The National Tuberculosis Association has undertaken to compile for each state, territory, the insular possessions and the District of Columbia, the laws, rules and regulations relating to tuberculosis and will publish them in separate pamphlets. These pamphlets will serve as a basis for comparative legal studies on various related topics, including isolation and quarantine of recalcitrant patients, establishment and control of sanatoriums, vocational rehabilitation and administrative functions of official agencies. One objective of this study is the formulation of model and uniform laws to reconcile the differences now existing. The pamphlet here reviewed, covering California, has recently been completed. Others will follow.
