112 SPECIAL SENSES. 



ence of a brother oculist. This would give the patient an 

 adaptability of the eye for different distances from twenty 

 feet (or parallel rays) to five inches ; or, in other words, an 

 accommodation of -J- (A = --), and a relative accommodation 

 for the very finest print from twenty. inches to five (A = g^). 

 My own range, measured at the same time, was from twenty 

 to five inches (vision being, in my left eye, exceptionally 

 large, ff ). 



"A careful examination of the pupils showed that they 

 were of the normal size, as were the movements of the iris 

 in every respect. With the ophthalmoscope, the pupillary 

 space was found in the right eye to be entirely free from any 

 remains of capsule, while, in the left, a narrow rim of the 

 whitened membrane just encroached on the upper pupillary 

 margin, but not to such a degree as to limit the size of the 

 pupil, and thus to act as a diaphragm. The media of the eye 

 were perfectly clear, and the. ophthalmoscopic appearances 

 were normal in every respect. 



" The patient promised to return, for the purpose of hav- 

 ing the reflections of the cornea measured by the optometer, 

 and the fact determined by the ophthalmoscope, whether, 

 under accommodative efforts, the eyeball became elongated. 

 This she failed to do, and the case, as stated above, was 

 shortly after reported to the New York Ophthalmological 

 Society, April 12, 1869, and, in July, 1SYO, to the American 

 Ophthalmological Society. In the index of the transactions 

 of the American Ophthalmological Society for that year, it 

 appears as a case of ' Apparent Accommodation in a Lens- 

 less Eye.' The paper, however, does not appear in the text, 

 having been withdrawn at the last moment, as there were 

 hopes that another examination could be obtained, and the 

 cause of the accommodation of the eye be definitely settled. 



" Two years later, Prof. Forster published a series of 

 similar cases 1 under the title of " Accommodative Power in
