two years, and in his opinion refractionists have overlooked an opportunity to give relief by this sort of treatment and thereby not only give satisfaction but pre vent certain patients from making the rounds among us, saying this doctor does not know how to fit glasses, and so forth. His theory in giving these exercises is that we create new or stimulate normal fields of function. We have to have a cer tain amount of reserve. We are on the way to giving comfort in the refractions of the asthenopic. Dr. H. L. Bair, of Rochester, asked: "How valuable are those peripheral stim uli?" Dr. Walter H. Fink, in answering, said, "Three years ago I had occasion to look into the matter of peripheral fusion in detail and obtained a fairly good knowledge of the literature on the subject and, in addition, did some experimental work. I came to the conclusion that peripheral fusion has a definite value, perimacular fusion, however, being of greater importance. "I have used the rotoscope for several years and I believe that it brings to light certain phases of the muscle problem that you cannot obtain on the phorometer. Stereoscopic vision can be employed on the rotoscope, and it is of definite value in determining the degree of ocular co ordination. It would be of great value to determine not only the presence of stereoscopic vision, but also the degree. It seems to me that patients who have a high degree of stereoscopic vision have far more ocular reserve power." George McGeary, Secretary- Treasurer.

OCULAR BRUCELLOSIS
Dr. E. L. BURKY (Johns Hopkins Hospital, Baltimore) read an interesting paper on this subject. He said that Brucella (species undertermined) has been recovered from the milk, blood, spleens, and lymph glands of six mares killed because of blindness due to clinical periodic ophthalmia. This is a recurring iritis or uveitis with all the clinical features and sequelae observed in this condition as it appears in the human. When injected into the anterior cham ber of rabbits, or intravenously into rab bits and guinea pigs, the first strain that was recovered produced in some but not in all animals ocular inflammation resem bling periodic ophthalmia in horses and chronic recurrent ocular inflammation in the human. After these rather striking experimen tal results had been obtained in animals, an investigation was begun to determine whether this bacterial genus could cause human eye diseases. Fifteen cases in which there was some evidence of this infection had been studied. The evidence is based on four tests: 1. Complement fixations with Brucellin as an antigen. 2, Opsonocytophagic tests with living cultures as an antigen. 3. Agglutination tests with the same antigens. 4. Cutaneous reactions to Brucellin. The ocular lesions observed included recurring keratitis, iritis, and keratoiritis, and tuberculouslike lesions in the fundus. Virgil G. Gasten, Recorder.
