unsusceptibility, so that very often two or more out of se- 

 veral children in such families tuck the small-pox after the 

 cow-]iock. According to the sevei^est tests, a very large 

 proportion were found nnsusceptible of small-pox after vac- 

 cination. Those who took the small-pox natnrally, in at 

 least 19 cases out of 20, had this disorder as mild as in the 

 mildest inoculated small-pox: hence another new patholo- 

 gical fact, and without analogy, that the human animal 

 ceconomy, although not rendered incapable of the small- 

 pox, may be rendered incapable of this disease severely, by 

 undergoing the vaccine. — Lastly; except ptrhaps some 

 slight eruptive comphiints, no new disease has been intro- 

 duced by the cow-pock. 



In this publication particular directions are given for the 

 mode of conducting vaccination. The rules also are spe- 

 cified to be observed by those who claim the compensation 

 of five guineas on account of having been afil'cted with the 

 small-pox after having been certified to be secure by means 

 of the cow-pock, by the medical officers of this Institution.
