the date of human occupation some five or six centuries in the 

 Hadhramaut. 



Dr. Jamme copied more than 1,000 graffiti in the main wadi and in 

 tributary wadies. Before liis work, no more than 60 or TO graffiti 

 were known in this entire area and these were on only two rocks. The 

 information thus gained will add enormously to our knowledge of 

 the history of Hadhramaut in pre-Islamic times. 



The material collected by Dr. Setzer is the first of its kind from 

 Arabia in the National Musemn collections. From an archeological 

 point of view, this collection of mammals will be extremely useful for 

 identifying bones recovered in excavations in this region. 



Dr. Van Beek and other members of his party were delighted by 

 the warm reception and excellent relations they enjoyed in Aden and 

 Wadi Hadhramaut. The American Consulate, the British Director of 

 Antiquities for the Colony, the Eoyal Air Force, the Protectorate 

 Secretary, the Residency Staif in Mukalla and Seiyun, and the officials 

 of the Katliiri State in Seiyun and the Qu'aiti State in Hadhramaut 

 were all extremely cooperative. 



En route to and from Aden, Dr. Van Beek visited several institu- 

 tions and met archeological colleagues in England, Italy, Sudan, 

 Ethiopia, and Jordan. Discussions were very profitable along the 

 lines of mutual research and also in connection with the exhibits pro- 

 gram of the Smithsonian, where a new hall of Old World archeology 

 is in the planning stage. 



For 2 months of the summer of 1961, Dr. Marshall T. Newman, 

 associate curator of physical anthropology, continued his now nearly 

 completed nutritional study of more than 100 schoolboys of Vicos, 

 Peru. He was accompanied by Dr. William J. Tobin, collaborator of 

 the Smithsonian Institution, and Mrs. Tobin. For several years Dr. 

 Newman and Dr. Tobin have been collaborating with staff members 

 of the Instituto de Nutricion of Lima in this project. Analyses of 

 the data obtained are necessarily complicated, but in a preliminary 

 way the following conclusions are now apparent : Mean weight gains 

 as viewed longitudinally have increased 19-53 percent, depending on 

 the school year, since the school-lunch program started. Stature in- 

 creases do not appear to be similarly affected. Clinical signs of vita- 

 min and mineral deficiencies declined grossly from 1956 to 1961, and 

 mean hemoglobin levels are up from 13.16 to 14.24 gm/100 ml. Al- 

 most all the Vicos boys are within the normal serum calcium limits, but 

 21 percent are still low in vitamin A and 8 percent are low in serum 

 carotene. An analysis of the detailed metric data is proceeding, and 

 the bone density figures from the X-rays are expected to be available 

 in the near future.
