Eminent Living Geologists — Dr. C. D. Walcott. 5 



extended series under Cambrian Geology and Paleontology in 

 Smithsonian Miscellaneous Collections, including " Appendages of 

 Trilobites " (now in press). . 



Dr. Walcott' s activity in other directions besides his own scientific 

 field is well known. He is a director and was one of the founders 

 of the Besearch Corporation of New York City, which is affiliated 

 with the Smithsonian Institution. He is a member of two military 

 committees: chairman of the Executive Committee of the National 

 Advisory Committee for Aeronautics, appointed by President Wilson 

 in 1915, and chairman of the Military Section of the National 

 Kesearch Council. Since 1917 he has been President of the 

 National Academy of Sciences. 



Of his varied inquiries Dr. Walcott says, 1 " I have had generous 

 assistance in obtaining collections and exchanging publications with 

 students all over the world, including geologists, paleontologists, 

 zoologists, and paleobotanists in America and Europe, and in far- 

 away outposts of China, Siberia, India, Australia, and New 

 Zealand." 



In 1888 he visited Wales for the purpose of making a personal 

 study of the type district of the Cambrian system — the district 

 rendered classic by the original labours of Sedgwick and the 

 subsequent researches of Hicks. It was on this visit to England 

 that he presented his Cambrian researches before the International 

 Geological Congress at London. The London Geological Society in 

 1895 awarded him the Bigsby Medal, and in 1918 the Wollaston 

 Medal. 



Dr. Walcott is an active member of many scientific and literary 

 bodies, both at home and abroad. These include the National 

 Academy of Sciences (President), American Association for the 

 Advancement of Science (Fellow; Yice-President, 1893), American
