750 EMBRYONIC DEVELOPMENT. 



professed Physiologist, no good purpose seems likely to be served 

 by here giving such an imperfect outline of the process as could 

 alone be introduced into a work like the present ; and the reader 

 who may desire information upon it will find no difficulty in obtain- 

 ing this through Systematic Treatises on Physiology.* 



* The admirable treatise of Prof. Kolliker " Entwickelungsgeschichte 

 des Menschen und des hoheren Thiere," is the most complete and satis- 

 factory exposition yet given of the Developmental process in the higher 

 Vertebrata. An excellent outline of the subject is given in Dr. Dalton's 

 " Treatise on Human Physiology," Third Edit., Philadelphia, 1864. And 

 the Author, in his "Manual of Physiology," Fourth Edit., 1865, has aimed 

 to include what is most important for the Student to know.
