The bishop of Mentz was a wealthy prince, Wealthy and proud was he; He had all that was worth a wish on earth— But he had not charitie! He would stretch put his empty hands to bless, Or lift them both to pray; But alack! to lighten man's distress, They moved no other way. A famine came! but his heart was still As hard as his pride was high; And the starving poor but throng'd his door To curse him and to die. At length from the crowd rose a clamour so loud, That a cruel plot laid he; He open'd one of his granaries wide, And bade them enter free. In they rush'd—the maid and the sire. And the child that could barely run— Then he clos'd the barn, and set it on fire. And burnt them every one! And loud he laugh'd at each terrible shriek, And cried to his archer-train, "The merry mice!—how shrill they squeak!— They are fond of the bishop's grain!" But mark, what an awful judgment soon, On the cruel bishop fell; With so many mice his palace swarm'd, That in it he could not dwell. They gnaw'd the arras above and beneath, They eat each savoury dish up; And shortly their sacrilegious teeth Began to nibble the bishop! He flew to his castle of Ehrenfels, By the side of the Rhine so fair; But they found the road to his new abode, And came in legions there. He built him, in haste, a tower tall In the tide, for his better assurance; But they swam the river, and scal'd the wall, And worried him past endurance. One morning his skeleton there was seen, By a load of flesh the lighter; They had picked his bones uncommonly clean, And eaten his very mitre! Such was the end of the bishop of Mentz, And oft at the midnight hour, He comes in the shape of a fog so dense, And sits on his old "Mouse-Tower."

PRUSSIC ACID

(For the Mirror.)

The circumstance of Montgomery's recent suicide in Newgate, has led me to send you the following remarks upon the nature and properties of that most violent poison, Prussic acid, with which the unfortunate man terminated his existence.

Were we to consider the constituent parts and properties of the most common things we are in the habit of daily using, and their poisonous and destructive natures, we should recoil at the deadly potion, and shrink from the loathsome draught we are about to take. That which we consider the most delicious and exhilarating portion of our common beverage, porter, contains carbonic acid gas, commonly known by the "spirit," and which the poor miners dread with the utmost horror, like the Arabian does the destructive blast of the simoon. Oxalic acid, so much the fear of those accustomed to the medicine—Epsom salts, is made from that useful article, sugar, by uniting with it a smaller portion, more than it has naturally, of oxygen gas. The air we breathe contains a most deadly poison, called by chemists azotic gas, which, by its being mixed with what is called vital air, (oxygen gas,) becomes necessary to our existence, as much as the one (vital air or oxygen gas) would be prejudicial without the other; and Prussic acid, the most violent of all poisons, is contained in the common bitter-almond. But these most destructive substances are always found combined with others, which render them often perfectly harmless, and can be separated only by the skill of the chemist.

The Prussic acid (by some called hydrocyanic acid) is a liquid, extracted from vegetables, and contains one part of cyanogen and one part of hydrogen. It is extracted from the bitter-almond, (as has been stated,) peach-blossom, and the leaves of the laurocerasus. It may also be obtained from animal substances, although a vegetable acid. If lime be added to water, distilled from these substances, a Prussiate of lime is formed; when, if an acid solution of iron be added to this mixture, common Prussian blue (or Prussiate of iron) is precipitated. The acid may be obtained from Prussiate of potash, by making a strong solution of this salt, and then adding as much tartaric acid as will precipitate the potash, when the acid will be left in solution, which must be decanted and distilled.

Its properties are a pungent odour, very much resembling that of bitter-almonds, with a hot but sweetish taste, and extremely volatile. It contains azote, with which no other vegetable acid is combined; it is largely used in the manufacture of Prussian blue. It is the most violent of all poisons, and destroys animals by being applied to the skin only. It is stated by an able chemist, that a single drop applied to the tongue of a mastiff dog caused death so instantaneously, that it appeared to have been destroyed by lightning. One drop to the human frame destroys life in two minutes.

But when chemically combined with other substances, its power is in a great measure neutralized, and it becomes a valuable article, both to the chemist as a test, and to the physician as a medicine. The Prussiate of potash and iron will enable the chemist to discover nearly the whole of the metals when in solution, by the colours its combination produces. Dr. Zollekoffer says, that in intermittent fevers the Prussiate of iron is in its effects superior to Cinchona bark, and says it never disagrees with the stomach, or creates nausea even in the most irritable state, while bark is not unfrequently rejected; a patient will recover from the influence of intermitting and remitting fevers, in the generality of cases, in much less time than is usual in those cases in which bark is employed. S.S.T.
