This paper describes some histologic and histochemical characteristics of an easily transplantable islet-cell tumor of the Syrian hamster. The presence of insulin was demonstrated by means of fluorescent antibody and immunoassay technics. A positive histochemical reaction for tryptophan suggests, but does not prove, the presence of small amounts of glucagon. It is suggested that the tumor may be a useful tool for biologic studies.
