The interaction of a stream of dielectric spheres in an electric field in a high vacuum is investigated both theoretically and experimentally. Underlying this investigation is an attempt to detect fractional electric charges which might exist in matter, that is, isolated quarks. The theoretical analysis is intended to pinpoint the basic interaction mechanism by which a stream of dielectric spheres becomes destabilized in an electric field. One important result of this analysis is a method by which the destabilizing forces can be eliminated. The experiments study the behavior of a stream of uniform liquid drops in an electric field in a high vacuum. It is seen from these experiments that the deflections of any two drops in the stream with charges differing by one electronic charge is the same except for the effects of some destabilizing forces.
