EXPEBIMENTAL AND CHEMICAL STUDIES 



OF THE BLOOD WITH AN APPEAL FOB 



MOBE EXTENDED CHEMICAL TBAIN- 



ING FOB THE BIOLOGICAL AND 



MEDICAL INVESTIGATOB^ 



Before beginning my address let me say 

 that I feel it to be a very great honor to 

 have been asked to deliver the first Mellon 

 Lecture under the auspices of the Society 

 for Biological Research of this university. 

 The establishment of a lectureship of this 

 character is a great encouragement to men 

 of science. It affords additional opportu- 

 nity to bring to the attention of a wider 

 public the recent results of scientific inves- 

 tigation as well as to emphasize again a 

 truth which can not be too often repeated, 

 that science constitutes a sure and lasting 

 part of the intellectual treasure which man- 

 kind possesses. - 



I have ventured to take as the subject of 

 my address some recent experimental and 

 chemical studies of the blood. In order to 

 give my subject a proper setting I must, 

 first, refer briefly to the history of blood- 

 letting, and to make clear its relation to 

 pressing medical problems, I shall in the 

 hour discuss the interaction of the blood 

 and the organs of internal secretion. 



The overwhelming significance of the 

 blood to all people in all times is shown in 

 folic sayings, in tradition and in literature. 

 The expressions, "the life of flesh is in the 

 blood," "tainted blood," "blood will tell," 

 "blood oath," "blood brother," all suggest 

 how nearly blood has been held to be synon-
