186 Field Museum of Natural History — Reports, Vol. X 



The work in 1934 was conducted in the DeCandolle and Delessert 

 herbaria of the Conservatory and Botanic Garden of Geneva. These 

 well-known collections are so rich in type material that it was not 

 possible during the year to complete the photography of their types. 

 Mr, Macbride was aided most courteously by the director of the 

 Geneva institution, Dr. B. P. Georges Hochreutiner, who provided 

 every facility for successful prosecution of the task. Mr. Macbride 

 returned to the United States on vacation in September, but is 

 expected to sail for Europe early in 1935 to resume the work. 



As additions to the Herbarium of prints of type specimens have 

 continued, their great value for purposes of study and determination 

 has become constantly more apparent. That they are invaluable 

 for critical work upon the classification of tropical American plants 

 is evident to all systematic botanists, many of whom have had occa- 

 sion to study them. Prints from the type negatives are made 

 available by Field Museum to botanists generally in the United 

 States and other countries at the mere cost of production. During 

 1934 two American institutions purchased 1,609 prints from these 

 negatives. 



Partly as a result of this work. Dr. Charles Baehni, of the Botanic 

 Garden of Geneva, came to Chicago in August, 1934, to spend 

 approximately a year at Field Museum. His visit, at the invitation 

 of the Museum, will enable this institution to make some definite 

 return for the valuable material received in exchange from the 

 Geneva herbaria, and for the many courtesies extended by Dr. 

 Hochreutiner. Dr. Baehni is engaged in study of the Museum's 

 herbarium material of certain groups of plants in which he is 

 interested. 



From the Field Museum An Uii-opological Expedition to the Near 

 East, 1934, led by Assistant Curator Henry Field of the Department 

 of Anthropology, there was received a collection of approximately 

 8,500 herbarium specimens of plants. These were obtained chiefly 

 in Persia and Iraq. As these regions were previously almost without 

 representation in the Museum Herbarium, this material will be 

 exceptionally useful. Included are many duplicate specimens to 

 be used for exchange purposes. 



Throughout the year the Herbarium has been in constant use 

 by members of the staff of the Department of Botany. It has been 

 consulted also by a large number of visiting students from various 

 parts of the United States and from several foreign countries. The 

 Herbarium of Field Museum is the largest one west of the city of
