Vi PREFACE. 



with the general structure of the cat, and at the same 

 time introduce him to some of the most important mor- 

 phologic features of the Mammalia. The following works 

 are useful for reference: "Anatomical Technology," 

 Wilder and Gage; "Anatomy of the Cat," Reighard and 

 Jennings; "Mammals Living and Extinct," Flower and 

 Leydekker; "Primary Factors of Organic Evolution," 

 E. D. Cope; "Vertebrate Zoology," J. S. Kingsley; 

 "Anatomic des Hundes," Ellenberger and Baum; 

 "Human Physiology," Schenck and Giirber; 'Osteology 

 of the Mammalia," Flower; " Human Histology," Piersol. 

 In the preparation of this book I have consulted a 

 large number of works on human and comparative 

 anatomy and physiology. Those giving most assistance 

 are the works mentioned above, in addition to 'Mam- 

 malian Anatomy' by Jayne, 'Anatomic Descriptive et 

 Comparative' by Strauss-Durckheim, ' Nervose Central- 

 organe' by Edinger, and "Vertebrate Palaeontology' by 

 Woodward. I am especially indebted to my artist, Mr. 

 W. H. Reese, of the Phillipsburg High School, for the 

 care and patience exercised in making the drawings 

 from my own dissections. Mr. D. S. Hartline, of the 

 Bloomsburgh State Normal School, has read the entire 

 manuscript and made valuable criticisms. Above all, I 

 have to thank Prof. J. S. Kingsley for numerous valuable 

 suggestions and important corrections in the manuscript.
