The list of wanton omissions is not yet complete! C. S. Minot, the great American embryologist, is ignored. Theobald Smith, the pathologist, is also thought unworthy of note. And among those renowned American scientists who, though mentioned, failed to impress the Encyclopædia’s English editor sufficiently to be given biographies are: John Kerasley Mitchell, who was the first to describe certain neurological conditions, and was one of the advocates of the germ theory of disease before bacteriology; William Beaumont, the first to study digestion _in situ_; Jacques Loeb, whose works on heliotropism, morphology, psychology, etc., have placed him among the world’s foremost imaginative researchers; H. S. Jennings, another great American biologist; W. H. Welch, one of the greatest of modern pathologists and bacteriologists; and Simon Flexner, whose work is too well known to the world to need any description here. These men unquestionably deserve biographies in any encyclopædia which makes even a slight pretence of completeness, and to have omitted them from the _Britannica_ was an indefensible oversight—or worse. The editors of the _Encyclopædia Britannica_ cannot explain away these amazing omissions on the ground that the men mentioned are not of sufficient importance to have come within the range of their consideration; for, when we look down the list of _British_ medical scientists who are given biographies, we can find at least a score of far less important ones. For instance, Elizabeth G. Anderson, whose claim to glory lies in her advocacy of admitting women into the medical profession, is given considerably over half a column. Gilbert Blane, the introducer of lime-juice into the English navy, also has a biography. So has Richard Brocklesby, an eighteenth-century army physician; and Andrew Clark, a fashionable London practitioner; and T. B. Curling; and John Elliotson, the English mesmerist; and Joseph Fayrer, known chiefly for his studies in the poisonous snakes of India; and J. C. Forster; and James Clark, an army surgeon and physician in ordinary to Queen Victoria; and P. G. Hewett, another surgeon to Queen Victoria; and many others of no more prominence or importance. In order to realize the astounding lengths of injustice to which the _Britannica_ has gone in its petty neglect of America, compare these English names which are given detailed biographical consideration, with the American names which are left out. The editors of this encyclopædia must either plead guilty to the most flagrant kind of prejudicial discrimination against this country, or else confess to an abysmal ignorance of the history and achievements of modern science.
