“Did they?—yes—that old defamer of women, Horace Walpole, took good care to keep the public feeling from flowing in the right channel. He made people laugh at her dirty hands and painted cheeks, but he never urged them to heap honours on her head for introducing into England the practice of innoculation for the small-pox. If this American lady deserved the thanks and gratitude of her country for thus, for ever, preventing the loss of lives from steam, and I may say, too, from shipwreck—still farther was Lady Mary Wortley Montagu entitled to distinction, for the very great benefit she bestowed on England. She saved thousands of lives, and prevented, what sometimes amounted to hideous deformity, deeply scarred faces, from being universal.—Yes, the benefit was incalculable and beyond price—quite equal, I think, to that which the world owes to Dr. Jenner, who introduced a new form of small-pox, or rather the small-pox pure and unadulterated by any affinitive virus. This modified the disease to such a degree, that the small-pox, in its mixed and complicated state, almost disappeared. The Recorder of Self-Inflicted Miseries states, that after a time a new variety of the small-pox made its appearance, which was called _varioloid_; but it was quite under the control of medical skill.” “Well, you live in an age so much in advance of mine, and so many facts and curious phenomena came to light during the nineteenth century, that you can tell me what the settled opinion is now respecting small-pox, kine-pox, and varioloid.” “The settled opinion now is, that they are one and the same disease. Thus—the original disease, transferable from an ulcer of the cow’s udder to the broken skin of a human being, produced what is called the kine or cow-pox. This virus of the kine-pox, in its original state, was only capable of being communicated by contact, and only when the skin was broken or cut; but, when _combined_ with the other poison, infected the system by means of breathing in the same atmosphere. The poison from the ulcer called cow-pox was never communicated to or by the lungs, neither was the poison which had so strong an affinity for it communicated in that way: but when the two poisons united, and met in the same system, a third poison was generated, and the _small-pox was result_. But here we are discussing a deep subject in this busy place—what gave rise to it?—oh, steamboats, the new power now used, Lady Mary Wortley, and Dr. Jenner.” “I presume,” said the attentive Hastings, “that Dr. Jenner fared no better than your American lady and Lady Mary Wortley.” “You are much mistaken,” said Edgar. “Dr. Jenner was a _man_, which in your day was a very different circumstance. I verily believe if it had been a woman who brought that happy event about, although the whole world would have availed itself of the discovery, her name would scarcely be known at this day.”
