During a recent service at the Children's Hospital there appeared a case which was rather puzzling as regards diagnosis. After some study I was able to classify it as an example of a disease little known in this country, which commonly goes under the obscure name of multiple cartilaginous exostoses. Further search brought to light roentgenograms of several other cases which represent the same affection. On the basis of this material I have begun an investigation of the condition, and later hope to present a thorough consideration of the subject. At this time I shall simply call attention to the matter by presenting briefly some of the salient characteristics of the disease, with photographs and roentgenograms of this patient, and photomicrographs of a specimen taken from an affected epiphysis.
The names given the affection are varied and confusing. The term most generally applied in English is the one already quoted, which was established by
