Two experiments are reported in which rabbits originally inoculated with syphilis and treated late in the course of the disease (174th to 210th day) were reinoculated subsequently in both corneas with the homologous strain of syphilitic virus. In each animal one cornea was inoculated with dead tubercle bacilli prior to reinoculation with the syphilitic virus. This procedure was carried out in order to bring about a non-specific inflammatory reaction with resultant vascularization, the intention being to find out if such vascularization would render the cornea more resistant to inoculation with the homologous strain of syphilitic virus. The results of both experiments were similar and while they were not conclusive, they indicated that there was a tendency for corneas which had been injected with dead tubercle bacilli to be more refractory to a subsequent inoculation with homologous syphilitic virus than the corneas of the same animals that had not been injected with dead tubercle bacilli. This tendency may be interpreted as suggestive evidence for the view that in the syphilitic rabbit there develop circulating antibodies toward the homologous strain of T. pallidum.
