Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It has been impossible to accomplish this without some sacrifice of uniformity of treatment and of logical sequence. This is especially noticeable in the chapter on the nervous system, which has been made much fuller and more practical than is usual. The author's reason for the method of treatment there adopted and for the considerable amount of anatomy which this chapter contains is the apparent success the method has met with in the teaching of this always difficult subject to st ants.
