Mr. Pellt. I would like to pursue this further but I believe we have 

 one more witness. I simply want to add my word of thanks. I think 

 everything you have said is very pertinent to the matter which this 

 committee now has under consideration and you have made a very 

 great contribution. 



Dr. Halstead. Thank you, sir. 



Mr. Rogers. Thank you so much. Dr. Halstead. 



We are pleased to have before the committee, Dr. George Sullivan, 

 who was a distinguished member of the President's Commission and

 upon now. Let Dr. Sullivan's biography appear at this point in the 

 record.

Dr. Sullivan. Thank you, Mr. Chairman. 



Mr. Chairman, my remarks will be very brief so that I won't hold 

 the subcommittee except that I want to add to what Dr. Halstead was 

 covering a little discussion of what I call marine medicine or bio- 

 medicine and even more aptly defined as diving medicine. 



AVhat I am talking about is really basic knowledge and is the under- 

 standing of the movement and transport of gases into and out of the 

 lungs, across the membrane of the lungs, and into and out of the body 

 tissues. 



Most here have heard of the term bends and relate this to the small 

 bubbles that form in the tissue and become painful as the diver returns 

 to the surface. 



However, few of us relate this process to the terms of the absorption 

 of oxygen or nitrogen or carbon dioxide or helium, or yes, even smog 

 through the lungs, not only absorbed through the lungs but into the 

 bloodstream and then into the muscles and brain. 



A study of diving medicine, of course, is the study of the transport 

 of these gases into the body.
