The like Plague is said to happen frequently in the Country of the _Cossacks_ or _Ukrani_, where, in dry Summers, they are infested with swarms of _Locusts_, driven thither by an _East_, or _South-East_ Wind, that they darken the Air in the fairest Weather, and devour all the Corn of that Country, laying their Eggs in Autumn, and then dying; but the Eggs, of which every one layeth two or three Hundred, hatching the next Spring, produce again such a number of _Locusts_, that then they do far more mischief than before, unless Rains fall which kill both Eggs and Insects, or unless a strong _North_ or _North-West_ Wind arise, which drives them into the _Euxine_ Sea: And it is very natural to suppose, that if the Winds have this Power over the larger sort of Insects; _i. e._ of moving them from one Country to another, the smaller kinds, which are lighter than the Air it self, may be interceptibly Convey'd as far as the Winds can reach. _Dr._ Wincler, _Chief Physician of the Prince_ Palatine, _gives us the following Account of the_ Murrain _in_ Switzerland, _and the Method of its Cure, in a Letter to Dr._ Slare, _F. R. S. Anno_ 1682. On the Borders of _Italy_ a _Murrain_ infested the Cattle which spread farther into _Switzerland_, the Territories of _Wirtemburg_, and over other Provinces, and made great destruction among them. The Contagion seem'd to propagate it self in the form of a _Blue Mist_, that fell upon those Pastures where the Cattle Grazed, insomuch that Herds have returned home Sick, being very dull, forbearing their Food, most of them would die away in twenty four Hours. Upon dissections were discovered large and corrupted Spleens, sphacelous and corroded Tongues, some had _Angina Maligna's_. Those Persons that carelesly managed their Cattle without a due respect to their own Health, were themselves Infected and Died away like their Beasts. Having had timely Notice of this _Lues_ from our Neighbours, we made such Provision against the invading Disease, that very few of those who were infected by the Murrain died. Some impute this Contagion to the Witchcraft of three _Capuchins_ in _Switzerland_. But the more learned believe it to proceed from some _noxious Exhalations_ thrown out of the Earth by three distinct Earthquakes perceived here and in our Neighbourhood in the Space of one Year. _The Method of Cure for the Cattle._ As soon as ever there was any suspicion of the Contagion upon any one of the Herd, the Tongue of that Beast was carefully examined, and in case they found any Aptha or Blisters whether White, Yellow, or Black, then they were obliged to rub, and scratch the Tongue with a Silver Instrument (being about the breadth and thickness of a Six-pence, but indented on the sides, and having a Hole in the middle whereby it is fastened to a Stick, or Handle,) 'till it Bleed, then they must wipe away the Blood with new unwashen Linnen. This done, a Lotion for the Tongue is used, made of _Salt_ and good _Vinegar_.
