    that these hints may, at least, have the effect of leading- students to adopt a practice that will be found to be of great value, even beyond the subject to which it is applied. I have had, in this edition, the help of Mr. Marcus Gunn, who has conferred on the work the advantage of a final revision, and has also superintended its passage through the press. To his knowledge and care the reader is largely indebted. I may add the following extract from the preface to the first edition, published in 1879:— With one or two exceptions all the cases described and figured were met with in the course of purely medical work, chiefly at University College Hospital, and at the National Hospital for the Paralysed and Epileptic. In the preparation of the illustrations, great care has been taken to secure the utmost possible exactness. The autotype plates are repro- ductions of sepia drawings; and this method has been chiefly employed because by it a more exact representation of delicate pathological appearances can be obtained than by chromo-lithography. This method has also the advantage of fixing the attention on the changes of form, rather than upon the alterations in colour, which, important as they are, very often mislead the inexperienced. Chromo-htho- gra'phy has been employed for some subjects in which the changes of tint are of predominant importance. It is intended that the autotype plates should be studied by the aid of the descriptions prefixed to them, and it is believed that, thus examined, those who are accustomed to the use of the ophthalmoscope will not miss the absent colours. With one or two exceptions, specified on p. 305, the drawmgs were all made by the direct method of examination. W. R. GOWERS. 50, Queen Anne Street, Juhj, 1890.
