sentence from ink in three different houses at about the same time,
and a variation may be observed in each. Thus old writing, if written
in separate places, will vary, unless, as was often the case, the writing
apparatus was carried about; but, where people wrote a great deal of
their correspondence at home, the colour of the ink will be singularly
uniform, and this is a test to be frequently relied on as to the
genuineness of the autograph.
