CREOSOTE TEMP. VARIED Fig. 10.—The relation between absorption, penetration, and time of treatment using mixtures of creosoteNo. 4 and tar No. 5; also the comparative eSect of varying the pressure and time of treatment. PENETRANCE TESTS WITH CREOSOTE NO. 4 AND TAR NOS. 1 AND 5. Time of treatment and pressure constant and temperature varied.— (Tables 18 and 21 and figs. 11 and 12). Two series of tests on the effect of varying the temperature weremade, both on the penetrance apparatus. In the first series a mixtureof 50 per cent creosote No. 4 and 50 per cent tar No. 1 was used. Inthe second, 75 per cent of tar No. 5 and 25 per cent of creosote was used. Both the absorption and penetration were materiallyincreased as the treating temperature was increased. The testsindicated that temperature is an important factor in absorption and 1 Absorptions in these cases were about 9 per cent higher than with the creosote.
