VACCINATION A PREVENTATIVE; OF THE PLAGUE. 



Hxtract of a Letter from J. de Carro, j\L D. of Fienna, 

 to Dr.^C. F. Haug, of Rasfadf. 



August, 23, 1803. 



VV HAT will excite your admiration, as well as that of the 

 whole world, is a new discovery made by two physicians, 

 iiamelv, Dr. Aubon, of Constantinople, and Dr. Lafond, 

 of Salonica, in Macedonia. Tlie experiments of these two 

 physicians, who never have had any intercourse, confirm 

 that the vaccine is a preservative against the plague. 'F"hc 

 proofs of the former are, that of 6,000 persons moculated 

 with the vaccine at Constantinople, not one of them was at- 

 tacked by the plague ; that children subjected to the vac- 

 cine inoculation were made to suck mothers attacked by 

 the plague without any of them being infected ; that an 

 Italian physician, who devoted himself in Turkey to the 

 study of the plague, being fully convinced of the property 

 which the vaccine has of preserving from this malady, took 

 every opportunity of coming into contact with persons in- 

 fected by the plague, in an hospital destined for patients 

 afflicted with that disease : that in consequence of accurate 

 researches the vaccine pustules have been found on the teats 

 of the cows, and the hands of those who milk them, in 

 the villages around Constantinople : that it results from the 

 account of persons worthy of credit, that in their country 

 neither the plague nor the small-pox have ever prevailed 

 epidemically, even when these scourges made the greatest 

 ravages in the neighbourhood : that when an inhabitant of 

 these villages has been infected with the plague in distant 

 countries, and returns with that malady, he has either died 

 or been cured without the disorder spreading : in the last 

 place, that the confidence of several classes of men, and 

 chiefly of the Armenians, in the preventive quality of the 

 vaccine against the^ plague, is so great, that a number of 

 people are inoculated eveiy year with it to preserve them 

 from this malady The physicians of Constantinople have 

 begged me to contribute towards the promulgation of this 

 new discovery, &c.
