Director' s A^uuial Report. 49 



their positions in exhibition cases or with the duplicates for ex- 

 change or the reserve for study. Next comes the Lunch room, 

 25.5X19 feet, a great convenience, as the members of the staff 

 live miles away from the Museum. Next in order is the Instru- 

 ment room, 25.5X12.5 feet, where are kept the phonograph and 

 its records, testing machines, electro-photo-micrographic camera, 

 X-ray apparatus, and many other appliances used in examinations 

 or researches. The corner room, 25.5X19 feet, is devoted to the 

 Curator of Pulmonata, and here are the best known appliances for 

 cleaning, cataloguing and storing our vast colledlions of Hawaiian 

 land shells, and also for studying the builder of the shell as well. 

 Other pages of this report will show what extensive use the Cura- 

 tor makes of this. Across the hallway is the large room set aside 

 for Marine Zoology, and from the middle of the hallway a flight of 

 stairs leads up to the roof level, a third of which is occupied b^^ 

 the Photographic department, 24.5X55.5 feet. The most com- 

 fortable Dark room that has been devised for a hot climate is pro- 

 vided with earthen sinks, a tank for washing bromide prints, three 

 windows with orange and rub}^ sashes, convenient apparatus for 

 enlarging, elecftric printer, ventilators passing a suflficient air cur- 

 rent through the room, and the other usual appliances of these 

 work rooms. The Light room has a supply of cameras, back- 

 grounds and stands and racks for the quick adjustment of objects 

 to be photographed. The lighting is all that could be desired, and 

 the ventilation is provided by suitable openings in the top of the 

 walls and by two doors opening onto the roof. As nearly all the 

 staff are expert photographers and a great deal of photographic 

 work is done both for record and for illustration of publications, 

 this room and its equipment are ver}- important adjuncts to the 

 laboratory. 



White cedar cases with glass doors line all the hallways; a por- 

 tion of the lower hall is occupied by the collecftion of Hawaiian 

 and South-east Pacific fishes in alcohol, many types among them.
