Their monkeybecame paralyzed and thus they proved the possibility of theintestinal route of infection. Flexner and Lewis have success-fully inoculated a monkey by introducing the virus into the naso-pharynx after they had previously scarified the mucus mem-brane. This experiment admits of criticism on the ground that. Fig. 8.—Showing the adventitial infiltration of cells-immersion lens.
