THERAPEUTICS OF THE CIRCULATION. 



By Sir T. LAUDER BRUNTON, M.D., LL.D., F.R.S., 



Author of" Handbook of Pharmacology, Materia Medica, and Therapeutics." 



With numerous Diagrams. Medium %vo. 7s. 6d.ur/. [Just out. 



This book consists of eight lectures delivered in the spring of 1905 at the University 

 of London. They contain a short resume of the physiology of the circulation, of the action 

 of drugs upon it, and their uses in disease. It is by no means a complete text-book on the 

 subject, but while giving a general outline useful to students, it deals more especially with 

 subjects that are treated cursorily, if at all, in ordinary text-books, such as self-massage of the 

 heart and arteries, t lie curative action of cardiac tonics, the measurement of blood-pressure 

 in man, the treatment of excessive tension and its usefulness in prolonging life.
