The systematic relationships of the Coccacese with, a discussion of the 

 principles of bacterial classification, C. E. A. and Annp. R. Winsi.ow iXcir 

 Yorh- and London, 1908, pp. VIII+300, pi. 1, figs. 3; rev. in Science, n. ser., 29 

 (W09). So. 77/0. p. .387).— This book is stated to be the outgrowth of an attempt 

 to classify certain bacteria of sanitary importance, belonging to the family 

 Coccacete. An effort was made to discover natural types among the Coecacere 

 liy a study of the numerical frequence with which various charcaters occur. 

 From various sources r>00 different strains of Coccacete were isolated and sulv 

 uiitted to 11 d.'liuite and (iuautita*^ive tests. The results were analyzed with a 

 view to the centers about which each character varied in the series as a whole, 

 and to the general correlation between ditterent characters. 



The authors conclude that bacterial groups can be defined, and can only be 

 defined by a study of the numerical fre(pience of various characters in a large 

 series of cultures. In the Coccacese, " two main series, or subfamilies, may be 

 distinguished — one primarily parasitic and the other saprophytic. The groups 

 differ in morphology, staining reactions, cultural characters, and biochemical 

 powers. Within these 2 subfamilies are S minor groups which seem to merit 

 generic raidc. Each is n'.arked Ity the correlation of several apparently inde- 

 liendent characters, and the eight form, in general, a more or less linear series. 

 <-onnecting such purely parasitic forms as the meningococcus with the sapro- 

 Iiliytic cocci, so conunon in the air. Witliiii each genus are included o or 4 

 distinct sjiecific types, each marked by a single peculiarity but sharing the 

 conunon characters of the genus as a whole. Species and genera alike are con- 

 nected i»y numerous intergrading varieties; but the central types in each case 

 are defined i>y the preponderating frecpiency of their occurrence." 



A key to the genera and sjiecies of the Coccace;p and a bililiography are 

 appended.
