Abstract
THIS is a kind of pictorial analytical table in which the characters of the precipitates obtained are indicated by coloured oblong spaces, which will, doubtless, be found very useful for impressing the appearances of the different precipitates on the mind of the student. The borax bead obtained with a compound of cobalt is represented by a blue oval, and the effect of ammonia on red litmus paper is shown by an oblong half red and half blue. The changes of colour produced by the action of sulphuretted hydrogen on a salt of mercury are indicated by an oblong of four different colours, white, yellow, orange, and black.
