LAWRENCE (W.), F. R. S., &c. 

 A TREATISE ON DISEASES OF THE EYE. A new edition, edited, 



with numerous additions, and 243 illustrations, by ISAAC HAYS, M. D., Surgeon to Wills Hospi- 

 tal, &c. In one very large and handsome octavo volume, of 950 pages, strongly bound in leather 

 with raised bands. (Now Ready.) 

 This work is thoroughly revised and brought up to 1854. 



This work is so universally recognized as the standard authority on the subject, that the pub- 

 Kshers in presenting this new edition have only to remark that in its preparation the editor has 

 carefully revised every portion, introducing additions and illustrations wherever the advance of 

 science has rendered them necessary or desirable. In this manner it will be found to con- 

 tain over one hundred pages more than the last edition, while the list of wood-engravings 

 has been increased by sixty-seven figures, besides numerous improved illustrations substituted 

 for such as were deemed imperfect or unsatisfactory. The various important contributions to 

 ophthalmological science, recently made by Dalrymple, Jacob, Walton, Wilde, Cooper, &c., 

 both in the form of separate treatises and contributions to periodicals, have been carefully 

 examined by the editor, and, combined with the results of his own experience, have been 

 freely introduced throughout the volume, rendering it a complete and thorough exponent of 

 the most advanced state of the subject.
