    • n thermograph An automatic self-registering thermometer. A variety of forms have been used, involving different principles and methods. In the photographic method mercurial thermometers are used in the following manner: near the top of the mercury in the stem an air-bubble separates the column; by the action of a system of lenses the light from a lamp passes through the air-bubble, and throws the image of the bubble on the surface of a revolving cylinder upon which is wrapped a sheet of sensitized paper; no other light except the ray passing through the bubble enters the dark chamber containing the cylinder, and a photographic registration is therefore made of the oscillations of the mercury-column.
