天下之大,无奇不有。在塞外,有一种奇特的大麻蝇,其飞行速疾且无声,善喷“蛆”入目而伤人。它只要从人们眼前掠过,无须触及人体,便可凌空喷射“蝇卵”入人眼中。其“卵”入眼,即化为大量的约1毫米长、如头发粗细的小白虫,俗谓之“蛆”。该“蛆”活跃地遍爬于人的眼球表面,刺激眼睛,引起剧痛。当地人遇此,辊用莫合烟或纳斯白少许,用手帕包之, as big as World, nothing is nonexistent. Outside the plug, there is a peculiar flesh fly, which is fast and silent, and sprays it well to hurt people. As long as it passes people’s eyes and does not need to touch the human body, it can jet the “fly eggs” into the eyes of people. Its “egg” enters the eye, and it is turned into a large number of small white bugs about 1 millimeter in length, such as the thickness of the hair. The “cockroach” actively crawls over the surface of a person’s eyeballs, irritates the eyes and causes severe pain. The locals encountered this, the roller used a mo smoke or a little white, and wrapped it with a handkerchief.
