This improvement continued until about two years later, when he again had a relapse, and was seen medically once more. His condition at this time was still a pretty good one, but the movements were stiff and awkward. The bin-iodid of mercury was advised, which was taken in doses of 9⁄25 grain daily. It will be remembered that this was long before the days of salvarsan treatment. This was toward the end of June, 1907. Contrary to expectation, there was no material gain from this treatment, and the patient died early in October, without being seen again. The =autopsy= was limited to the =nervous system= and the findings were as follows (Dr. A. R. Robertson): =Head=: Hair abundant, fair, of fine texture and rather curly. Scalp of medium thickness and strips readily from calvarium. The latter appears normal and upon removal is of about the normal thickness. It lifts readily from the dura mater, except for the numerous attachments of Pacchionian granulations. =Meninges=: The dura is smooth, moderately injected and shows no areas of thickening; it lifts readily from the pia-arachnoid. The pia-arachnoid shows discrete and in many places diffuse areas of opacity. There is a moderate amount of subpial clear fluid and the vessels are moderately injected. Over the anterior surface of the medulla and lower portion of the pons and largely confined to the right side there is a very marked thickening of the pia-arachnoid to which the dura is densely adherent. This thickening extends down anteriorly and laterally on the right side over the upper part of the cervical cord. The thickened meninges over the upper part of the medulla completely surround the right vertebral artery, shortly before it joins its fellow of the opposite side to form the basilar. Dissection of the arteries shows them to be patent and thin walled. Over the =cerebrum= and cerebellum the pia-arachnoid strips readily leaving a smooth surface. Section of the cerebral cortex, basal nuclei, pons and cerebellum show no gross lesions. The ventricles are moderately distended with fluid. The ependyma contains numerous small cysts. Section of the =pons= shows no lesions of the nervous tissue, but very marked thickening of the surrounding meninges as noted above.
