To the Editor:—
From August 1929 to August 1931, more than 1,000 autopsies were performed in Haiti under the observation of J. H. Chambers, Commander, Medical Corps, U. S. Navy. From this group, material from more than 200 cases showing some aortic change or evidence of yaws-syphilis in other organs was forwarded to Prof. A. S. Warthin of the Department of Pathology at the University of Michigan for further study (Chambers, J. H.: Review of the Pathology Observed in 1,018 Postmortem Examinations in Haiti, U. S. Nav. M. Bull.34:285 [July] 1936).Professor Warthin began the study, but owing to his death the work was continued by Professor Weller.

Dis.20:467 (Sept.) 1936; The Visceral Pathology of
