1. What conclusion can be drawn from lively knee-jerks? Lively knee-jerks are of very little significance. Not only certain neurosyphilitics but also a variety of neurotic persons, victims of dementia praecox and hysteria, are very prone to have active tendon reflexes. Of course, extreme degrees of exaggeration are of importance, and especially an association of the hyperreflexia with the Babinski reaction, the Gordon, or Oppenheim reflexes, ankle clonus, and the like.

2. Is there any special or differentiating factor in an extragenital chancre as against a genital chancre? Probably this question should be answered in the negative. Some have claimed that chancres draining by lymphatic channels of the head are more likely to lead to cerebral syphilis. This idea cannot be said to be established.

3. Is there any significance in the story, if true, that Phillips acquired his syphilis from a Mongolian? It seems to be fairly well established that syphilis of the nervous system is extremely rare in China and Japan, whereas bone syphilis is very frequent there. It has been held that this has to do (a) with strains of spirochetes, (b) with the state of civilization, or (c) with the degree of “syphilization.” Apparently when a race is first infected with syphilis the lesions are chiefly of the cutaneous and osseous systems; only in later generations the vascular and nervous systems suffer. However, involvement of the nervous systems of Mongolians resident in this country is no rarity, a point possibly in favor of the theory of special strains affecting the nervous system as prevalent in western countries. Little or nothing is known as to the effect of transmission from one race to another, as from Mongolian to Caucasian in Phillips’ story.
