Garson, of Cambridge, a well-known zoologist and anatomist. This book, to be properly appreciated, should be studied in connection with the series of homologous bones of different species of mammals arranged by Flower himself in the museum of the College of Surgeons, to which reference has been made in an earlier part of this chapter, and from which most of the illustrations were drawn. The figures of the dog’s skull have been reproduced in a large number of zoological and anatomical works. The plan followed in this volume forms an admirable model for all works of a kindred nature. In the first chapter the author discusses the classification of the mammalia; in the second he describes the skeleton of that group as a whole; while in the remainder the modifications presented by the various bones in the different groups are described in considerable detail. A special feature is the sparing use of technical terms, and the careful explanation of the meaning of those of which the use was unavoidable. Besides being carefully revised and brought up to date, the third edition differed from its predecessors by including a table of the number of vertebræ found in a large series of species. In the following year (1871) the Hunterian course, which comprised no less than eighteen lectures, was devoted to the functions and modifications of the teeth of mammals, from man to the monotremes, although it was not known at that time that either of the two generic representatives of the latter group really possessed true teeth, the discovery of these organs in the Australian duckbill not having been made till many years later. Among other subjects included in his Hunterian lectures was the anatomy and affinities of the Cetacea, or whales and dolphins, a group of mammals in which Flower almost from the first displayed a marked and special interest, and on which he became one of the first authorities. Since, however, this is a subject to which fuller reference is made in a later chapter, it need not be further discussed in this place. In 1872 Flower’s Hunterian lectures were devoted to the subject of the digestive organs of mammals; these lectures being reported, with illustrations, in the _Medical Times and Gazette_ of the same year. Perhaps the most important and certainly the most voluminous of these lectures was the series on the “Comparative Anatomy of Man,” which extended over several years, the course for 1880 dealing especially with the skulls of the Fiji, Tongan, and Samoan islanders. The subject of anthropology, or the study of the different races of mankind from a zoological standpoint, shared indeed with that of the Cetacea a large part of the Professor’s attention, and the two together formed, perhaps, his favourite lines of investigation. In regard to the problems presented by the human race when viewed from this standpoint, Flower has expressed himself as follows:—
