26 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1959 
August 1, as guests of the Guatemalan Government, they were flown 
into Tikal, a great Mayan ruin being excavated and restored by the 
University of Pennsylvania. The travelers also made a quick trip to 
Lake Atitlan and to Chichicastenango. Because of his work on the 
living Indians in this area in 1947 and 1949, Dr. Stewart was inter- 
ested to observe the rate of acculturation here. As far as he could 
judge, there was very little change since his last visit. In Mexico City 
Dr. and Mrs. Stewart called at the National Museum and subsequently 
examined some promising fossil sites in the Valley of Mexico, where 
a new excavation is being made and a human skull was found at the 
Pleistocene level. During the visit to Mexico City Dr. Stewart ob- 
tained considerable information that will be of use to him in working 
for the Handbook of Latin American Studies and the projected Hand- 
book of Middle American Indians, 
Between March 25 and April 13, 1959, Dr. Stewart was detailed to 
travel to Czechoslovakia to act as the official U.S. representative at 
ceremonies honoring the 90th birthday of the late Dr. Ale’ Hrdli¢ka, 
who for so long was curator of physical anthropology at the Smith- 
sonian Institution. At formal ceremonies in Prague, Dr. Stewart 
had the opportunity to stress the fact of Hrdlitka’s American citizen- 
ship. In his address to the delegates he was able to point out that 
only in America could Hrdli¢ka have achieved his fame as an anthro- 
pologist. Later the celebration moved to Humpolec, Hrdlitka’s 
birthplace, 80 or 90 miles from Prague. Here Dr. Stewart and other 
delegates were taken through the loca] high school, which has been 
renamed for Hrdlicka. They also visited the site of his home, saw 
the street named for him, and visited various local institutions. Ata 
celebration Dr. Stewart again had an opportunity to say something 
about Dr. Hrdlitka’s life in America and the opportunity for scien- 
tific research in this country. On March 31 he participated in scien- 
tific meetings at the Institute of Anthropology at Charles University 
in Prague, on this occasion giving the delegates a report of his study 
of the Shanidar skeleton. This visit to Prague gave Dr. Stewart 
an opportunity to meet several of his colleagues whom he has previ- 
ously known by correspondence. On his return trip Dr, Stewart made 
a brief stop in Zurich to visit the Anthropological Institute. In Lon- 
don he visited the British Museum to examine the Mount Carmel 
Neanderthal remains, this visit providing him with a very profitable 
2 days of research. 
In March 1959 Dr. Lyman B. Smith, curator of phanerograms, vis- 
ited Cambridge, Mass., to study Herbarium material and to verify 
bibliographic references in the Harvard Herbarium in connection 
with his research on the family Bromeliaeae and the flora of Santa 
Catarina, Brazil.
