    ± STATE BOARD OF HEALTH. The full report makes an octavo volume of xi, 137 pages, of which only the conclusions reached by them from their experi- mental evidence is here published : CONCLUSIONS. The most useful agents for the destruction of spore-containing infectious material are : 1. Fire. Complete destruction by burning. 2. Steam under pressure. 110° C. (230° Fahr.) for ten minutes. 3. Boiling an, water for one hour.f 4. Chloride oflime.X A 4 per cent, solution. 5. Mercuric chloride. A solution of 1 : 500. For the destruction of infectious material which owes its infect- ing power to the presence of micro-organisms not containing spores, the committee recommends: 1. Fire. Complete destruction by burning. 2. Boiling in -water half an hour. 3. Dry heat. 110° C. (230° Fahr.) for two hours. 4. Chloride oflime.X 1 to 4 per cent, solution. 5. Solution of chlorinated soda.% 5 to 20 per cent, solution. 6. Mercuric chloride. A solution of 1 : 1000 to 1 : 4000. 1. Sulphur dioxide. Exposure for twelve hours to an atmos- phere containing at least 4 volumes per cent, of this gas, prefera- bly in presence of moisture. || 8. Carbolic acid. 2 to 5 per cent, solution. 9. Sulphate of coppjer. 2 to 5 per cent, solution. 10. Chloride of zinc. 4 to 10 per cent, solution. The committee would make the following recommendations with reference to the practical application of these agents for dis- infecting purposes : FOE EXCRETA. (a.) In the sick room : For spore containing material, ]. Chloride of lime in solution, 4 per cent. f This temperature does not destroy the spores of B. subtilis in the time men- tioned, hut is effective for the destruction of the spores of the anthrax bacillus and of all known pathogenic organisms. if Should contain at least 25 per cent, of available chlorine. § Should contain at least 3 per cent, of available chlorine. | This will require the combustion of between 3 and 4 pounds of sulphur for every 1000 cubic feet of air space.
