belles Lettres.

Of all the vegetable acids, vinegar is doubtless the earliest known and the most useful. It is made cheaply, easily, in every country, in large or in small quantities; hence its use has been greatly extended, in domestic economy and in the arts. It is a principal ingredient in several chemical and pharmaceutical preparations. The physician, the cook, the perfumer, the confectioner, alike use it. It forms one of the most considerable manufactures of France: hence the many attempts that have been made to bring to perfection the process of making it, of purifying it, and applying it to use.

Being occupied in a course of experiments to destroy the colour of vegetable liquids by means of charcoal, I hit upon a method of clearing vinegar, which, if I mistake not, will increase its uses and its value.

Vinegar of wine, is usually considered preferable to the other vinegars, and it is of this I now treat. It is either red or white, as it is made from red or white wine. The last is more prized, inasmuch as it contains less of the coloured extractive matter than red wine vinegar.

The common means employed to deprive it of colour, are the following:

1st. The whites of one or two eggs are beat up and mixed with a litre (61,028 cubic inches, or about a quart) of vinegar. The mixture is exposed to a boiling heat; the coagulated albumen carries down part of the colouring matter; the liquor is passed through filtering paper.

2dly. A large wine glass full of milk (un verre de lait) is poured into 5 or 6 quarts of hot vinegar, the mixture is stirred: the cheesy part of the milk precipitates much of the colouring matter the liquor is filtered.

3dly. The refuse of white grapes, after all the juice is pressed out, has also the property of clearing vinegar: it is used for this purpose, in a large way, at the manufacture of vinegar at Séte, from whence a great quantity of white or colourless vinc

gar is sent on to the north. For this purpose the marc or refuse of the wine press of white grapes is put into large wooden vessels, which are then filled up with vinegar. It is so left for several days. The vinegar is drawn off by a plug at the bottom, into another vessel containing another quantity of the marc of grapes; and this process is repeated till the vinegar comes away colourless.

By my process, which can be used either in the large or the small way, the vinegar is obtained still more free from colour, indeed as colourless as water.

I have found that animal charcoal is better for this purpose than the charcoal of vegetable substances. I shall not detail the many experiments that this research has cost me.

Take a quart (litre) of red wine vinegar, add to it, cold, 695 grains, troy (45 grammes) of the charcoal of bones, obtained as hereafter described. Stir it frequently. In twenty-four hours the vinegar will be seen in a state of commencing discoloration. In two or three days the process is finished. Filter it through paper, and it will be found to have lost neither its flavour, its odour, nor its acidity. In a large way, the animal. charcoal may be thrown into the cask of vinegar, and stirred about frequently. Nor need the quantity be in so large a proportion as above mentioned; one half the quantity will suffice, but it will require a longer time. No flavour is lost, nor is any superadded. I have kept this kind of mixture for months, without any diminution of acidity. By diminishing the proportion of charcoal, a light straw colour will still remain, which, to some, is desirable.

Vinegar thus discoloured, may be impregnated with any alcoholic solution of aroma, for the table or the toilet; and used for any purpose of pickling or preserving.

Wine may also be deprived of colour in the same way, and when so treated, its specific gravity is somewhat less. Still, on evaporation, it leaves a mucous residuum, which shows, that the animal charcoal acts principally on the colouring matter. This process may be used for brandy.

After the distillation of sulphuric æther, the acid employed remains in the retort; many attempts have been made to recover

it, for future processes. No experiment of mine has answered this purpose but that in which I employed animal charcoal. In the residuum of the distillation of æther, I added a quantity of water, equal in weight. I filtered it though paper, and then added to a quart of the filtered liquor, 50 grammes, or 772 troy grains of the charcoal of bones. After three days it was filtered, and it passed colourless. It was then concentrated by evaporation, and nearly the whole of the acid, originally employed, was recovered.

Tincture of turnsole, mixed with a few grammes of charred bones, is quickly deprived of its colour.

I prepare my bones thus: I take the most compact part of beef bone, or mutton bone; I break them, and fill a crucible, which I cover and lute carefully, except a small hole at the top. Thus prepared, I put it in a blacksmith's fire and heat it gradually to redness. When the flame produced by the combustion of the greasy matter of the bones is over, I partly stop the hole, and increase the fire; much carburetted and oxicarburetted gas escapes. I then stop the hole, and let the vessel cool. The charcoal is reduced to powder by trituration. The discolouring property of this charcoal depends much on the care taken in preparing it.

Ivory black, as well as bone black, also answers the purpose. By use they lose this property, which they regain on being strongly heated in a close vessel, but a little longer time is required to produce the effect.

All the experiments alluded to in this memoir, were repeated with the charcoal of wood, which produced but a slight effect. Hence, I conclude, that animal charcoal may, hereafter, be applied to many useful purposes in chemistry and the arts, to which vegetable charcoal is inedequate.

Vinegar, thus deprived of colour, contains a small quantity of acetite and phosphat of lime. These earthy salts produce no ill effect whatever on the animal economy, for we take them daily in much larger proportion, with our common food: but they may be previously separated, thus:

Pour on ivory or bone black, dilute muriatic acid; after twelve hours, add to it a quantity of water, filter and dry it. This
