congestion and edema of the ciliary body and permit pilocarpine to be more effective. All but one of the patients were women and all of the patients subsequently were treated surgically. The therapy appeared valuable in all patients but the intraocular pressure in one of the patients (Case 3) did not fall to normal until after peripheral iridectomy. Harvey Z. Klein 15330 S.

Editor American Journal of Ophthalmology: In the May issue of the JOURNAL Martin Kraushar and Frank Pardo described an ef fective way to produce attractive colored slides (Line copy presentation slides with Ektachrome. Am. J. Ophth. 73:790, 1972). There is a modification of this technique which we have been using in the Retina Lab oratory, Northwestern University Depart ment of Ophthalmology. It appears to be just as effective and precludes the need for special paper, particularly since Kodak is no longer
packaging their x-ray film with yellow pro tective sheets. We simply use ordinary type written material on white paper and place a Kodak Wratten No. 12 or a comparable filter in front of the lens to prepare the Ekta chrome negatives. A further advantage is that this technique can be used for all types of material (textbooks, journals, etc.) and is not limited to typewritten data.

BOOK R E V I E W S Edited by William S. Fields. New York, New York Academy of Sciences, 1971. Paperback, 386 pages, ta ble of contents, 171 black and white figures. $26 This Fourth Symposium on Myasthenia Gravis, held under the aegis of the New York Academy of Sciences, compiles recent devel opments in the basic and clinical sciences of this fascinating disease. A report of electron microscopic study con firms previous findings of a decrease in the nerve terminal area and post-synaptic mem brane profile concentration. Growing and re generating axons and immature appearing end-plates were noted. Further alterations in muscle fibers included migration of nuclei and mitochondria around abnormal capil laries, grossly thickened capillary basement membrane, changes in the contractual ap paratus of muscle fibers, nerve fiber damage to Schwann cells, myelin sheaths, and axons. Mechanisms of neuromuscular blockade, electrical re-activity patterns in the myas thenia syndrome (Eaton-Lambert), and other aspects of the physiology and pharmacology of synaptic transmission are also reviewed. The section on pathogenesis and pathoMYASTHENIA GRAVIS.
