Стр. 138 - Regardless of whatever form of treatment may be employed, the removal of infection is imperative in all cases, whether the patient at the time may be well or ill. Where the health, comfort and usefulness of a patient are to be weighed over against a tooth, or even all the teeth, the greater interests of the patient must be preserved.
Стр. 421 - The diagnoses of these cases were made by the histories, by the clinical symptoms and manifestations, and by the demonstration of Treponema pertenue under the darkfield microscope in the cases where an open lesion was present, and by a careful history of those without open lesions, so as to remove any doubt as to the diagnosis.
