THE PASHA AND THE DERVISE.*

When a sage leaves his shop and on politics doting,
Exchanges CLOTH PATTERNS for plans of REFORM;
When preachers hold forth on the pleasures of voting,
And roar, how delightfully calm is a storm!

Are they MAD? mad enough-see their frothy condition,
E'en the simple go mad when they're bit by AMBITION.
A Turkish Pasha in a whimsical mood,

Took a casket of gold full of jewelry fair,
And addressing a Dervise thrice solemnly good,
And wishing to make the grim animal stare,
"This casket," he cried, with extravagant mirth,
"You must give to the greatest of fools upon earth."
Sedately the Dervise observed the command,
And carefully went the gems' owner to find;
Great fools in abundance he found in the land,

But to each of them gravely he said in his mind, "Thou art a great goose, my good friend, I allow, But perhaps I may yet find a greater than thou."

O'er the regions adjoining he rambled in vain ;

All the land of the Tartars he wandered around,
And then to the Bosphorus cross'd he the main,

Where a people half frantic with terror he found;
With surprise he regarded the mob so delighted,
And with more when an Iman the reason recited.

With a bowstring the sultan has graciously sent
His vizier to take a short message to heaven;
These affairs give the faithful amazing content,
And oft this content by the sultan is given.
"What—often?" the sage with astonishment cried,
"Of late VERY often," the Iman replied.

This piece requires but little more than an easy, lively mode of delivery. Care must, however, be taken that the tones of the several speakers differ from each other, as also from that of the narrator.

The Dervise went on, “Is a successor named ?” "O yes, with a form and magnificence meet, This man, "said the Iman, "I heard him proclaim'd, There, there, you may see him, he's now in the street." The Dervise beheld him, with wonder he saw,

In the newly made vizier, his friend the Pasha.

"You still have the casket?" the Vizier began,

For well the grim face of the Dervise he kenn'd; Said the Dervise, "In vain long I sought for the man, For whom you design'd it-my search has its end; The jewels belong to no mortal but you,

They are YOURS, mighty Vizier, accept them-ADIEU."

GLOSSARY

OF

SCIENTIFIC TERMS.

Absorption, a sucking up, a term in Chemistry, used when a gas loses its properties by combination.

Accelerated Motion, or Acceleration, is that which receives fresh accessions of velocity; this particularly refers to the falling of heavy bodies towards the centre of the earth. Gravitation is now generally acknowledged to be the immediate cause of the acceleration of bodies.

Achromatic, a term applied to Telescopes contrived to remedy aberrations and colours. These were first invented by Mr. John Dolland. Acids, are those substances which produce a sour taste, probably caused by the peculiar shape of their particles. Acids are known by their changing vegetable blue colours, as syrup of violets, into red; They unite with earths, alkalies, and metallic oxydes, forming numerous salts.

Acoustics, the doctrine of hearing and sound. See page 47.

Adhesion, a species of union that takes place between the surfaces of

bodies this must not be confounded with Cohesion. Adhesion implies an union to a certain point between two substances either of similar or dissimilar kinds; Cohesion that which retains the component particles of the same mass.

Aeroliths, certain stones which occasionally fall from the atmosphere. See page 54.

Aerology, the science of the air as to its properties.

Aerostation, the art of ballooning or navigating in the air.

Affinity, an inclination which certain bodies have to combine chemically. See page 13.

Air-gun, an instrument to propel bullets by means of the air. See page 38.

Air-pump, a pneumatic machine for exhausting the air. See page 36. Alembic, a vessel used in Chemistry for distillation.

Alcohol, highly rectified spirits of wine.

Alkalies, peculiar substances which have a caustic taste, and a strong tendency to combine with acids, and thus form various salts. They change the blue juices of vegetables to a green, and the yellow to a brown.

Alluvial, "Deposition," soil formed by the destruction of mountains

through the agency of water.

Aluminum, the metallic base of Alumina or common clay.

Amalgam, a combination of mercury with another metal.

Ammonia, the volatile alkali. See page 72.

Analysis, the resolution of any substance into its component parts. Anemometer, an instrument for measuring the force of the wind. For Meteorological instruments, see page 56.

Antimony, a brilliant brittle metal of a white colour. See page 81.¦ Aquafortis, another term for "Nitric Acid."

Aqua-regia, or "Nitro-muriatic acid," a mixture of nitric and muriatic acid, in the proportion of two parts of the former to one of the latter : this will alone dissolve gold.

Areometry, a term applied to the science of measuring the density and gravity of fluids.

Arsenic, a metal usually found in combination with sulphur; when reduced to a metallic state it is of a brilliant colour, and at the same time the most brittle and the softest of metals. It is extremely poi

sonous.

Atmometer, an instrument contrived for measuring the quantity of exhalation in a given time..

Atmosphere, that invisible fluid that surrounds our earth. It received its name from the Greeks, in consequence of the vapours which are continually mixing with it. See page 34.

Atomic Motion, a supposed rapid motion of the atoms of bodies which produces heat.

Attraction, a term used to imply that power by which all bodies have a mutual tendency towards each other. See page 11.

Aurora Borealis, sometimes seen in the northern part of the heavens. See page 55.

Azote, the atmospheric air deprived of its oxygen. It was first discovered in 1772, by Dr. Rutherford, of Edinburgh, and its properties ascertained by Priestly and Cavendish. See page 70.

Balloon, a term applied to a chemical receiver of a spherical shape, also to a well known body used for aerostation.

Barium, a recently discovered metal, the base of Barytes,

Barometer, an instrument for ascertaining the weight of the atmosphere. See page 39.

Barytes, an earth usually found in combination with an acid, as the Sulphate and Carbonate of Barytes. It received its name from its weight, being the heaviest of all the earths. It is a violent poison. Base, a chemical term applied to denote the earth, the alkali or the metal which is combined with an acid to form a salt. Battery, "Electrical and Galvanic." See pages 60 and 63. Bismuth, a metal of a white reddish colour, rather hard, but neither malleable nor ductile. The oxide of this metal was sometime since used in medicine; a preparation of it is occasionally used in cosmetics.

Boiling,-Theory explained. See page 42.,
