of feet of splendid motion pictures of the animal life. The work of 
the Eastman Kodak Company on the island, and in Panama City, 
is yielding most valuable data on corrosion and deterioration, as 
well as a better understanding of the influence of the Tropics on 
color film. 
EK. P. Killip, head curator of the department of botany, United 
States National Museum, spent a short time on the island, collecting 
material for the herbarium. He went over most of the laboratory’s 
herbarium specimens and later will send such additional sheets as 
may be needed to augment or supplement the collection. 
Dr. Charles C. Adams, pioneer ecologist of the Americas, was 
another visitor who came to the Tropics for first-hand knowledge. 
He stressed the value of the island for ecologists, both plant and 
animal, in providing an intimate acquaintance with jungle life. 
Dr. and Mrs. H. N. Moldenke, of the New York Botanical Garden, 
visited the island after their return from the Second Pan American 
Botanical Congress held in Tucum4n, Argentina. Dr. Moldenke’s 
chief interest was the Verbenaceae, and he very kindly rechecked the 
laboratory’s material in this family. 
Dr. Marshall Stone, of the University of Chicago, again revisited 
the island for a short time. 
Phil W. Longenecker, student at Colorado College, spent the month 
of July on the island. He made a list of 98 species of birds that he 
positively identified, with copious notes on their habits. His 
studies also included observations on a number of the mammals. 
In his report he states that he did not find it necessary to go far into 
the forest, as there was so much to see within a mile of the laboratory. 
Dr. Eugene Eisenmann, of New York City, visited the island again 
this year to continue his ornithological studies. Dr. Eisenmann is 
an authority on the birds of this region. He will prepare a list, 
brought up to date, of the birds observed on the island. 
Oliver E. Mosser, of Smithtown Branch, N. Y., came for a few 
days, specifically to make certain important observations of army 
ants for Dr. Schneirla. In addition he studied birds and mammals. 
Frank W. Hunnewell and his sister Louise revisited the island and 
stayed several weeks, following up his botanical studies. They 
showed the same deep interest in the island that they had displayed 
ever since Dr. Barbo:ir was actively connected with its direction. 
lt is a pleasure to record again a short visit by Dr. and Mrs. 
Matthew W. Stirling and Richard Stewart, who were in Panama on 
archeological reconnaissance on behalf of the National Geographic 
Society and the Smithsonian Institution. Motion pictures were 
taken by Mr. Stewart to complete the reel covering the island. 
Dr. Wetmore, Secretary of the Smithsonian, revisited the island,
