RASTADT, September 5.

Doctor Haug, of this city, has received the following interesting letter from Dr. Carro, of Vienna dated the 23d of August.

"A discovery which will excite your astonishment, as well as that of the whole world, has been made by two physicians, a Mr. Aubon of Constantinople, and a Mr. Lafond of Salonichi, a city in Macedonia.

Spain has transferred the country of Louisiana to France, and France has transferred it to us. But we would previously address the people of such state, as of Constantinople, and a Mr. Lafond of Salonichi, a city in Macedonia.

The experiments made by these two medical men have a perfect, though merely accidental, coincidence: and those made by both give the assurance, that the vaccine matter is a sovereign prevention for the ravages, of the plague. The proofs of Mr. Aubon are, that of 600 persons inoculated by him with the vaccine matter in Constantinople, not one has been attacked by the plague;- that children who had been thus inoculated, were expressly put to the breast of their mothers while struggling with the plague, and nevertheless escaped all infection. That an Italian physician, at present in Turkey, solely for the purpose of gathering observations on the plague, from a conviction that the vaccine matter prevented infection, went fearlessly into the hospitals, and conversed with, and touched persons dangerously ill of the disorder, without the smallest consequence. That in the villages bordering on Constantinople, where the Cow-Pox is prevalent, the plague had made no progress-That when any inhabitants of those villages caught the infection in another place, and returned home, he either died or recovered, without infecting any other person. And, that lastly, the confidence of the Armenians in this preventative was so unbounded, that numbers annually underwent the vaccine mode of inoculation, expressly to guard against the plague."
