PREFACE
adopted it, but I was unwilling to disturb the arrangement of the piece first written, and to some readers it is probable that the division may not be unacceptable.
Some highly important topics, in the third division of the volume, my experience, as the reader may conclude, would have enabled me to treat much more in detail, than the plan of this work permitted. It is difficult to speak im so small a compass upon subjects like those of cataract and artificial pupil, either of which is sufficient, from its extent and importance, to furnish materials for a distinct volume. I have endeavoured, how successfully I know not, to guard against material omissions, instudy- ing to preserve conciseness.
As I have made little reference to the writings of others, the omission of the sy- nonima forming the crabbed vocabulary of Ophthalmologists, ancient and modern, will, I hope, need no apology. ‘The nomen- claturing mania appears to me an evil of increasing magnitude.
