in the Ground, out of which those Insects broke forth in the Form of
_Maggots_, which turn'd into _Flies_ that had a kind of Sting, which they
stuck into the Tree, and thereby envenom'd and killed it.

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
