    closely in contact, somewhat piled up, giving the general im- pression of the mulberry-like appearance which has been * attributed to the so-called colloid growths seen in the nerve- head. Each patch is a large oval three disc diameters in length and two in width. The amplitude of accommodation, after correction of the refractive anomaly, is normal. There is an exophoria of four degrees. The visual field is normal and there is no scotoma. The appearances of the right eye are represented in the accom- panying water-color; those of the left are practically the same.* This patient was first seen more than four years ago, and has been examined on numerous occasions since that date, the last time only two weeks ago. There has never been the slightest change in the appearances of the spots, and never the Jeast disturbance of central vision, which at the present time is 6/5. Case II. — Louise N., a young unmarried woman, presented herself for treatment on account of persistent asthenopia and frontal and occipital headaches, which have been temporarily relieved by glasses. Her refractive error was first corrected six years ago, again two years ago, and lastly two months ago by myself. Father and mother are healthy, but the patient has never been very strong. When five years old she had measles severely and also chicken pox, but never scarlet fever. Seven years ago she was very ill with what was supposed to be acute anaemia. She improved under the influence of rest-cure and massage. At this time, however, it was discovered that the urine was loaded with albumin and contained numerous hyaline and granular tube-casts. These have persisted, al- though at the present time the quantity of albumin has greatly lessened and the general nutrition of the patient has much im- proved: The vision in each eye is 6/9, which, after the correction of a compound hypermetropic astigmatism, O. D. -f- .50s C + 50C axis V. O. S. + .50s C + 62c axis V. rises to 6/6. * I have seen a third case, exactly like the ones I report, through the courtesy of Dr. John T. Carpenter, Jr. The water color of this case, by Miss Washington, has not been repro- duced.
