 were held with officials of the physics and electrical engineering de- 

 partments of Union College regarding possible donations of apparatus. 

 From E. F. Hennelly, he obtained Dr. Albert W. Hull's kenopliotron,

Data and ideas useful in the planning for the graphic arts displays 

 in the projected exhibit halls of the Museum of History and Tech- 

 nology were obtained by Jacob Kainen, curator of graphic arts, on a 

 European trip extending from September 7 to 30, 1956. The museums
