Summary 1. The surface tensions of solutions of eight normal monohydric alcohols have been determined by means of thedu Noüy tensiometer. 2. The lowering of the surface tension of water produced by each alcohol in the series depends on its position in the series. The factor 3 ofTraube's law is only approximate; generally it is greater than this, the average value over the range of alcohols studied being about 3·3. 3. Equi-toxic solutions of the different alcohols do not necessarily possess the same surface tension. 4. Although in the homologous series of alcohols examined, surface activity and toxicity run parallel, surface activity increases more rapidly than toxicity, proceeding up the series. Thus octyl alcohol is about 4400 times as effective in reducing the surface tension of water as methyl alcohol, but only about 2100 times as toxic.
