The morphology, anatomy, neurology, psychology, earliest classifications were necessarily based anthropology and pedagogy, each course being upon the most superficial observations, and nuunder the supervision of a chief instructor. Ex- merous “ artificial systems” became current,

culminating in the famous one devised by Linnæus. These systems were “artificial,” in that they selected some one character as a basis, which would usually result in bringing an aggregation of plants together that held no real relationship to each other, just as the words in a dictionary are arranged in alphabetical sequence, resulting in bringing into juxtaposition words of most diverse origin. The dogma of the permanency of species lent itself kindly to these artificial arrangements; and if the determination of the name of a plant were the end of classification, artificial schemes would never fall into disuse, as they are far easier of manipulation than any natural scheme. Many of the earlier botanists were fully conscious of the fact that a natural scheme must ultimately replace the artificial ones, but
