When the veracity of any person has been impugned, it is a duty which we owe to society, if it lies in our power, to endeavor to establish it; and when that person is a lady gallantry redoubles the obligation. Our chivalry is, on the present occasion, excited in favor of Madame Merian, who, toward the latter end of the seventeenth century, and during a two years' residence in Surinam, employed her leisure in studying the many interesting forms of winged and vegetable life indigenous to that prolific country. After her return to Holland, her native land, she published the results of her researches. Her writings, although abounding in many inaccuracies and seeming fables, contained much curious and new information; all the more valuable from the objects of her study having been, at that period, either entirely unknown to the naturalists of Europe, or vaguely reported by stray seafaring visitants; who, with the usual license of travelers, were more anxious to strike their hearers with astonishment than to extend their knowledge. These works were rendered still more attractive by numerous plates--the result of Madame Merian's artistic skill--with which they were profusely embellished. It is one of these which, with the description accompanying it, has caused her truth to be called into question by subsequent writers; who, we must conclude, had either not the good fortune or the good eyesight to verify her statements by their own experience. The illustration to which I allude represents a large spider carrying off in its jaws a humming-bird, whose nest appears close at hand, and who had apparently been seized while sitting on its eggs. Linnæus, however, did not doubt the lady, and called the spider (which belongs to the genus _Mygale_), "avicularia" (bird-eating). Whether this ferocious-looking hunter does occasionally capture small birds; or whether he subsists entirely on the wasps, bees, ants, and beetles which every where abound, what I chanced myself to see in the forest will help to determine.
