Sentence:  <WSD>Hydrophobia</WSD> may, without risk, be applied to the disease in mankind, and serve to distinguish it; but it would be most injudicious to retain it as a designation for the madness or rabies of the lower animals. ... "<WSD>Hydrophobia</WSD>" is not even a proper designation for the malady in him [man], inasmuch as authors have described a spontaneous <WSD>hydrophobia</WSD> in the human species, or certain symptoms resembling those of <WSD>hydrophobia</WSD>, which certainly were not the same as those produced by the bite of a rabid animal, neither was the presence of a transmissible virus proved to exist. 
Meaning of the word marked with <WSD> tags:  An aversion to water, as a symptom of rabies;  the disease of rabies itself.
