ther, that thefe fpreading Epidemick Diftempers take 
their Progrefs from Eaft to VVefr. But this fhould be fur- 
ther confirmed by more frequent Obfervations before 
one may fafely determine any thing in this matter; how-

certain ; and 'tis not !efs certain that the Plague and Pe- 
ftilential Fevers rage more frequently in the Eaft towards 
Conjiantimple and the Levant firm in thefe more VYeftern 
Parts of Europe^ as if that feemed a more Natural Clime 
for their rife and propagation ; wdience the feveral E- 
ftates of Italy fo ufually impcfe on Ships coming from 
all Parts of Turkey into their Ports the ftrid obferving a 
Quarantine^ before they Land either their Paflengers, or 
their Goods. 
And this might lead us to Difcourfe fomethiog con- 
cerning the caule of thefe fort of fpreading Diftempers: 
But till we have a better ftock of more accurate Hifto- 
ries of them, and be further acquainted with their Na»

sign of thofe that candidly profecute Philofbphicai Ei> 
quiries to determine any thing as yet in this Point.
