Excerpt from The Systematic Relationships of the Coccace?: With a Discussion of the Principles of Bacterial Classification
This book is the outgrowth of an attempt to classify certain bacteria of sanitary importance belonging to the family of the Coccace?. The task was a difficult one on account of the marked variability of the organisms in question. As in other groups of bacteria, an almost infinite number of minutely differing varieties were apparent. Biometrical methods, which have yielded such fruitful results in anthropology, and in various researches in heredity, seemed to offer the most hopeful method of attacking the problem. The attempt was therefore made to discover natural types among the Coccace? by a study of the numerical frequency with which various characters occur. Those characters, or combinations of characters, which are exhibited by a large number of races, as they are found under natural conditions, may be taken to mark true centers of variation, about which the rarer varieties should properly be grouped.
