procurement and placement of accessions. 
ACCESSIONS 
New accessions totaled 122 objects from 40 sources. The majority 
of these were solicited by the Museum and involved considerable prior 
research by the staff to determine the significance and need of each 
object in the over-all picture of the history and development of aero- 
nautics. In addition, each accession required staff attention in a 
variable amount in arranging for the procurement and shipment of the 
object and in incorporating it into the aeronautical collection. 
Except where otherwise indicated the accessions received this year 
and listed below were entered in the Museum’s records as gifts or 
transfers:
