manner. The same treatment of the circulatory system of 

 various vertebrates is given a large place in the book. 



These few structures are mentioned to serve as examples of

 thorough and exhaustive method used throughout the whole 

 volume. What is true of the structures cited is equally true 

 for the various structures treated.

 book is written, we feel like giving it our hearty indorsement, 

 and in spite of any minor defects the work commends itself 

 strongly to us.
