other, when expanded) this pretty little grey Moth (for such was the creature I observ’d, thus wing’d) could very nimbly, and as it seem’d very easily move its _corpuscle_, through the Air, from place to place. Other Insects have their wings cas’d, or cover’d over, with certain hollow shells, shap’d almost like those hollow Trayes, in which Butchers carry meat, whose hollow sides being turn’d downwards, do not only secure their folded wings from injury of the earth, in which most of those creatures reside, but whilst they fly, serves as a help to sustain and bear them up. And these are observable in _Scarabees_ and a multitude of other terrestrial _crustaceous_ Insects; in which we may yet further observe a particular providence of Nature. Now in all these kinds of wings, we observe this particular, as a thing most worthy remark; that where ever a wing consists of discontinued parts, the Pores or _interstitia_ between those parts are very seldom, either much bigger, or much smaller, then these which we here find between the particles of these brushes, so that it should seem to intimate, that the parts of the Air are such, that they will not easily or readily, if at all, pass through these Pores, so that they seem to be strainers fine enough to hinder the particles of the Air (whether hinder’d by their bulk, or by their _agitation_, _circulation_, _rotation_ or _undulation_, I shall not here determine) from getting through them, and, by that means, serve the Animal as well, if not better, then if they were little films. I say, if not better, because I have observ’d that all those creatures, that have film’d wings, move them aboundantly quicker and more strongly, such as all kind of Flies and _Scarabees_ and Batts, then such as have their wings covered with feathers, as Butter-flies and Birds, or twiggs, as Moths, which have each of them a much slower motion of their wings; That little ruggedness perhaps of their wings helping them somewhat, by taking better hold of the parts of the Air, or not suffering them so easily to pass by, any other way then one. But what ever be the reason of it, ’tis most evident, that the smooth wing’d Insects, have the strongest Muscles or movent parts of their wings, and the other much weaker; and this very Insect, we are now describing, had a very small _thorax_ or middle part of his body, if compar’d to the length and number of his wings; which therefore, as he mov’d them very slowly, so must he move them very weakly. And this last propriety do we find somewhat observ’d also in bigger kind of Flying creatures, Birds; so that we see that the Wisdom and Providence of the All-wise Creator, is not less shewn in these small despicable creatures, Flies and Moths, which we have branded with a name of ignominy, calling them Vermine, then in those greater and more remarkable animate bodies, Birds.
