SOME FACTORS DETERMINING THE LOCALIZATION OF A CHICKEN TUMOR AGENT

Abstract
Scharlach R, kieselguhr, tar, and hashed chicken embryo tissue are able to determine the localization of the Rous chicken tumor when these irritants are injected at such an interval before injection of the infecting agent that the reaction due to the irritant is at its height when infection occurs. Kiesel-guhr is the least effective.
