CASE XXXII.* _Mercurio-syphilitic Cachexia._—Mr. L., aet. 27, had primary syphilis about four years ago. Subsequently had inveterate constitutional symptoms, for which he was under medical treatment both here and in Europe. When he had sojourned in the latter country some time, he was pronounced cured by his physicians. He married, and returned to this country in the fall of 1872. A few weeks after his return he fell into a gradual decline, which confined him to the house—and part of the time to bed—for eight months, during the latter portion of which he had discontinued all medical treatment. It was with difficulty that, assisted by his wife, he managed to reach my office. I found him terribly enfeebled; greatly emaciated; sallow complexion. He was much annoyed by rheumatic pains, which I considered specific. His condition was so exceedingly low, that I decided to postpone all medication until he should be stronger. I ordered galvano-faradic baths, i.e. the galvanic current in the bath as an eliminative, the faradic as a tonic. The first bath was taken on November 20th, 1873. For one month he took the baths, and nothing else. He was then so much stronger, that I felt justified in instituting a mild specific course of treatment, the baths being continued as theretofore. At the end of two months the patient was nearly as strong as ever, was able to resume his occupation, and had gained twenty-seven pounds in weight.
