The Author tells us, that out of a great Drove, such as the Merchants bring yearly into _Italy_ out of _Dalmatia_ and the bordering Countries, one Beast happen'd to straggle from the rest, and be left behind; which a Cowherd brought to a Farm belonging to the Count _Borromeo_: This Beast infected all the Cows and Oxen of the Place where he was taken in, with the same Distemper he labour'd under; the Beast it self dying in a few Days, as did all the rest, except one only, who had a Rowel put into his Neck. 'Tis no strange thing therefore, if from the Effluvia, proceeding from the sick and dead Cattle, and from the Cow-Houses and Pastures where they were fed, and perhaps from the Cloaths of the Cowherds themselves, this Infection falling upon a proper Subject, should diffuse it self so largely. When therefore this subtile _venomous Exhalation_ happens to meet with any of the Cow-kind, joining it self with the serous Juices and Animal Spirits, 'tis no wonder it should disorder the natural Consistence of the Blood, and corrupt the Ferments of the Viscera; whence it follows, that the natural Functions of the Viscera are vitiated, and the requisite Secretions stopt. For Dr. _Ramazzini_ not only supposes, but asserts, that a Poison of this kind, rather fixes and coagulates, than dissolves the Blood: For beside the forementioned Symptoms accompanying the Disease, the Eye it self is a Witness; since the dead Carcases being open'd while they are yet hot, little or no Blood runs out; those Animals having naturally a thick Blood, especially when the fever has continued so many Days. And he adds, that whether this Plague came first from the Foreign Beast, or any other way, it only had its Effect upon some Animal, in which there was the morbid Seminary or Ground prepared for it. In the dead Bodies of all the Cattle, it was particularly observ'd, that in the Omasus, or Paunch, there was found a hard compact Body, firmly adhering to the Coats of the Ventricle, of a large Bulk, and an intolerable Smell: In other Parts, as in the Brain, Lungs, _&c._ were several Hydatides, and large Bladders fill'd only with Wind, which being open'd, gave a disagreeable Stink: there were also Ulcers at the Root of the Tongue; and Bladders fill'd with a Serum on the sides of it. This hard and compact Body, like Chalk, in the Omasus, the Author takes to be the full Product of the contagious Miasma. He adds a Prognostick, believing that from so many Attempts and Experiments, and the Method observ'd in the Cure of this Venom, at last a true and specifick Remedy will be found out to extirpate the poisonous Malignity wholly: He also expects some mitigation of it, from the approaching Winter and North Winds. He does not think this Contagion can affect Human Bodies, since even other Species of ruminating Animals, symbolizing with the Cow-kind, are yet untouch'd by it; nor was the Infection taken by the Air, after the dead Bodies had been carefully Buryed.
