PHYSIOLOGY, ANATOMY, ETC. 39 



Having failed to find in books a satisfactory theory of those conditions 

 which produce la tent I air-rat lire, Mr. Barivell resolved to im esti- 

 mate 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 led to form account for those 

 essential characteristics which have hitherto been left unexplained : 

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

 ?vill be found more efficacious than that which has hitherto been 

 pursued. Indeed, the mode in -which the first edition has been 

 received by the profession is a gratifying sign that Mr. B'arwelVs 

 principles have made their value and their weight felt. Many 

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

 Edition.
