 tended in the first place for teachers and for earnest students 

 of both sexes, not already acquainted with human anatomy. 



I have endeavoured, secondly, by certain additions and by 

 the mode of treatment, to fit them for students in medicine 

 and generally for those acquainted with human anatomy, but 

 desirous of learning its more significant relations to the 

 structures of other animals. 



My hope is that this little volume may thus serve as a 

 handbook of Human Morphology. 



Man has been selected as the type, because his structure 

 has been the most studied and is the most intimately known, 

 as also because our own frame is naturally the most interest-

 variations which nature shows in that type of structure to 

 which man's body belongs. 



So far as I am aware, this endeavour is the first of its
