СКАЧАТЬ so lavishly bestowed scarce can he extract a scanty subsistence, scarce can he render it subservient to his wants or his pleasures; and he who maintains that this world was made alone for man, might, amid such scenes, find room to doubt. The cui bono must at every step occur to his mind; he will soon discover that the tenants of so much luxuriance are reduced to a very scanty number, and these of the lowest order of animated creatures; birds, lizards, reptiles, insects, and a very few predaceous quadrupeds. The poet may select such scenes for the abodes of bliss, of happiness, and of mortal felicity; but the philosophic inquirer will look to countries of less flattering aspect for the more favourable existence and development, in the social state, of the mental faculties of the human race.

      We were now at liberty to employ our time agreeably to our respective inclinations. The surrounding forests and hills afforded endless enjoyment to those attached to natural history. They therefore claimed no ordinary share of my regard. Every day continued to add something to my little stock; while such is the salubrity of the climate, that no danger seemed to be apprehended from the most free and continual exposure even to the heat of a meridian sun, under circumstances of fatigue, exhaustion, and the greatest exertion; and to penetrate to any distance into the woods, or to ascend the steep and rugged sides of the hills, necessarily exposes one to such conditions. Compared with the botanical objects, the zoological are but scanty. Yet in this department we were able to effect the commencement of a collection. The most singular animal we as yet procured was the Galeopithecus variegatus, an animal covered with the softest fur; furnished with a broad expansion of the skin, extending from the head along the neck to the fore-feet, which are palmated; from thence to the hind-feet, also palmated, and from this to the extremity of the tail. By means of this membrane it is able, for a short distance, to support itself in the air. In the night-time it is active and lively; in the day, dull, lazy, sleepy, and annoyed at being disturbed. It has two pectoral mammæ. Those of the female are of considerable size. The voice is harsh, sharp, screaming, and disagreeable. It feeds on fruit, and would seem to be easily domesticated.

      In some points this singular animal has a strong affinity to the genus Lemur; but its elongated head, and comparatively small eyes, and more especially the want of incisorial teeth in the upper jaw, shew that it has been with propriety removed to a different genus.

      We procured also, during the first few days of our stay, a species of Felis, said to be common in the woods. It has much the appearance of a species of Viverra. The body is very long, though in other respects it is nearly of the size of a cat. It is remarkably fierce, and flies at every thing that approaches; body black, with gray stripes, tail very long, breast whitish.

      A handsome species of Sciurus. The head large and globular; body and tail dark gray; belly brown; top of the tail brown.

      A species of Vespertilio.

      The number of birds that we saw was inconsiderable. The principal are the Buceros, Pelican, (in Mr. Philips’s grounds several are domesticated,) several species of Alcedo, a solitary Adjutant, a fishing Vulture, five species of Certhia, and several other Passeres; of Corvus two species; Fulica; and Columba two species.

      To describe or to enumerate the numerous vegetable productions which are to be found in this island, is but little compatible with the plan of a journal such as this. For an account of what has been done in this way, I refer to the catalogues, descriptions, and drawings. Several circumstances have conspired to render these less extensive and less complete than was desirable. The mechanical labour and personal fatigue, incurred in collecting materials, were necessarily very great; that of preserving them afterwards considerable; and the aid to be derived from persons of the labouring classes was not always at my disposal. Neither was the present season the most favourable for botanical pursuits. The brumal distance of the sun is felt, even in the intertropical regions. In these islands more particularly, this distance is rendered sensible, by unusual vicissitudes in the atmosphere, not only in point of temperature, but as regards the state of the winds, their capacity for retaining or depositing moisture; the greater prevalence of electric phenomena; the remarkable variations in the appearance of the clouds. Rains at this time are prevalent. Towards evening the clouds accumulate in thick masses, the winds often blowing with tempestuous fury, and the face of day is darkened; the effect of these circumstances on the vegetable world is very sensible, and yet the thermometer at this period of the year rarely descends under 70° near to the equator. But even this indicates a degree of cold, which in these climates acts more sensibly on the human body than would be easily credited by an inhabitant of a cold region. The effect is, doubtless, the more powerful from the presence of universal moisture in the air, amounting very commonly to saturation. A degree of brumal influence is therefore extended to the vegetable world; the greater number of plants have ceased to flower; many trees cast a large proportion of their leaves, and have a degree of nakedness not common to them at other times. This influence is still more sensibly felt on vegetation at various elevations above the sea. On the hills it is most observable in arborescent botany. On the highest, very few plants, and those chiefly herbaceous, are now to be found in flower. In the plains, however, and in the sheltered acclivities of mountains, this circumstance is less observable. Besides, with a considerable number of the plants which grow in such places, the present is the proper and natural period of flowering; and the number is not inconsiderable of such as are to be found in flower, or in fruit, at all seasons of the year.

      The altitude of the mountain ridges in Penang is not so great as to produce a very marked difference in the geographic distribution of its vegetable productions. The highest point of land is that on which the flag-staff is placed; and this, by barometric measurement, gives an altitude of two thousand two hundred and twenty-three feet, above the governor’s house, which may be reckoned about twenty-five feet above the level of the sea; so that the greatest altitude will be two thousand two hundred and forty-eight feet. Within this space, however, the more experienced botanist, will detect a sensible difference in the distribution of the vegetable forms. In the low grounds which extend from the sea coast to the base of the hills, and for some distance up their flanks, he will recognise the favoured region of the Palms, and of the greater number of the Scitamineæ, vying with the former in utility, whilst they even excel them in the beauty of their general appearance.

      Of the intertropical plants, the most superficial observer will have remarked, that a considerable proportion are influenced scarcely less in their geographical distribution by longitudinal than by latitudinal position; and, if we divide the globe into hemispheres, we shall find that the plants of an eastern differ from those of a western hemisphere scarcely less than those of the northern from the southern. We may thus observe a constant tendency to confine plants to a particular spot, to isolate, and to increase their number; and that though, like man, some are capable of existing in a great variety of climates, yet that these are to be considered as exceptions to a great and general rule. Within the tropics this limited distribution of plants is more remarkable than in the other zones. It is especially observable in the distribution of Palms, Scitamineæ, and the more valuable spices and aromatics. Heat alone is not sufficient for their production, or we should find them more general throughout the torrid zone, while, in fact, they are respectively confined to very narrow limits. Within the tropics, from the equator to nearly 20° N., and on the level of the ocean, or but slightly elevated above it, we distinguish a belt, within which are contained almost all the Palms with which we are acquainted. They constitute the most remarkable vegetable production within this space. As to distribution, we notice various points at which, without apparent alteration of temperature, they are respectively limited.

      Of the Cocoa-nut we may remark, that it grows with the greatest luxuriance and perfection in the Maldive and Laccadine Islands, on the south and west coasts of Ceylon, on the coasts of Malabar and Coromandel, and west as far as Bombay. At Penang this Palm is evidently less productive, and therefore less extensively cultivated. It is replaced by the Areca catechu; by Nipa fruticans, Cycas circinalis, and a few others. The Sea Cocoa-nut, as it is called, is still more limited in its distribution; and the Borassus gomutus is almost equally so. Here, too, it is rare to see a single specimen of the Borassus flabelliformis, a palm so common in other parts of India. СКАЧАТЬ
