| Abstract: | Summary The toxicity of eight normal aliphatic alcohols towards potato tuber tissue has been compared by following the rate of exosmosis of electrolytes into solutions of each of the alcohols of various concentrations. Solutions are regarded as equi-toxic which bring about the same rate of exosmosis under the same conditions. With each increase of one carbon atom in the carbon chain the toxicity of the alcohol is increased from 2·25 to about 4·7 times. Normal octyl alcohol is thus more than 2,000 times as toxic as methyl alcohol. The extent of agreement of these results with the theories ofTraube andCzapek is indicated. |
