The proportions diffused are sensibly equal, of the different salts, at the higher 
temperature, with the exception of the largest proportion of salt, 10 per cent., when 
a certain divergence occurs. This last fact is consistent with our expectations, that 
the diffusion of salts would prove most highly normal in dilute solutions. Some of 
the irregularities at the lower temperature are evidently of an accidental kind. 
(2.) The neutral chromate and acetate of potash were diffused at a temperature 
ranging from 63° to 65°, or at a mean temperature of 64°* 1, which almost coincides 
with the higher temperature of the last experiments.
