NOT many scientific text-books first published in 1887 have still a demand in the laboratories of to-day, at least in anything like their original form. In preparing the eleventh edition, Mr. Newth was probably well advised not to introduce physiology, whioh would, as he says, “have added greatly to its bulk, and the result could only have been a hybrid of very doubtful viability”. In its present form, the book is likely to retain its position as the standard work on animal morphology for junior students.
