Observations on the relative density and thermal expansion of propyl alcohol have 
been made by Pierre and Puchot (‘Annales de Chim. et de Phys.,’ (4), 22, 276), 
and by Zander (‘Annalen,’ 214, 154). The observations are not in very good 
agreement. As there seemed to be doubt as to the individuality of the specimen of 
alcohol employed by Pierre and Puchot, the numbers given by Zander have been 
adopted, viz. :— 
V = 1 + -0374601^ + -0549478^2 + -0713929^3. 
We have also employed his value d (0°/0°) = 0‘8177 for the relative density. It 
happens to be the mean of the observations of Bruhl and Linnemann. 
Taking 
7 ]^ — -031452 7 ]^ = -004990 
^^= 7°-31 ^3 = 93°-]0 
we obtain the formula 
8801350-0 
“ (135-75 + 0* ’ 
which gives the following observed values :— 
7 ].2 (calculated) = -012527 
^2 (from curve) = 45°-19,
