Excerpt from The Systematic Relationships of the Coccace�: With a Discussion of the Principles of Bacterial Classification

Extensions of this work by the examination of other cultures of cocci, by more extended tests, are much to be desired. Such investigations will no doubt add new genera and species and may show that some of those now apparently warranted are not really valid. It seems to us, however, that the results here presented offer a working basis for classifying the Coccaceae which corresponds in the main With their natural relationships. The results so far attained have convinced us that the study of the numerical frequency of individual characters and of their mutual correlations offers a sound basis for bacterial classification; and we trust that other workers may be persuaded to adopt similar biometrical methods in studying the relationships of simple and variable forms of life.

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.
