That «the results obtained by this method must be 
regarded as agreeing very closely inter sc, is shown by tile 
numerous salt- determinations performed with the same

These figures, it will be seen, differ but little inter 
se , and by increasing the quantity of water greater accuracy 
could no doubt be attained. 
For samples III and VII. the specific gravity at 
17.05 
respectively 1.01739 and 1.02669, bad been pre- 
viously determined by means of the pycnometer ; for samples 
IV, V. VI, and VIII, it was found by repeated readings 
of one of the corrected areometers, whereas for sample 
II it was determined by one reading only. The amount 
of chlorine, too.* in each sample was carefully determined. 
From these data may be computed the

It thus appears, that the coefficients both of chlo- 
rine and specific* gravity, notwithstanding the difference in 
the percentage of salt, are always very nearly constant;
