This edition is a reprint of the first in response to a continuous demand for the book. The matter, consisting as it does largely of records, does not call for any revision, and, as a contribution to the development of theory, any particular interest which it has is associated with the date at which it was written. The volume which has since appeared is the sequel, and aims at an exposition of the subject "to date". | RESEARCHES ON CELLULOSE 1895-1900 BY CROSS BEVAN C. F. CROSS AND E. J.
