There has been constant cooperation throughout, but, it may be proper 

 to state, the senior author holds himself particularly responsible for the 

 Introduction, the Preservation of Soft Parts, the Bones of the Limbs, the 

 Muscles, the Heart, the Central Nervous System and the Cranial Nerves ;

 Skeleton excepting the limbs, the Viscera, the Peripheral Vascular and Ner- 

 vous Systems and the Organs of Sense. 



Notwithstanding our efforts for accuracy, there are doubtless errors of 

 observation and interpretation. Corrections or suggestions will be gladly 

 received.
