DROSOM'ETER ( front Sp6cros, drosos, dew pirpov, in•a-tirr). An apparatus tor measuring the quantity of dew fornted in a unit of time per unit area of surface. The surface ay be either a horizontal metal plate or a leaf hanging naturally, er a hit of wool or cotton representing a large surface of foie tihres. The unit 01 time is usually one hour, and the measurement is made in the early morning, be fore the rising sun evaporates the dew. \N'hen t he apparatus is made self. registering. the surface, with its accumulating dew, hangs at one end of as delicate balance, or from a delicate spiral metallic spring, and by its gradual sinking moves the index that makes the record on as moving sheet of paper. Al though many forms have been suggested, yet Lone have been considered to give results that are comparable us ith each other from day to day, owing largely to the fact that the slightest change in the surface that receives the moisture alters the quantity of dew that is caught. Even the same bit 14 W1101, when used day after day, changes its nature in this respect. if a inetallie surface is used. its behavior 'mist be compared frequently with a standard. partly because dif ferent metals have different properties, but prin cipally because the same surface, when it he greasy. dirty, or scratched, has different
