A manual and atlas of medical ophthalmoscopy

,, aPPended are for the most part those of which

the ophthalmoscopic appearances are figured in the plates. A few others, which furnish examples of important facts, ave been added. The majority are published now for the rst time. Many are suggestive in their medical as well as in their ophthalmoscopic aspects, and, since the work is designed especial y for medical workers, the general symptoms are arrated, and m some cases their significance is briefly pointed out. The descriptions of the cases have been ab^

n the preparation of the systematic part of the wo-k I have been much indebted to the writings of Dr. Hurf,hn*s- Jackson, the value and suggestiveness of which it i f difficult to ex erate to D, Clifford Allbutt’s important work on

]iis practical work, in the medical and -surgical wards, and in the medical out-patient room, supplies liim with opportunities for practice and education in the use of the instrument, and the study of the various aspects of the normal fundus, without any interference with other work — opportunities, which, if lost, rarely return, and are not to be found in the practice of the ophthalmic surgeon. I think, indeed, that a perusal of the account contained in the following pages of the large number of diseases in which significant changes in the eye are common, will support the opinion that the condition of the fundus should be systematically described in medical case-taking, and it is only by early education in the use of the ophthalmoscope that such a result can be obtained.
