From this time forward for a number of years Jenner paid annual visits to London, remaining there a great part of the season, incessantly occupied in vaccinating, in giving information and instruction on the subject verbally to many medical men, in writing to a vast number of persons who corresponded with him from all parts of the world, for every one who heard of the discovery and wanted to know more about it applied to the discoverer, and in social intercourse with people of note, whom he never failed to impress by his eloquence and perspicuity. We cannot follow here the many incidents which marked these years, his intercourse with royal personages, the addresses of congratulation and gratitude which he received from all kinds of localities and bodies of people, the foundation of the Royal Jennerian Society, and the like. A few, however, must find a place. A Dr. Pearson, to whom we shall have to refer again, distinguished himself at first as an ardent vaccinator, but subsequently he seems to have imagined himself entitled to much of the distinction which belonged to Dr. Jenner, and in order to secure this, set about forming a public “vaccine board,” in which the chief official status was assigned to himself. He succeeded in obtaining the patronage of the Duke of York and other notable persons. Addressing Jenner on the subject, in December 1799, Pearson says: “It occurs to me that it might not be disagreeable to you to be an extra-corresponding physician.... No expense is to be attached to your situation except a guinea a year as a subscriber, and indeed I think you ought to be exempt from that, as you cannot send any patients.” This was pretty well, one might think, to be addressed to Jenner: in one year after the full publication of his discovery, he was to be shunted off as an “extra-corresponding physician.” Jenner’s answer showed the sense in which he regarded it. “It appears to me somewhat extraordinary that, an institution formed upon so large a scale, and that has for its object the inoculation of the cowpox, should have been set on foot and almost completely organized without my receiving the most distant intimation of it.... For the present I must beg leave to decline the _honour_ intended me.” After some discussion, most of the royal and influential personages who had promised to support Dr. Pearson’s institution withdrew their names from it. At Brunn in Moravia, where Count Francis de Salm introduced and widely diffused vaccination, the people erected a temple dedicated to Jenner, and annually held a festival on his birthday.
