PREFACE. vii 



Certain of the facts noticed in these Lessons are recent 

 additions to science, yet in hardly any instance has reference 

 been made to their discoverers. Such references have been 

 omitted in order not to overload a school book with notes. 

 Indeed, I make very little claim to originality except as 

 regards the special mode adopted in my treatment of the 

 subject. By this I mean the exposition part passu of the 

 facts of human anatomy with a selection of those most 

 interesting and important in the anatomy of animals formed 

 on the same type as man himself. 



The originals of many of the woodcuts are from the works 

 of Professors Owen, Huxley, and Flower, and of Mr. Parker 

 and others. 



Some original drawings have been made from specimens 

 preserved in the Museum of the Royal College of Surgeons 

 and of the British Museum. Some have been added from 

 specimens in my own collection. 



I am happy here to express my obligations for the ready 

 kindness with which my requirements for illustration have 

 been supplied. 



I also feel It no less a duty than a pleasure to declare how 

 much I am indebted to a near relative, Mr. Henry Davies 

 Chapman, for having kindly undertaken, amidst the pressure 

 of other avocations, a patient revisal of the proofs of the 

 present work, the publication of which, but for this timely 

 assistance, might have been indefinitely delayed.
