78 REPORT OF NATIONAL MUSEUM, 1918. 



getting material for this purpose, correspondence with different per- 

 sons in the State of Washington resulted in the obtaining by dona- 

 tion from Mr. Alexander Gardiner, of North Bend, of a section of 

 a cascara sagrada tree 3 feet long, and 16 small photographs 

 showing the method of gathering the bark and preparing it for 

 market. Dr. C. W. Johnson, dean of the College of Pharmacy, Uni- 

 versity of Washington, Seattle, also assisted in the matter by fur- 

 nishing 21 small photographs depicting the progressive steps in ob- 

 taining and shipping the bark. 



While steps were taken in April to install the exhibition series of 

 the division on the south side of the gallery in the east hall of the arts 

 and industries building, the exhibit was not sufficiently advanced at 

 the close of the year to be open to visitors. The general subjects to 

 be illustrated are: History of Medicine, Materia Medica, Phar- 

 macy, and Sanitation and Public Hygiene, and they appear in the 

 series in the order named. Three alcoves are given to the history of 

 medicine. Into the cases of the first alcove have been placed the 

 specimens which illustrate an historical development in the magic, 

 psychic, physical, and physiological treatment of disease. The 

 second alcove is made up of the collections relating to the history of 

 Indian, Egyptian, Hebrew, Greek and Boman, and Chinese medi- 

 cine. The history of medicine in America is presented pictorially in 

 the next alcove in the form of biographical sketches and photo- 

 graphs of prominent medical men since the settlement at Jamestown. 



Materia medica, materials used in medicine obtained from ani- 

 mal, vegetable, and chemical sources, is illustrated in the next three 

 alcoves. 



The last two alcoves on the south side, east end of east gallery, 

 will be devoted to the history of pharmacy and modern medicinal 

 forms. Of sanitation and public hygiene, a beginning was made by 

 illustrating, at the eastern end of the gallery, the composition of the 

 human body, the composition of milk and bread, a dajr's rations, and 

 the utilization of food. 



Considerable was done during the year in the way of examining 

 and inventorjdng the medical collections comprising the study series, 

 but this had to be put aside for the time being, as the installation of 

 the exhibition series was of first importance. It was found that 

 some of the materials from older collections had deteriorated to such 

 an extent as to be worthless. While it is believed that all such can 

 be replaced, a definite statement can not be made in advance of the 

 completion of the inventory, work on which will be resumed as soon 

 as possible. 



Representatives of the Bureau of Chemistry, Department of Agri- 

 culture, have at various times examined and studied material in the 

 division, and specimens of Datura alba, Virola guatewnril-ensis, and
