The average mortality from tubercular disease in mental hospitals is over nine times that of the outside population, and as regards dysentery, which is rarely met with among the sane community in this country, the Board of Control state that “during the second half of 1921 some 728 persons were attacked by the disease in mental hospitals and of these 126 died.” It is a most serious reflection that consequent on admission to a mental hospital a valuable life may be lost, such as, for instance, that of a young mother suffering from nervous shock after confinement, as a result of infection with one of these pathogenic organisms. It is therefore a matter of most urgent necessity that everything possible shall be done in order to eliminate dysentery from our mental hospitals and to reduce the mortality from tuberculosis; and now that the voluntary boarder principle is likely to be adopted for public mental hospitals it becomes more than ever necessary.
