The white swellings in the limbs afflicted by infantile paralysis would appear to be excessively rare. Personally, I have never encountered one. It would be interesting to have indisputable observations, confirmed by laboratory examinations, of the white swelling which develops either in the well limbs of the subject of infantile paralysis or in a paralyzed limb of the same.
In case it is confirmed that there exists a certain antinomy between infantile paralysis and tuberculosis, it would be necessary to extend the experimental studies to the monkey inoculated successively by virus of poliomyelitis and by tubercle bacillus.
It would seem useful to determine in the first place if it is a question of a local immunity or of general immunity, and therefore one could also carry the experimentation to man, using both the serum obtained from a subject of paralysis and serum obtained from the animal.
