CONCHOLOGY.

UNDER this title, or that of TESTACEOLOGY, naturalists have hitherto comprehended a systematick arrangement of shells, whether marine, fluviatile, or terrestrial it is the science by means of which that branch of natural history is distributed into genera and species. The title conchology has, however, been somewhat misapplied, having been used in a less extended sense than its etymological meaning implies; since conchylion does not express a shell only, but the molluscous animals, whose body is altogether protracted-merely partially covered with a shell, or possessing portions of shelly matter, concealed under its skin, or in its folds, to defend certain organs most liable to external injury from their exposed situation. Such of our earlier naturalists as merely studied an arrangement of shells, detached from their parent architect, (as was, in fact, the case with nearly all of them,) have in many cases, and should in every one, have designated their systems by the term Testaceology, which is more appropriate, as not admitting any perversion of the meaning they attached to it, and clearly expressing its derivation and object-Testa, the Latin word for a shell; and Logos, a Greek word, meaning a discourse or treatise on the subject to which that word is added when descriptive of a science. The Greek writers on natural history also used the term Ostracology, which has the same meaning, and is considered by

ing them; this, with very little exception, continued down to the period when the immortal Linnæus, who may be styled the father of systems, among others, formed one of Conchology, but, like his predecessors, it was based entirely on the form of the shell, and his genera composed from the characters it presented. This was done with considerable judgment, and many of his descriptions are extremely accurate, so far as regards external configuration, but in theory, this system is wholly artificial, and consequently bad. It is true he seems to have felt it so to a certain extent, since he has made some reference to the analogous animal which he imagined to have belonged to the shell; these he placed among his Zoophytes, but he still took no other guide than the form of the shell, and made but few inquiries with respect to the supposed inhabitant. The impulse given throughout Europe by his system, and that of several other eminent naturalists, led to an extended view of the subject; their attention became drawn to the anatomical investigation of the animals themselves; and the subject presented an interest never before experienced; accounts were published of the result of these inquiries, gradually producing a different method of viewing the classification of molluscous animals; and Pallas may be considered the head of this new school, as, in fact, it was from his Miscellanea Zoologica that the first germe of improvement was derived in the arrangement of shells, since grown into its present form, though as yet, in many respects, only in its infancy.

To persons who are collecting shells and forming cabinets of them only as beautiful objects of creation, the system of Linnæus may answer as well as any other, since they feel no interest in the scientifick arrangement of the species, or those won

But these, like all other tales conjured up credibly short space of time. Shall we then grudge by the magick wand of fancy, are more entertaining it a slender portion of our superfluous luxury, withthan true, and must be condemned in works whose out ascertaining, by actual examination and rational object should be to clothe facts in the simplest garb, reflection, that this little creature was not merely divesting them of the tinselled ornaments of fiction, ordained to devour our choicest fruit, but that it has which, though they may dazzle for a time, shortly also a duty to perform by consuming, in a far greater sink before the light of truth, and are rejected as proportion, other things in the vegetable world that worthless. Another serious evil arises from these would, without them, prevent the full completion of pretty nursery tales, that of casting a doubt upon the very object for which we ignorantly destroy a every other assertion, however well founded in principal agent. The well-established fact, that truth. eggs of these animals have been absolutely baked, during six months, under the scorching rays of a tropical sun, without destroying the germ of life, proves, could no other facts be adduced, that nature has vested in these creatures certain important uses and powers far beyond our short-sighted views; and it must lead a philosophical mind to conclude, that in this instance, as well as in many others equally remarkable, we stubbornly close our eyes to the good that is forced upon us. We think we hear it said, that in advocating the cause of snails, we have never had the mortification of seeing our ripe and delicately painted peaches disfigured by their hungry propensities. Be that as it may, we have also observed, that they, like ourselves, when no such treat presented itself, were content with humbler fare, and as industriously as voraciously consumed other objects, to us useless, or noxious as food, never deserting the purpose of their existence, though that end is not yet fully revealed to us. As an article of food, they are entitled to our consideration; for, though they form no part of our gastronomick delicacies, they nevertheless were considered such by the Roman gourmand; and even down to the pres ent day, snails form an important article of nourishment and commerce in Germany, France, Spain, Italy, Turkey, and the Levant. This digression leads to a conclusion, constantly to be drawn by every reflective mind, that from the colossus of bivalves (the Tridacna gigantea) whose inhabitant would satiate the "sharp-set appetites of a hundred men," down to the shell less than a grain of sand, each is endowed with similar mechanical powers and bodily faculties, adapted to its sphere of action in the place it is destined to occupy, the one and the other playing an equally important part in this crumbling theatre of mortality, and forming so many connecting links of the chain that binds together the invisible operations of nature under the directing wisdom of omnipotence.

