    What are the modes in which infectious diseases manifest themselves ? By local and superficial disturbances (gonorrhoea); by local, followed by constitutional, disturbance (syphilis); by general disturbance, fol- lowed by local lesions (typhoid). What measures should be taken to prevent and limit the spread of infectious diseases ? Isolation of patient, proper ventilation of the room in which the pa- tient is confined, removal from the room of all articles not absolutely necessary; and thorough disinfection of the room and all articles which may have been brought in contact with the patient. TYPHOID FEVER. What is typhoid fever? An infectious disease whose special characteristics are lesions in the lymphatic glands of the intestines, mesentery, and spleen, and a roseolar eruption on the abdomen or chest. What is the cause of typhoid fever ? A specific, organized, pathogenic poison, appearing as a short rod- shaped bacillus with ends rounded off, generally found in colonies (foci) and multiplying by spores. The bacilli are propagated through sewer- gas, drinking-water, food, and dejections. The germs are introduced through the alimentary canal. When is typhoid fever most common as regards age and time of year ? Between the ages of fifteen and thirty-five years, and during the months of August to November. Give the pathological changes of typhoid fever? In the intestines Peyer's patches and the solitary glands are first en- larged and swollen, from irritation and inflammation caused by deposits of the typhoid virus. On the ninth or tenth day the infected glands ulcerate. If the case progresses favorably, they begin to cicatrize about the twenty-first day. The process of cicatrization generally lasts about two weeks. What are the most serious dangers to be feared from typhoidal intestinal ulcerations ? Extensive sloughing of the infected glands, causing septic general peritonitis or hemorrhage into the peritoneal cavity. Give the general course of the stage of incubation. It lasts two to three weeks; symptoms are ver}^ indefinite ; the patient has anorexia, headache (generally frontal), general pains, chilly sensa-
