 thalmoscopic Surgery, June, 1863, apologising for the imperfections 

 of the diagrams illustrating their works, state that it is impossible to 

 procure the services of artists having the requisite knowledge of the 

 use of the Ophthalmoscope.

 can be taken showing the details of the fundus of the eye. 



In conclusion, I would express the hope that the invention of this 

 instrument will contribute something towards popularizing Ophthal- 

 moscopy, as, in investigating diseases of the eye, the Ophthalmoscope

 blind."
