The Structure and Classification of the Arthropoda

ABSTRACT [BY the great kindness of the proprietors of the tenth edition of the ‘Encyclopædia Britannica’ I have received permission to reprint in this journal the articles ARTHROPODA and ARACHNIDA, which I contributed to its pages. I have been anxious that morphologists should consider the views which I have put forward in these articles (written now nearly four years ago). At the same time I have observed that they have entirely escaped the notice of two authors who have recently written general essays on the Arthropoda, viz. Dr. A. S. Packard, of Salem, Mass., and Mr. G. H. Carpenter, of Dublin. I have revised both articles only in regard to verbal inaccuracies, excepting where I have definitely stated that new matter is introduced. I hope that in their present form these articles will not fail to come under the notice of zoologists.—E. R. L.]
