Uterine Dlnea»e§. Uterus is liable to disease depending upon a pathological change in any of the tissues which enter into its composition; e.g., there may be a catarrh of its lining mucous membrane; upon a malposition, either in whole or in part of the organ itself, as retroversion or retroflexion; or upon an abnormal manifestation of its function, as metrorrhagia. Because of the large distribution of nerve tissue to the organ and its surrounding parts, uterine diseases often assume a seriousness far beyond the extent of the local lesion.

Vaccination. A century ago smallpox was the great destroyer of the human race. It was known that one attack prevented a second and many people were inoculated with the disease when in a state of health, and the disease could be better controlled, to render them immune. Dr. Edward Jenner (1749-1823). an English physician, had his attention called to the belief anions; the country people of Gloucestershire that an attack of cowpox rendered the person immune to smallpox. This was while he was a medical student, prior to 1770. He made a careful study of the subject after he entered upon practice and became convinced of its truth. He made his first vaccination in 1796. The value of his discovery was recognized, and as its employment became treneral, the number of cases of smallpox became fewer and its relative mortality became less. At the present time, many physicians after years of extended practice have never seen a case of smallpox. Cowpox (vaccinia) is a disease of the bovida?, manifesting itself in an eruption on the udder. The virus, secured from the developed reside on a heifer, is inoculated by removing a small area of the epidermis of the arm. or other portion of the body, and applying the vaccine lymph to the denuded part. This, when it "takes," induces a well-marked eruption, and the individual is rendered immune to smallpox: or, if not entirely immune, the resulting attack is much lighter and seldom fatal. The protection from vaccination is lost after a time, and it is well to be vaccinated from time to time, especially should there be an outbreak of smallpox in the vicinity.

See Air-chamber. Vacuum-Pan. Apparatus for evaporating liquids at low temperatures, invented by Howard, an Englishman, 1813. In sugar refineries the pan is made of copper, with a hemispherical top and bottom, connected with a cylinder. The bottom is sometimes double, steam circulating in the space between the two bottoms. Within the pan are several series of copper steam pipes. Connected with the top of the pan is a condenser, an iron box, with series of cold water pipes, by which
the spray of sweet water from the pan is condensed. Connected with the latter is the condenser, a large iron box. where a shower of water condenses the steam, and, by its long tail pipe, assists in maintaining the vacuum in the pan. Beyond the condenser is the vacuum-pump which completes the vacuum. The sugar solution is evaporated by the heat of the steam in the steam-pipes and jacket at a temperature of 150° F.. with a vacuum of 27 in., thus avoiding- the risk of decomposing the sugar. These pans are used for condensing milk, glycerin, and other organic liquids.

Valence. That property of an element by virtue of which its atom has the power of holding a definite number of other atoms in combination. When hydrogen and chlorine unite, it is believed that one atom of each enter into combination: these elements are called univalent. If an element has the power to hold two hydrogen or two chlorine atoms in combination it is bivalent; e.g., oxygen and calcium. Nitrogen is trivalent in NH3, pentavalent in NH,C1. The highest valence is VIII.; e.g., OsO,. Valence is variable according to the conditions; thus nitrogen forms five different compounds with oxygen.
