This gives one case of small-pox in the vaccinated to 24 among the unprotected, and as I have shown that at the beginning of the epidemic the protected out-numbered the unvaccinated children, it is a striking testimony to the protective power of vaccination. That power, as well as the advantages of vaccination in modifying and controlling when it cannot altogether prevent the disease, is, however, much more clearly seen, and stands out in higher relief when the post* vaccinal series of cases is analysed, as in the accompanying cases, the their

SMALL-POX & VACCINATION IN BIIUETPOOE.?BY E. IIAEVEY.

Most of the children, continued to play about during the whole of the disease, and in none of them was there any secondary fever. Of the whole post-vaccinal cases only one was fatal. The child had one bad scar, but the pustules were distinct and few in number, and I fully expected that it would recover. I saw it on the 7th day, and going on the ninth to enquire whether it liad any secondary fever, learned that it liad died the preceding evening. This is, so far as I know, the only death which occurred during the epidemic in any child bearing marks of vaccination. The number of post-vaccinal cases is too few to draw absolute conclusions from, yet so far as they go, they show that while each vaccinated child had, as compared with the unvaccicourse

had 138 to 1 that lie did not die of it; the death-rate in the vaccinated being 3'22 per cent., and in the unprotected 18"55, 5'76 times greater. By facts like these, and I have spared no pains to ensure their accuracy, vaccination is " demonstrated" to be not ft inefficacious" but of the very highest value in India:?of a ?value I believe as high of the same kind and in the same degree as in the colder climates of the continent of Europe. The actual number of post-vaccinal cases is perhups larger than might have been cxpccted, considering the rarity of the affection in children, and the short time that had elapsed since the vaccinations had been performed?the time varied from one

to seven years, and the average age of the children was a over four;?but it must be remembered that the poison was everywhere prevalent and much concentrated, that the

little

produced by the vaccine operation had been very imperfect in many of the children, and that those with good cicatrices, though exposed to strong infection, had the disease so slightly as to run almost no risk of a fatal termination. The remaining seven cases on the list are cases vaccinated while incubating small-pox, too late to prevent its manifestation, yet early enough for the vaccinia to modify and control to some extent the action of tlio variolous poison. It may be well to mention, for the benefit of the unprofessional reader, that after exposure to smalL-pox infection twelve days elapse before the manifestation of the disease, while the protection conferred by vaccination is attained on the development of the areola in from eight to nine days after the vaccine operation. If, therefore, a person exposed to the contagion of small-pox be vaccinated within three days of his exposure, the vaccine disease, getting the start of the variola, prevents its development. If vaccinated on the fourth day he will contract small-pox, but the diseace will be modified by the vaccination, but if more than four days have elapsed the vaccination will be of none effcct, and the small-pox, having the start of the vaccinia, will run its natural courso as if no operation had been performed. In the Bhurtpoor epidemic 41 cases were noted of concurrent variola and vaccinia. It is, of course, im? posible to say how many more were vaccinated while incubatin
