"The great feature of the volume is undoubtedly the series of
actual patterns of dyed papers, 157 in all--twelve of which, made
in England, have been added to the original German series. Detailed
formulae are given for the preparation of the pulp for each, and the
tints of the samples practically form a key, by means of which the
accuracy of the student's or practitioner's experiments can be
tested.... On the whole the publication is one of distinct
importance to the trade, and will no doubt speedily become a
standard work of reference amongst papermakers, both in the 'lab.'
and the office, as well as being an excellent text-book for the use
of students in the increasing number of technical institutes in
which papermaking is taught."--_World's Paper Trade Review._
