The central nervous system is the seat par excellence of the virus of experimental encephalomyelitis of the Equidae. In the dog and the rabbit, the virus is encountered with an equal virulence in all the segments of the cerebral-spinal axis Ammons horn, chiasma of the optic nerves, quadrigeminal anterior tumors white substance of the orbital lobes and of the ceiling of the lateral ventricle arbor vitae of the cerebellum pyramids of the neck of the bulb, dorsal marrow, lumbar marrow, etc. In these experiments, guinea pigs inoculated in the brain with an emulsion of nerve substance taken from these various regions were all stricken with encephalomyelitis, without exception. Furthermore, the animals inoculated, under strictly similar conditions, with a marrow taken on the one hand from immediately behind the neck of the bulk, and on the other, from immediately in front of the tail of the horse, contracted the disease and succumbed within closely identical periods.
