But this would not suit them at all: they could not bear to be thus limited to here and now. Their arguments and their instances extend over thirty or more years, and are drawn from all parts of the world, from the United Kingdom, the United States, France, Germany, Italy, from every country. Journals of Physiology, text-books, reports, medical journals, British and foreign, are ransacked to find evidence for the cause; there is a regular system, year in year out, a sort of secret service or detective force, a persistent hunting-up of all scraps and shreds of evidence. One society advertised, in a daily paper, that it wanted confidential communications, from medical students, as to the practices of the laboratory. Another, seeing the chance of a prosecution, says, "Special inquiries were made on the subject, and the society's solicitor went to Belfast to conduct these inquiries on the spot." All this espionage is sure now and again, in thirty years, to detect something which it can magnify into a scandal. And when a fault is found, even a little one, oh the joy in the ranks of the societies. And, at once, the fault, exaggerated, and highly coloured, is made a _locus classicus_, a commonplace of every drawing-room meeting. What is the date of it, what was the place of it? Was it long ago, was it far from here? Still, never let it drop; what one did then, they are all doing now, all of them of malice prepense; let us proclaim the blessed news from every platform; and please remember us in your Wills.
