4670.—Hence we may learn how small importance is to be attached to the cicatrix as an evidence of the perfection or imperfection of the vaccine process. Perfect security is compatible with a small and scarcely distinguishable cicatrix or without a large wafery cicatrix at all; at least none perceptible five years after the operation—

Marson made answer—

Dr. Gregory was an authority; but he was a very singular man indeed, and had never investigated the subject in the extensive way I have.

Marson was the victim of a notion, and that a poor one, to which whatever stood in opposition was sacrificed. Among his assertions and admissions, the following are characteristic and illustrative—

4151.—If all children were properly vaccinated, the mortality from Smallpox would be less than 1 per cent. There are difficulties: there is the opposition of mothers to having their children well vaccinated.

4125.—Persons who catch Smallpox after being vaccinated do not generally have it until 18 to 25 years afterwards.

4220.—Smallpox itself is a much greater protection from Smallpox than Vaccination.

4136.—Certainly Smallpox has no tendency to die out: it is precisely the same disease it was a thousand years ago, and will be a thousand years hence.

4148.—We have no control over Smallpox: there is no specific. We have no power whatever of controlling Smallpox, Scarlatina, Measles, and other febrile eruptive affections.

4694.—I look upon hospitals as necessary evils. They are not places I would recommend the sick to go to. Anybody who can afford to keep in his house should not go to an hospital.
