Jfyving failed to find in books a satisfactory theory of those con^itioizs 

 which produce lateral curvature, Mr. Barwell resolved to in-vcsti- 

 gate the subject for himself ab initio. The present work is the 

 result of long and patient study of Spines, normal and- abnormal - 

 He believes the views which he has been ted to form account for those 

 essential characteristics which have hitherto been left unexplained i 

 and the treatment which he advocates is certainly less irksome, and 

 will be found more efficacious than that which has hitherto been 

 pursued. Indeed, the mode in which the first edition hcis been 

 received by the profession, is a gratifying sign that Mr. BanoelVs 

 principles have made their value and their weight felt. Many 

 pages and a number of woodcuts have been added to tite Second 

 Edition.
