parasites; Dr. L. A. Faustino of the Philippine Bureau of Science 

 spent considerable time in the division in the study of Philippine 

 corals and mollusks; J. Edward Hoffmeister continued to work up 

 the Samoan corals collected by Dr. A. G. Mayor. 



Many professional botanists from outside of Washington have 

 visited the herbarium during the year. Among these may be men- 

 tioned: Prof. H. Pittier, of Caracas, Venezuela, who spent several 

 weeks in a study of material from northern South America, chiefly 

 specimens of his own collecting in Venezuela ; Prof. L. H. Bailey, of 

 Ithaca, 1ST. Y., who spent a fortnight in identifying critical material 

 of his recent collections in Brazil, Venezuela, and the Lesser An- 

 tilles ; Alwin Berger, of the staff of the New York State Agricultural 

 Experiment Station, Geneva, N. Y., in examination of herbarium 

 material in connection with monographic work upon the small culti- 

 vated fruits of temperate regions ; Miss Caroline C. Haynes, of High- 

 lands, N. J., in connection with the preparation of a. report upon 

 an extensive collection of Louisiana specimens of Hepaticae intrusted 

 to her for elaboration; Dr. T. Nakai, assistant professor of botany 

 of the Tokyo Imperial University, who gave special attention to the 

 identification of certain early collections of Japanese plants by 

 Charles Wright; Edwin B. Bartram, Bushkill, Pa., who has made 

 recent large collections in the southwestern United States, and is 

 particularly interested in the succulents and mosses of that region; 

 A. V. Fric, of Prague, Czechoslovakia, in connection with a study of 

 the Cactaceae of Mexico, of which he has obtained large series 

 through personal field work; Prof. A. W. Sampson, of the Univer- 

 sity of California, in connection with the preparation of a paper on 

 the forage grasses of California ; and Miss Ena A. Allen, of Grubb's 

 Vocational College, Arlington, Tex., who was engaged in the prepa- 

 ration of a paper on the grasses of Texas. 



Allusion to loans of specimens to institutions and investigators for 

 aid in the study of their own material has been made above in several 

 instances, especially where the National Museum was incidentally 

 benefited by their studies. This, needless to say, is almost always the 

 case, to a greater or less degree, when the material is used by expert 

 specialists, whose critical remarks and identifications are highly 

 valued. The extent to which such loans have been made at the re- 

 quest of the investigators will be seen from the following list : Mam- 

 mals were loaned to the American Museum of Natural History, New 

 York, for the benefit of Dr. W. K. Gregory and H. E. Anthony; 

 British Museum, London, for Oldfield Thomas; Dr. G. B. Wes- 

 locki, Johns Hopkins Medical School, anatomical material to be used 

 in histological studies; Dr. C. J. van der Klaauw, Leiden, Holland, 

 embryological material ; Field Museum of Natural History, Chicago,
