To young scientists, the Service offers the 

 opportunity of working with men who 

 have achieved national or international 

 reputations. To all, it extends a wide vari- 

 ety of advanced training in basic or special 

 skills. About one out of five of the profes- 



sionals undertake some additional formal 

 training each year, many of them working 

 toward advanced degrees. Those who 

 strive for degrees often find that the re- 

 search they do on their jobs is acceptable 

 to their university as a dissertation topic.
