Thus _Schenkius_ (79), _Salmuth_ (80) and others have observ’d a _Dread
of Water_, without any Suspicion of a Bite, from _Malignant Fevers_.
Now in _These_ there is doubtless a Hot, Putrid _Ferment_ in the Blood;
and it is no wonder if Part of it be discharged upon the Throat and
Stomach, which we do evidently find in these Distempers to be more
particularly affected by It, especially towards the latter End, from
the _Aphthæ_, _Singultus_, and the like usual Symptoms of a fatal
Malignity.
Nay, _Hippocrates_ (81) himself seems more than once to have remarked
something like this Symptom in Fevers, and to call those who were thus
affected Βραχυπόται, or little Drinkers; for I cannot assent to Dr.
_Lister_, (tho’ _Cælius Aurelianus_ be on his side) who thinks that the
Βραχυπόται are ὑδροφόβοι, from the Bite of a Mad Dog; as well for other
Reasons, as because _Plutarch_ (82) assures Us, that the _Hydrophobia_
and _Elephantiasis_ were both first taken Notice of in the time of
_Asclepiades_ the Physician; who liv’d in the Days of _Pompey_ the
Great, many Years later than either _Hippocrates_ or _Aristotle_.
Neither is it amiss to add, that _Ioannes Faber_ (83) in the Dissection
of one who dy’d at _Rome_ of the Bite of a Mad Dog, and a _Hydrophobia_
succeeding it, found the Blood _Coagulated_ in the right Ventricle of
the Heart, the Lungs wonderfully _Red_ and _Tumefied_; but especially
the _Throat_, _Stomach_, and _Bowels_, bearing the Marks of the
Inflammatory Venom.
The same Observation has been made by others in Bodies Dead of this
Disease. Thus the _Acta Medica Hafniensia_ (84) relate one Case, in
which, part of the Liver was _Inflamed_, the Lungs Parched and Dry,
and the inner Coat of the _Stomach_ so _Mortified_, that it might be
abraded with one’s Fingers.
_Bonetus_ (85) tells _another_, where all the _Viscera_ were found quite
_arid_, without any Juice at all.
And in a very particular History of an _Hydrophobia_, lately published
at _Ulm_, (86) We are informed, that the _Stomach_, when opened,
discover’d the Marks of an _Erosion_ or Excoriation, with something
like a Gangrene, and Suffusion of Blood here and there. Which does very
well agree with the Observations in the _German Ephemerides_ (87), where
we find several _Footsteps_ of a _Sphacelus_ or Mortification in the
Bodies of Those who died _Hydrophobi_.
The Cure of this Poison is either immediately upon the Wound made, or
some Days after, before the Fear of Water is discover’d; for at that
time all Authors do agree the Malady to be Incurable; and the Reason is
plain from what has been already deliver’d.
