"East wing, third story, " 

 from United States Na- 

 tional Museum Bulletin 

 80 (1913). This laboratory 

 of invertebrate paleontology 

 cannot be precisely located, 

 but the geyieral area, now 

 occupied by archeolo gists, lies 

 more or less under the section 

 of roof shown in picture on 

 page 36. The negative is 

 stained, and the effect seen 

 on the wall is not that of a 

 leaking roof. The woman 

 using the typewriter, barely 

 visible behind cabinets, may be 

 Margaret Moodey, secretary 

 of the Department of 

 Geology.