An instance may here be adduced of the ease with which some of the interesting operations of nature can be witnessed in the portion of creation now under our consideration, and amply repay us for the trouble. It is afforded by the humble, persecuted, but most beautiful of our native molluscs, the snail, (Helix nemoralis,) the little creature we barbarously crush beneath our feet, considering it a common enemy to horticulture. When we examine its wonderful formation, its tenacity of life, its reproductive powers, an instructive lesson may be furnished to the conchological student, most satisfactorily explaining the growth of the vast proportion of similarly constructed shells in other genera, and enabling him to understand by actual observation, and the evidence of his own reason, some of nature's steps in this branch of her works; he may casily watch the various changes that take place from the slight viscous covering with which the animal's body, in the first instance, is coated, or, as it were, merely glazed, till that substance becomes a consistent firm shell, finally fashioned into a painted palace adapted to the form and use of its inhabitant. It needs no logick to prove, that wherever creatures are endowed with a long endurance of life and great reproductive powers, great purposes are assigned to them. The contemned snail does not, therefore, merit the ill treatment it constantly experiences from man; and if we for a moment reflect upon its good services, and overlook its bad ones, we are bound to confess the former greatly outweigh the latter. It is viewed as a destructive marauder in our trim gardens; but we forget that we have invited its inroads by placing, within a comparatively limited space, a choice selection of dainty food even to the pampered appetite of man, but altogether irresistible to a snail. In the open fields, or the widely expanded forest, this little creature performs useful purposes in conformity to the ends of its creation; one of the most important of which is that of assisting in consuming the exuberant productions of nature, which, without its operations, would encumber the surface of the globe, check the progress of future vegetation, and interrupt that perpetual harmony of system, which has wisely ordained that the extinction of life shall not be felt, but its devastations HAMBURGH is one of the most considerable of the become supplied by succeeding generations, each of free cities of Germany; it is situated about eighty their kind, whether vegetable or animal.

An arm of the Elbe enters the city from the east, and is there divided into a number of canals, which take various directions, till they unite, and join the Alster in the southern part of the city, where they form a deep harbour for ships, which communicates with the main branch of the river; and there is a large space enclosed by strong piles, where ships may lie in safety; which is called Rummelhaven.

The established religion in this city is the Lutheran, but complete toleration prevails. The manners of the inhabitans resemble those of the other mercantile cities of Germany or Holland; publick worship is regularly attended, industry is generally diffused, and good morals prevail. Foreigners have long been freely admitted to reside in the town; and the troubles of the French revolution brought to it individuals of different nations and characters, all of whom were allowed to remain as long as the publick tranquillity was not disturbed: hence the variCanals intersect the lower part of the city in all ous and sometimes contradictory accounts of the directions, and almost all the warehouses are built morality of the place.

The other articles of trade are very various, comprising flax, hemp, potash, tar, tobacco, wax, honey, hides, wool, woollen yarn, smoked and salt meat, mineral products, iron wares, in short all the products of the northeast of Germany, and a great part of those of the centre and south. This trade, like that in foreign goods, is carried on, partly on commission, partly for account of the Hamburgh merchants.
