The move caused the Institution severe financial difficulties, which were compounded by a combination of declining funds from subscribers and increased costs from its growing student body. In 1873, the Directors turned to George Heriot's Trust for support, and agreed to a merger of the Trust's endowment with the Institution's own. The proposed merger was provisional to changes in the structure of the Watt Institution, which would see the organisation become a technical college with representatives of the Trust in management positions.
