ood; and as the parotitis or mumps had not long before
prevailed amongst human beings in that part of the country, I recollect
being inclined to believe, that the cats received the infection from
mankind; though in all other contagious diseases, except the rabies canina
can be so called, no different genera of animals naturally communicate
infection to each other; and I am informed, that vain efforts have been
made to communicate the small-pox and measles to some quadrupeds by
inoculation. A disease of the head and neck destroyed almost all the cats
in Westphalia. Savage, Nosol. Class X. Art. 30. 8.

5. _Catarrhus sensitivus_ consists of an inflammation of the membrane,
which lines the nostrils and fauces. It is attended with sensitive fever
alone, and is cured by the steam of warm water externally, and by diluents
internally, with moderate venesection and gentle cathartics. This may be
termed catarrhus sensitivus, to distinguish it from the catarrhus
contagiosus, and is in common language called a violent cold in the head;
it differs from the catarrhus calidus, or warm catarrh, of Class I. 1. 2.
7. in the production of new vessels, or inflammation of the membrane, and
the consequent more purulent appearance of the discharge.

Raucedo catarrhalis, or catarrhal hoarseness, is a frequent symptom of this
disease, and is occasioned by the pain or soreness which attends the
thickened and inflamed membranes of the larynx; which prevents the muscles
of vocallity from sufficiently contracting the aperture of it. It ceases
with the inflammation, or may be relieved by the steam of warm water alone,
or of water and vinegar, or of water and ether. See Paralytic Hoarseness,
Class III. 2. 1. 4.

6. _Catarrhus contagiosus._ This malady attacks so many at the same time,
and spreads gradually over so great an extent of country, that there can be
no doubt but that it is disseminated by the atmosphere. In the year 1782
the sun was for many weeks obscured by a dry fog, and appeared red as
through a common mist. The material, which thus rendered the air muddy,
probably caused the epidemic catarrh, which prevailed in that year, and
which began far in the north, and extended itself over all Europe. See
Botanic Garden, Vol. II. note on Chunda, and Vol. I. Canto IV, line 294,
note; and was supposed to have been thrown out of a volcano, which much
displaced the country of Iceland.

In many instances there was reason to believe, that this disea
