PREFACE Vll 



fied form. It consists primarily of the rules for measurements given in 

 the two prescriptions of 1906 and 1912, and adds for the convenience of 

 the student certain of the most useful indices. An enumeration of 

 instruments, as employed in various places, is given in the introduction, 

 together with a much simplified account of the most generally used 

 mathematical methods employed in tabulating and expressing the results 

 of measurements, for the especial benefit of that large class of students 

 who find their chief interest in the morphological relations of the subjects 

 treated, but whose mathematical ability is not great, and who are not 

 able readily to follow the more abstruse methods and expositions of them 

 made use of by biometricians. 



The student is introduced to the bibliography of the subject by a 

 series of footnotes, which are found under each heading, and are intended 

 to guide him to certain of the most important papers, generally the ones 

 especially followed in this book. From the bibliographies given here, in 

 their turn, a more complete knowledge of the literature may be obtained. 



The main work is followed by two appendices, the one (A) giving the 

 actual measurements of 93 skulls and skull fragments of Indians from 

 Southern New England, the other (B) the bodily proportions of 100 

 Smith College Students, both sets of measurements the result of work 

 carried out in the Smith College Anthropological Laboratory by gradu- 

 ate students. These may prove useful as samples of the kind of work 

 treated in this manual, and will be of interest to use in comparison with 

 the results of the practical reader.
