    some nine months before coming to me. He or- dered : R. + Sph. 2.ooPrism 2° B. I. L. -j- Sph. i.5oPrism 1.5° B. D. This order was as bad as if it had been made by “the leading oculist of the city.” Without a mydriatic I estimated the error of refraction to be: R. + Sph. 1.62 -f- Cyl. 0.62 ax. 180° = 20/50-I- L. -f Sph. 1.37 4- Cyl. 0.37 ax. 180° = 20/30? 2° B. L, 1° B. D. L. There was also evident subnormality of accommo- dation. With paralyzed accommodation the errors were found to be: R. -f- Sph. 2.00 H- Cyl. 0.50 ax. 180° = 20/50-I- L. + Sph. 2.00 -j- Cyl. 0.37 ax. 180° = 20/30? With all the woman’s good will to do as advised she could not and would not try bifocal spectacles, because she had by bitter experience demonstrated that they only increased her symptoms. This fact was a hint to my mind, and one which stuck there, that there was in this case an unsolved problem. I gave proper distance glasses with “fronts” for near, but the “unbearable pain” lessened no whit. In a few weeks the error was not different, and I * demanded bifocals, to be used at meals, and in the house. She vowed she “could not see with them.” I did not then suspect the reason they increased dif- ficulty and pain, but this became apparent when with search and study I found that she closed the right eye when reading and ignored its image for distance, and that she “had done this for years,” as she now confessed. I was now on the heels of the mystery. At the first visit in using the ophthalmoscope I spoke of a curious loop in the superior tem-
