Philadelphia, March 15, 1897.
To the Editor:
—I am desirous of learning of the occurrence of muscular dystrophies, including pseudo-hypertrophic paralysis, idiopathic muscular atrophy, Erb's juvenile (scapulo-humeral) atrophy and facio-scapulo-humeral (infantile) atrophy of Landouzy-Dejerine, in colored persons and especially in those of pure, unmixed African parentage. I shall be grateful to receive information from any one who has encountered or has knowledge of cases of this nature. Respectfully,224 South Sixteenth St.
