Note on Bats by Daylight. The circumstance of the bat's being seen on the wing in the middle of the day, is of no uncommon occurrence, and has been noted in the pages of The Zoologist;' but in these instances no other than the common little pipistrelle is referred to, with the simple circumstance that the animal was busily employed in hawking for flies. I have repeatedly witnessed the same thing, and even in weather sufficiently cold to warrant the belief that the hunger of the bat must have been severe, to have caused it to take flight. But in the course of the past summer, two instances have come under my notice, which were attended with sufficient novelty to deserve a separate record. May 24, at half-past 3 o'clock in the afternoon, whilst walking in a little plantation of trees, the sky somewhat cloudy, a bat approached and hovered so near to me, as to show that it was much at its ease, and intent on the pursuit of prey. I observed it take a fly from off a leaf without alighting, and it flew so gently and repeatedly near me as to afford me an opportunity of easily discerning that it was the long-eared species. So little of timidity did it display, that I made two or three attempts to strike it down with a branch of a tree covered with leaves, before it took the alarm and changed its situation. Its flight was visibly different from that of the pipistrelle, being more heavy, less agile, and with more of the owl-like flap of the wings. The other instance occurred on the 30th of August, at half-past 5 o'clock, with the sky clear, and the sun shining bright. It was the pipistrelle, and presently after its appearance it mounted high in the air—judging from the neighbouring hills, probably not less than 250 feet; and while making busy circles in pursuit of food, it had the ill luck to be perceived by a swallow, which immediately began a pursuit. It persecuted the poor animal by repeatedly striking at it, and following it closely in all its rapid turns, until at last it compelled the bat to descend to the shelter of the houses. But when the persecutor had withdrawn, the bat boldly mounted again to the region that seemed to teem with its favourite food. It was, however, again beset, and two or three swallows joined in the persecution, which, after no small time, and various attempts to keep aloft, at last compelled the bat to seek security by descending to shelter. Satisfied with their success, the swallows speedily rejoined their companions in the higher regions, where was a multitude of them engaged in their ordinary avocations; upon which they seemed to have regarded the bat as an unauthorized intruder. But a few minutes only had elapsed, when I was surprized to see the persevering little animal again mount aloft, and engage with much activity in the pursuit of what he seems to have thought he had as good a right to as his more powerful tyrants. But the last attempt was more unfortunate than the former; for incited perhaps by what they probably would have denominated the impudence of the proceeding, a host of
