ful Study and record of Embryological conditions, and no more inviting 

 and interesting field. Tiie mere collection, preservation, and compari-

 true knowledge of what should really constitute a species, and the 

 wonderful revolutions resulting from the study of the early history of 

 many species, will amply reward and interest the student.
