Aronson,3 using sixty- six grammes to i,ooo cubic feet caused the death of the tubercle bacillus immersed under several millimetres of broth, and anthrax spores exposed on gauze. Using thirty-three tablets per looo cubic feet, he succeeded in killing B. pyocyaneus, staphylococcus, typhoid, and diphtheria bacilli, but not anthrax spores, in every case. Prof. Grawitz considers 15 — 2 grammes per cubic metre (45 — 60 per 1000 cubic feet) sufficient in all cases except bed- linen, etc., which he st...ill disinfects with steam. The city hospital at Charlottenburg is now disinfected in this way. Harrington" states that the gas penetrates through dry pervious fabrics, but not always sufTicientlv to ensure ger- micidal action, and that when the fabrics are damp there is practically no penetration — see my results (/), p. 309. He concludes that formaldehyde should only be resorted to for surface disinfection. Inasmuch as the vapour is so soluble in water one would expect that materials previously moistened would absorb more of the gas than dry fabrics, and therefore show greater efficiency, as I found in my experiments.
