Excerpt from Zoology an Elementary Text-Book In the eleven years which have elapsed since the publication of the second edition of this Text-book the science of Zoology has made such advances that it has become necessary to re-write considerable portions of this book. The brilliant work of Dr Goodrich on the nature and development of nephridia has caused us to reconsider our position with regard to the nature of these organs and we have now confined the name nephridium to the excretory organs of Platyhelminthes, Nemertinea, Rotifera, Annelida and Amphioxus, and have no longer applied the term to the excretory organs of Arthropoda, Mollusca and Brachiopoda. The chapter on Protozoa has had to be radically changed and we are indebted to Mr Dobell for valuable hints on this subject. The newer discoveries in the laws of inheritance are dealt with in the Introduction. The chapters dealing with Platyhelminthes, Nemertinea, Rotifera and Nematoda have been moved to a position following Coelenterata and preceding Annelida. A short chapter on Gephyrea has been added and the chapter on Arthropoda has been largely rewritten. In the second edition detailed accounts of a type of Arachnida and of Insecta were given - to these we have now added a detailed account pf the anatomy of the Crayfish as a type of the Crustacea, as experience has shown that only by the detailed study of types can the elementary student form clear images of Animals as going machines. Indeed throughout the book we have endeavoured to avoid describing structure unless function was indicated at the same time.
