2. Detached pavilions of _hospitals for infectious diseases_ have also been employed for the treatment of tuberculosis, and experience has demonstrated that in well-conducted institutions consumptives are not exposed to risk of acquiring acute infectious diseases. The use of these institutions favours economy of administration. It possesses the advantage that patients are, as a rule, more accessible to their relatives than in a sanatorium; and this renders patients suffering from progressive disease more willing to remain in the institution than they would otherwise be. Patients can advantageously be placed in such an institution for observation, before deciding whether prolonged treatment in a distant curative sanatorium is indicated. Occasionally empty _smallpox hospitals_ have also been employed for the institutional treatment of tuberculosis; but if this plan were to be generally adopted, tuberculosis work would be seriously crippled if smallpox became epidemic. The treatment of consumptives in a smallpox hospital should only be permitted for patients who could be at once transferred and who can be at once vaccinated. _General hospitals_ are well fitted to deal with the following classes of cases of tuberculosis: (_a_) Patients admitted for observation, with a view to diagnosis; (_b_) Patients admitted to ascertain the form of treatment best adapted for the patient’s needs; (_c_) Emergency cases, e.g., haemoptysis; (_d_) Patients requiring surgical aid for intercurrent diseases; (_e_) Patients with advanced disease admitted for special purposes; (_f_) Patients with non-pulmonary tuberculosis, requiring special surgical treatment. In approving arrangements for the treatment of pulmonary tuberculosis in a general hospital, it should be made a condition that they shall not be received into general wards of the hospital in which there are persons suffering from other diseases, unless for a sudden emergency, or for a short period for operative treatment, or unless there is no expectoration, or if this, on repeated examinations has been found to be free from tubercle bacilli. _Sanatoria and Combined Institutions_
