MR. EDITOR,—Many months having passed away since I last addressed you, I have flattered myself, as most old men are apt to do on such occasions, that you might very possibly begin to feel some little inclination to hear from me once more. Know then, my good sir, that I am still in the land of the living, and have collected several "odds and ends" of matters and things in general, which you may use or not, for your "Messenger," as the fancy strikes you.

Among the rest, I will proceed to give you a new classification of the Animal Kingdom—at least so far as our own race is concerned; a classification formed upon principles materially different from those adopted by the great father of Natural History—Linnæus, who you know, classed us with whales and bats, under the general term, Mammalia! Now, I have always thought this too bad—too degrading for the lords and masters (as we think ourselves) of all other animals on the face of the earth; and who deserve a distinct class to themselves, divided too into more orders than any other—nay, into separate orders for the two sexes. With much study, therefore, and not less labor, I have digested a system which assumes mental—instead of bodily distinctions, as much more certain and suitable guides in our researches. This may be applied without either stripping or partially exposing the person, as father Linnæus' plan would compel us to do, whenever we were at a loss to ascertain (no unfrequent occurrence by the way, in these days) whether the object before us was really one of the Mammalia class or not: for such are the marvellous, ever-varying metamorphoses wrought by modern fashions in the exteriors of our race, that the nicest observers among us would be entirely "at fault" on many occasions, to tell whether it was fish, flesh, or fowl that they saw. My plan, therefore, has at least one material advantage over the other; and it is quite sufficient, I hope, very soon to carry all votes in its favor.

With whales and bats we shall no longer be classed!—if your old friend can possibly help it; and he is not a little confident of his powers to do so; for he believes he can demonstrate that there is not a greater difference between the form, size and habits of the bats and whales themselves, than he can point out between the manners, customs, pursuits, and bodily and mental endowments of the different orders of mankind; and, therefore, ex necessitate rei, there should be a classification different from any yet made. The honor of this discovery, I here beg you to witness, that I claim for myself.

Before I proceed farther, I will respectfully suggest a new definition of man himself; as all heretofore attempted have been found defective. The Greeks, for example, called him "Anthropos"—an animal that turns his eyes upwards; forgetting (as it would seem) that all domestic fowls, especially turkeys, ducks and geese, frequently do the same thing; although it must be admitted, that the act in them is always accompanied by a certain twist of the head, such as man himself generally practices when he means to look particularly astute. One of their greatest philosophers—the illustrious Plato—perceiving the incorrectness of this definition, attempted another, and defined man to be "a two legged animal without feathers:" but this very inadequate description was soon "blown sky high" by the old cynic Diogenes, who, having picked a cock quite clean of his plumage, threw him into Plato's school, crying out at the same time, "Behold Plato's man!" True, this is an old story; but none the worse for that. This was such "a settler,"—to borrow a pugilistic term—as completely to discourage, for a long time, all farther attempts to succeed in this very difficult task; nor indeed, do I recollect, from that day to the present, any now worth mentioning. "The grand march of mind," however, has become of late years, so astoundingly rapid, and so many things heretofore pronounced to be unknowable, have been made as plain as the nose on our faces, that Man himself—the great discoverer of all these wonders, should no longer be suffered (if his own powers can prevent it) to be consorted, as he has so long been, with a class of living beings so vastly inferior to himself. To rescue him therefore from this degradation, shall be my humble task, since it is one of those attempts wherein—even to fail—must acquire some small share of glory.

I will define him then, to be A self-loving, self-destroying animal, and will maintain the correctness and perfectly exclusive character of the definition, against all impugners or objectors, until some one of them can point out to me among all the living beings on the face of the earth, either any beast, bird, fish, reptile, insect, or animalcula, that is distinguished by these very opposite and directly contradictory qualities. Man alone possesses—man alone displays them both; and is consequently distinguished from all the rest of animated nature in a way that gives him an indisputable right to a class of his own.

