BACTERIA THERAPY, the treatment and prevention of disease by inoculation with the virus of the bacteria causing the dis- It was first practiced by Dr. Edease. ward Jenner toward the end of the 18th century. He made the discovery that persons inoculated with cowpox were thereby rendered immune against smallpox. Since that time the practice has been extended to several other diseases, including typhoid fever, asthma, and pneumonia, and it is claimed that in most cases the results have been remarkably successful. Care should be taken to distinguish between SERUM THERAPY (q. v.) and vaccine therapy. In the former, anti-toxins are injected into the blood to assist in the destruction of the toxins which cause the diseased condition. In the latter, bacteria themselves, or their products, are introduced into the blood, the theory underlying the practice being the stimulation of the natural healing powers of the body, by the formation of anti-toxins, thus producing greater resistance to disease. Human serum possesses what is known as opsonic action on bacteria, which means that it renders them more easily destroyed by the white corpuscles in the blood. The power which the serum of a patient displays toward bacteria is known as the "opsonic index" (see OP- SON) and it has been found that when the opsonic index is rising, favorable results can be produced by vaccine injection, but when the opsonic index is falling, it is advisable to discontinue injections.

a mechanical device for getting rid, by means of air suction, of dirt and dust from the floors and other parts of a house. It consists in the main of a nozzle which is run over the area that needs cleaning, a pipe connecting the nozzle with a separator where the dust and dirt are removed from the air, and an exhausting apparatus for producing a vacuum. The nozzles are in such shapes and sizes as the work may require. Some vacuum cleaners are operated by current which is derived from connection with a lamp socket. Another of a more extensive kind, mounted on a carriage and driven by an internal combustion engine, is stationed outside the building to be cleaned and the hose passed through the window. The third ssed throu type is located as a rule in the basement of a building and is connected by permanent pipes with outlets to which nozzles and hoses may be attached in different parts of the buildings.

the membranous canal leading from the from the uterus or womb to the exthem to recognize the practernal genitalia. The vagina in lower mammals, such as the Ornithorhynchus, opens into cloaca, while in the kangaroos and other Marsupialia it opens into a canal named the uro-genital canal, which receives the efferent ducts of the urinary organs. In higher quadrupeds the vagina is distinct both from the rectum and the urinary ducts. In the human subject it attains a length of about four measured along its anterior wall inches and six inches measured on its posterior surface. It lies between the bladder and rectum; constricted at its commencement it becomes dilated toward its uterine end. The coats of the vagina number three-an external or muscular layer, a layer of erectile tissue, and an inner or mucous layer. The mucous layer is thrown into folds or rugæ, which permit the distension of the canal in the process of parturition.
