IY.—Each photograph sent in for registration should hear a local number, 
and the accompanying form should be numbered in accordance therewith. [The 
space on the right-hand bottom corner is for the use of the Committee.] 
V.—Lists of photographs, copies of photographic prints, and informatibn 
relative thereto, should be sent under cover to the Secretary to the Committee,— 
Mr. Osmund W. Jeffs, 12, Queen’s Road, Rock Ferry, Cheshire,—at the earliest 
possible date, as the work of registration will be heavy.