I will next proceed to enumerate the different orders into which this most wonderful class is divided. The females, God bless them, being entitled, by immemorial usage, to the first rank, shall receive the first notice; and I will rank in the first order all those who have unquestionable claims to pre-eminence.

Order 1st. The Loveables.—This order is very numerous, and forms by far the most important body in every community, being distinguished by all the qualities and endowments—both physical and intellectual—which can render our present state of existence most desirable—most happy. Their beauties charm—their virtues adorn every walk of life. All that is endearing in love and affection—either filial, conjugal, or parental: all that is soothing and consolatory in affliction; all that can best alleviate distress, cheer poverty, or mitigate anguish: every thing most disinterested, most enduring, most self-sacrificing in friendship—most exemplary in the performance of duty: all which is most delightful in mental intercourse, most attractive and permanently engaging in domestic life: in short, every thing that can best contribute to human happiness in this world, must be ascribed, either directly or indirectly, much more to their influence than to all other temporal causes put together; and would the rest of their sex only follow their admirable example, this wretched world of ours would soon become a secondary heaven.

Order 2d. The Conclamantes, which, for the benefit of your more English readers, I will remark, is a Latin word, meaning—those who clamor together. They possess two qualities or traits in common with certain birds, such as rooks, crows and blackbirds, that is, they are gregarious and marvellously noisy; for whenever they collect together, there is such a simultaneous and apparently causeless chattering in the highest key of their voices, as none could believe but those who have had the good or ill fortune (I will not say which) to hear it. But there is this marked characteristic difference. The latter utter sounds significant of sense, and perfectly intelligible, often very sprightly and agreeable too, when you can meet them one at a time; nor is juxta-position at all necessary to their being heard; for you will always be in ear-shot of them, although separated by the entire length or breadth of the largest entertaining-room any where to be found. Their proper element—the one wherein they shine, or rather sound most—is the atmosphere of a "sware-ree" party, or a squeeze: but as to the particular purpose for which Nature designed them, I must e'en plead ignorance; not, my good sir, that I would have you for one moment to suppose, that I mean any invidious insinuation by this excuse.

Order 3d. The Ineffables.—I almost despair of finding language to describe—even the general appearance of this order, much less those mental peculiarities by which they are to be distinguished from the rest of their sex. But I must at least strive to redeem my pledge, and therefore proceed to state, that they rarely ever seem to be more than half alive: that their countenances always indicate (or are designed to do so) a languor of body scarcely bearable, and the most touching—the most exquisite sensibility of soul; that even the most balmy breezes of spring, should they accidentally find access to them, would visit them much too roughly: that to speak above a low murmur would almost be agony, and to eat such gross food as ordinary mortals feed upon would be certain death. As to their voices, I am utterly hopeless of giving the faintest idea, unless permitted both to resort to supposition and to borrow Nic Bottom's most felicitous epithet of "a sucking dove." You have only to imagine such a thing, (it is no greater stretch of fancy than writers often call upon us to make) and then to imagine what kind of tones "a sucking-dove" would elicit; and you will certainly have quite as good an idea of the voice of an Ineffable as you could possibly have, without actually hearing it. No comparison drawn from any familiar sounds can give the faintest idea of it, for it is unique and sui generis. This order serves the admirable moral purpose of continually teaching, in the best practicable manner, the virtue of patience to all—who have anything to do with it.

Order 4th. The Tongue-tied, or Monosyllabic.—This order can scarcely be described—unless by negations; for they say little or nothing themselves, and, therefore, but little or nothing can be said of them; unless it were in the Yankee mode of guessing; which, to say the least of it, would be rather unbecoming in so scientific a work as I design mine to be. The famous Logadian Art of extracting sun-beams from cucumbers would be quite easy in practice compared with the art of extracting anything from these good souls beyond a "yes" or a "no," as all have found to their cost, who ever tried to keep up the ball of conversation among them; the labor of Sysiphus was child's play to it. They serve however one highly useful purpose, and that is, to furnish a perpetual refutation of the base slander which one of the old English poets has uttered against the whole sex in these often quoted lines—
