Dr. Starr has devoted many years of his professional service to the special study 

 and treatment of children ; his book has been written out of a wide and long ex- 

 perience, and the methods recommended are those which, as a deeply interested 

 worker, the author has found most practical and efficacious. 



The work bears a message of great importance to parents, school officials, 

 teachers, psychologists and others who are interested in the proper development 

 of the child and who, in particular, should understand the physical and psychical 

 changes that occur, and should have in mind some clearly defined measures with 

 which to combat the dangers and insure the evolution of adolescence into healthy 

 and useful maturity. It points out the early signs of certain tendencies in children 

 and shows how to guide and train the child for the best results.

 those of the earlier editions.
