2. If the clinical symptoms are insufficient in differential diagnosis, are not the pupillary signs and the speech defect of greater value? They are of value if present, but as in the case of Agnew, the victim of neurosyphilis may show no pupillary or speech disorder. Instances are familiar, also, in which the pupillary and speech signs are absent in very advanced cases of non-paretic or even of paretic neurosyphilis.

3. Would not a circular course or recurrence of attacks be decisive for manic-depressive psychosis? Paretic neurosyphilis sometimes exhibits the same circular or recurrent course. We conclude that neither the clinical symptoms, the classical pupillary and speech signs, nor the ups and downs of a particular disease, are at all decisive as between manic-depressive psychosis and paretic neurosyphilis. Resort must be had to laboratory tests.

4. What is the significance of the high blood pressure in paretic neurosyphilis? Work from our laboratory (Southard and Canavan) has shown plasma cells in the kidneys in 17 out of 30 paretics (56%), and in 16 of these 17 paretics with renal plasmocytosis, the plasma cells were found in the periglomerular region. What the relation of these findings may be to heightened blood pressure is as yet unknown. The severe syphilitic involvement of the aorta so characteristic in paretic neurosyphilis, as in other forms, may possibly have a bearing on blood pressure.
