Página 115 - Suppose an unvaccinated person to inhale the germ of variola on a Monday, if he be vaccinated as late as the following Wednesday the vaccination will be in time to prevent smallpox being developed ; if it be put off until Thursday, the smallpox will appear, but will be modified ; if the vaccination be delayed until Friday, it will be of no use, it will not have time to reach the stage of areola, the index of safety, before the illness of smallpox begins; this we have seen over and over again, and...
Página 195 - ... the smallpox was always present, filling the churchyards with corpses, tormenting with constant fears all whom it had not yet stricken, leaving on those whose lives it spared the hideous traces of its power, turning the babe into a changeling at which the mother shuddered, and making the eyes and cheeks of the betrothed maiden objects of horror to the lover.
Página 191 - Establishment for 1854 it is stated "that the vaccine lymph does not lose any of its prophylactic power by a continued transit through successive subjects." Such an unqualified belief is not, however, by any means universal, as shown in various parts of the evidence collected by Mr.
Página 207 - Duly and efficiently performed, it will protect the constitution from subsequent attacks of small-pox as much as that disease itself will. I never expected it would do more ; and it will not, I believe, do less.
Página 218 - ... whether or not we have at this time, in the matter of cow-pox, a power at our command, capable, if duly employed, of depriving the poison of small-pox of all fatal influence over an immense majority of mankind. And on this subject there has been quite sufficient information collected, since the date of the papers, which were held decisive of the question fifty years ago, to show that the same inference is still inevitable, and that he who disputes it is equally unreasonable as he who opposes,...
Página 171 - 1 expect that cases of this sort will flow in upon me in no inconsiderable numbers ; and for this plain reason — a great number, perhaps the majority, of those who inoculate are not sufficiently acquainted with the nature of the disease to enable them to discriminate with due accuracy between the perfect and imperfect pustule. This is a lesson not very difficult to learn, but unless it is learnt, to inoculate the Cow Pox is folly and presumption.
Página 315 - Have you any reason to believe or suspect that lymph from a true Jennerian vesicle has ever been a vehicle of syphilitic, scrofulous, or other constitutional infection to the vaccinated person ; or that unintentional inoculation with some other disease, instead of the proposed vaccination, has occurred in the hands of a duly educated medical practitioner?
Página 155 - ... be blown out when you come to use it. If the lymph do not exude freely, the tube may require to be drawn several times more or less obliquely across the surface of the vesicle or cluster of vesicles until a sufficient charge has entered; but generally if the exudation be copious, and a drop of some size has formed before you begin to take your supply, the orifice of the tube need not, indeed, ought not, to touch the surface, but is merely to be dipped into the clear fluid; and one may commonly...
Página 153 - Either, 1st, make the lymph gravitate towards the middle, by holding the tube vertically and giving it a few slight shocks by striking *the wrist on the arm or table ; then seal the end by which the lymph entered, by applying it to the surface of the flame of a candle, or any similar flame. It melts over and is sealed immediately. . Proceed with the other end in the same way, but first plunge it suddenly, say half an inch into the flame, and as quickly withdraw it till it touches the surface, and...
Página 293 - Although the susceptibility of the virus of the cow-pox is, for the most part, lost in those who have had the smallpox, yet in some constitutions it is only partially destroyed, and in others it does not appear to be in the least diminished. By far the greater number on whom trials were made resisted it entirely; yet I found some on whose arm the pustule from inoculation was formed completely, but without producing the common efflorescent blush around it, or any constitutional illness, while others...
