THALMOLOGISCHEN GESELL­SCHAFT, 1936. Edited by A. Wagen­mann. Paper bound, Octavo, 530 pages,illustrated. Munich, J. F. Bergmann,1936.

Amid the international politics thrustupon us by the daily papers, it is good toknow that this scientific organization,formerly called the Heidelberg Congress,still carries on. The first session of thismeeting was presided over by Professorvan der Hoeve of Leiden, who receivedan honorary degree from the MedicalFaculty of the University of Heidelberg.Other sessions were presided over byMeisner of Cologne, Muller, of Basel,Brons, of Dortmund, Holtz, of Berlin,and Riehm of Giessen.

Forty-one papers were presented anddiscussed at this meeting, but among thereaders and discussers we find very fewwho have made the reputation of thesemeetings in the past. Notable by theirpresence were Lindner, of Vienna, Pillat,of Gratz, and Lauber, now of Warsaw,The papers presented were worth read­ing and discussing, and some of them willbe permanent additions to the literature.The first three dealt with heredity. Oehl­kers takes up hereditary eye conditionsfrom the biologic standpoint; von Ver­schuer from the medical standpoint; andWaardenburg reviewed the field of anom­alies, with reference to such charactersas dominance, recessiveness, consanguin-

ity, and so forth. The report of the dis­cussion on this symposium occupies 28pages.

A paper by Lauber and recent asso­ciates of Warsaw discusses the measure­ment of blood pressure in the retinalvessels, a subject that now seems to havea practical bearing upon the essential na­ture of glaucoma. Gasteiger, of Frank­furt a.M., on the histopathology of theeyes in renal-vascular disease, may alsothrow light on the same subject. Amongthe demonstrations were sections of tis­sue, with photographs of the patient, ina unique case-primary glioma of the or­bit, in a boy three-and-one-half years old.The tumor probably started in the opticnerve. There is nothing to indicate that itwas a retinoblastoma.
