employed towards the end of the conquest of 

 disease. 



In the development of all of this experience 

 in the thousands of surgical operations which 

 are being performed every day, there is going 

 on a constant exchange of opinions and reports 

 of methods and results through the medium of 

 societies, congresses and publications, which 

 give every individual worker much of the ben- 

 efit of the experiences of others. There are 

 no secrets in the world of scientific medicine.
