Dr. Castle's paper treats of an ancestral or atavistic coat-character of the guinea-pig present in most wild rodents but frequently absent in their tame varieties and which may be obtained by crossing certain domesticated varieties of guinea-pig. A full account is given of how the reversion in question may be secured, how its reappearance can be accounted for, and in what way the recovered character may be "fixed" or reestablished as a racial character together with the complete data which form the basis of this account. Dr. Little analyzes the observed phenomena of color inheritance in mice on the basis of Mendelian heredity and shows the relations of the various factors involved in the production of colors, to each other and to the coat and eye colors produced. The paper includes the analysis and description of the color factors and gives the experimental data on which the conclusions are based. -Classified First of Publications of the Carnegie Institution of Washington [1918]

Rickettsiae comprise a group of paleomorphic, coccobacillary microorganisms that are now regarded as true bacteria. Nicholas Rahon presents a collection of papers that deal exclusively with pathogenic rickettsiae. The selected papers--twenty-nine in all and fully illustrated--range from the sixteenth century to the modern era. A number of the papers are classics in the field and several of the selections appear in English translation for the first time. The editor provides a preface to each selection and his general introduction defines the subject matter, surveys historical developments in the field, and summarizes recent research.
