PREFACE.

The subject of Injuries of the Eye forms part of the systematic treatises on diseases of this organ, but I am not aware that any English work has been specially devoted to the subject; when in charge of difficult and anxious cases I have often felt the want of such a book of reference as that I have now endeavoured to supply.

The members of the medical profession, especially those of matured experience, must be conscious of the progressive character of knowledge; and on surveying the various theories and changes of opinion they have witnessed, will feel that the information they possess is but a drop in the great ocean of truth.

Deeply sensible of this, the present volume is put forth by me with the consciousness of many shortcomings and imperfections; nevertheless, it is hoped that it may prove useful: to render it practical no pains have been spared.

Believing that cases are not only illustrative but impress facts upon the memory, they have been freely introduced in a concise form, and limited as far as possible to the leading points.

Though unavoidably enhancing the cost of the volume thereby, I have availed myself of the skill of Mr. Sherwin, to insure fidelity in the colouring of the plates, which, with the woodcuts, are from my own drawings. The cuts have been executed by Mr. William Bagg and Mr- Orrin Smith.

My grateful acknowledgments are due to the following gentlemen, who have courteously afforded me information— Mr. W. Wale Tayler, St. Austell; Mr. Edward Robathan, Risca; Mr. David Hughes, sen., Llangollen; Mr. John Williams, Mold; Mr. Peter Squire, and Mr. Lloyd Bullock.
