The Dalhousie University No. 7 "Overseas" Stationary Hospital was established in response to the need for qualified medical personnel required to serve in the First World War. It was first mobilized on November 9, 1915 at Dalhousie Medical College in Halifax. Balcom was involved as pharmacist and stock keeper for the second half of the war. In later years he was an active force in keeping the survivors in touch and organising reunion events.
Balcom kept a wide variety of items that indicated his involvement in associations and society generally. This series includes newspaper clippings, association lists that list Balcom on their boards, and keepsakes that do not otherwise fit into the other series.
The records in this subseries all relate to Balcom's career pharmacist whether pertaining to the operations of his pharmacy or the professional pharmacy organisations to which he belonged.
