74 Introduction of the Vaccine Disease 



the number of persons, who, at this time, had not 

 been vaccinated, as well as on account of the then 

 want of confidence in the protecting power of vacci- 

 nation. It was necessary, therefore, to make the ship 

 perform a quarantine at one of the Schychelles. 



I placed on board six children of X\io%&Jirst vacci- 

 nated. I directed the surgeon (whom I had placed on 

 board the vessel for this purpose) to keep these chil- 

 dreji constantl)' among those who were infected with 

 the small-pox ; to make them eat and drink out of 

 the same plates and cups ; to make them wear the 

 linen of the sick ; and, finally, to inoculate them fre- 

 quently with variolous matter. I likewise caused to 

 be taken on board, a child, that had been vaccinated, 

 and the matter of whose pustule was in the proper 

 state for communication, in order to vaccinate forty of 

 the negroes, who had not then taken sick. The result 

 of these trials was, that the six vaccinated children 

 were completely preserved, and that the success 

 w hich attended the vaccination of the blacks was sd 

 perfect, that the small-pox became extinct. There 

 \\?€re no more sick after the second day : many of 

 them took the vaccine, and had the pustule. It had 

 no effect upon others, these having, no doubt, already 

 bad the small-pox. 



I feel happy in believing, that the knowledge of this 

 fact (which is familiarly known to the whole Colony) 

 will appear to you of a nature to subdue the most re- 

 fractory unbelievers in the preserving power of the 

 vaccine disorder. I know not the prevailing opinion
