referred to as Operation DEW I. The reference given is the document in Ref. 8 (Dugway Special Report 162).

• An operation named Operation DEW II, involving release of FP and Lycopodium spores from an aircraft. This is Dugway Special Report 179 ("An Experimental Study of Long Range Aerosol Cloud Travel Involving Ground Deposition of Biological Spore Material," F&MR Division, Camp Detrick, Frederick, Md., 1 June 1953) and appears to be the second (classified) document in Ref. 8 (not available).

• The Minneapolis, St. Louis, and Winnipeg trials are referred to as "Research Studies of Aerosol Cloud Travel over Cities." Contract DA-18-064-CML-2282, the Ralph M. Parsons Company. This appears to be the study examined in Ref. 35.

• Other referenced trials involving FP are Special Report 142. BW trials at San Francisco, Calif., Sept. 1950, PD Division, Camp Detrick, Frederick, Md., 22 Jan. 1951. "Studies in Aerosol Cloud Behavior." Contract DA-42-007-403CML-111, Chemistry Department, Stanford University, 1953.

There is a reference (p. 3) to the "St. Jo Munitions Expenditure Panel" that might indicate a named operation.
