Note k — BOOK VIII.

Of Insects bred in the Nose of Animals, those in the Nostrils of Sheep are remarkable. I have my self taken out not fewer at a Time than twenty or thirty rough Maggots, lying among the Laminæ of the Nostrils. But I could never hatch any of them, and so know not what Animal they proceed from: But I have no great doubt, they are of the Ichneumon-Fly Kind; and not improbably of that with a long Tail, call’d Triseta, whose three Bristles seem very commodious for conveying its Eggs into deep Places.

I have also seen a rough whitish Maggot, above two Inches within the Intestinum rectum of Horses, firmly adhering thereto, that the hard Dung did not rub off. I never could bring them to Perfection, but suspect the Side-Fly proceeds from it.
