Wind is bred in the Ear also, of flegm contained therein; whence it comes to pass that thick Hea∣ring is alwaies accompanied with a noise in the head. For by the humor there is a stoppage, from whence comes deafness, and from the wind that proceeds from that humor, comes the none.
There are other causes of this noise, as a great stroak upon the head, a great sound, Ulcers in the Ears, a hot distemper, weakness, and exquisite sence.
A stroak, by moving the Spirits in the Head too violently, causeth a noise.
A great sound doth violently move the natural Air.
And Ulcers by the heat of the matter boyling and working, make a noise; and by the Spirits ga∣thered thither, and moving the Natural Air.
A hot distemper fills the inward Arteries of the Ear with much Spirit, whence a great beating noise proceedeth. Somtimes too much Spirit is sent by those Arteries into the Ears, and the Natural Air is thereby moved, from whence cometh a noise. And from this cause may come a continual none for some months or yeers.
Weakness of hearing useth to make a noise in the Ears, as in sick people, because every sence de∣bilitated is hurt by every violent or moderate object: so they who have weak sight, are offended by a small light.
And lastly, When the sence is most exquisite, as Galen, lib. 3. de comp. med. sec. lo••. cap. 1. there will be a noise in the Ears, becau••e even moderate objects are too vehement for it. Now this exqui∣site sence must be preternatural, for the exquisitness of ••ence cannot of its self produce a depraved acti∣on, but rather the more exquisire it is the le••s will it Err. This preternatural exquisitness of sence, comes from a hot distemper, ulcer, or the like: as parts inflamed do deprav••dly, that is painfully, feel moderate touchings. Or if the exquisitness of sence be Natural, you must suppose that the cau••e of the noise is Preternatural; for the vapor which is so little that it cannot be felt of dull sence, and so the action not be hurt, will be felt of him that hath exqui••••te ••ense, and will cause a noise; so that in one it is Preternatural, in another Natural.
There are divers sorts of sounds in the Ears, which proceed either from the quantity of the vapors as they are more or few, thinner or thicker, swift or slow in motion; for if the vapor be much, thick, and of quick motion, it wil make a noise like swift running water, or like a drum, or like ••ome such Musical Instrument, or a rushing wind, or the like; but if it be little, thick, and move quick, the noise is like the falling of a ••ree or House.
If it be much, thin, and swift in motion, it causeth a hissing, or is like falling of a gentle Water. If it be little, thin, and quick in motion, it causeth a tickling. If it be much, thick, and of slow motion, it makes a murmuring noise. If the matter be little, thick, and slow in motion, it makes a kind of whis∣pering noise. If it be much, thin, and of slow motion, it causeth a hissing. And lastly, Because the degrees of thickness and thinness, of greatness and smalness, of swiftness and slowness, are infinite, therefore there are innumerable sorts of sounds in the Ears.
There is no certain knowledg of the causes aforesaid, as Galen teacheth 3. de comp. med. sec. loc. c. 1. but we may make conjecture from the precedent Causes and Circumstances.
We conjecture that the noise comes from wind, because somtimes it ceaseth, and returneth again; as also when the Patient hath formerly used to eat windy meat.
It cometh by consent from other parts, when there is some peculiar disease in them.
It appears to come from the Brain when pain and heaviness of the Head went before, and when o∣ther sences also are hurt.
That the fault is in the Ears, appears by a continual noise without any intermission.
We know that that Disease comes from a cold matter; if the Patient be better for the use of hot things, and if in time of health great noise be not much disturbance.
The difference of sounds above mentioned, do shew whether the disease comes of thick or thin, many or few vapors, it will easily appear by what hath been said.
When it comes from the weakness of the faculty of hearing; as from some Diseases aforegoing, of which the Pati••nt is scarce recovered.
We conjecture that it comes from a hot distemper, and from an exquisite sence coming thereupon, when the Patient perceiveth a heat in his head about his Ears; when some hot Causes went before, and Medicines that discuss wind do encrease the disease: as also when the Patient in time of his health could not endure any great noise by reason of the exquisitness of sence.
As to the Prognostick: A new begun noise in the head is easily cured, but an old, hardly, and the more if it come from the French Pox. That which proceeds of a hot cause, is more easily cured than that which comes of a cold.
An old noise coming of flegm contained in the Ear, turneth to deafness; for when the matter is en∣creased, the passage of Hearing is stopped.
The Cure of this Disease is divers in respect of the diversity of Causes.
