Nor is it only the beating upon this little membrane, by the inward and con-natural spirit as _Aristotle_ determines, or the outward air as _Scaliger_ conceiveth, which affordeth this humming noise, but most of the other parts may also concur hereto; as will be manifest, if while they hum we lay our finger on the back or other parts; for thereupon will be felt a serrous or jarring motion like that which happeneth while we blow on the teeth of a comb through paper; and so if the head or other parts of the trunk be touched with oyl, the sound will be much impaired, if not destroyed: for those being also dry and membranous parts, by attrition of the spirit do help to advance the noise: And therefore also the sound is strongest in dry weather, and very weak in rainy season, and toward winter; for then the air is moist, and the inward spirit growing weak, makes a languid and dumb allision upon the parts.
11. There is found in the Summer a kind of Spider called a Tainct, of a red colour, and so little of body that ten of the largest will hardly outway a grain; this by Country people is accounted a deadly poison unto Cows and Horses; who, if they suddenly die, and swell thereon, ascribe their death hereto, and will commonly say, they have licked a Tainct. Now to satisfie the doubts of men we have called this tradition unto experiment; we have given hereof unto Dogs, Chickens, Calves and Horses, and not in the singular number; yet never could find the least disturbance ensue. There must be therefore other causes enquired of the sudden death and swelling of cattle; and perhaps this insect is mistaken, and unjustly accused for some other. For some there are which from elder times have been observed pernicious unto cattle, as the Buprestis or Burstcow, the Pityocampe or Eruca Pinuum, by _Dioscorides, Galen_ and _Ãtius_, the Staphilinus described by _Aristotle_ and others, or those red Phalangious Spiders like Cantharides mentioned by _Muffetas_. Now although the animal may be mistaken and the opinion also false, yet in the ground and reason which makes men most to doubt the verity hereof, there may be truth enough, that is, the inconsiderable quantity of this insect. For that a poison cannot destroy in so small a bulk, we have no reason to affirm. For if, as _Leo Africanus_ reporteth, the tenth part of a grain of the poison of _Nubia_[SN: granum Nubiæ.], will dispatch a man in two hours; if the bite of a Viper and sting of a Scorpion, is not conceived to impart so much; if the bite of an Asp will kill within an hour, yet the impression scarce visible, and the poison communicated not ponderable; we cannot as impossible reject this way of destruction; or deny the power of death in so narrow a circumscription.
