CRAMER Cramer Automatic (Mechanical Type.) From what has already been said, the principles involvedin the construction of these instruments and the general de-tails of their construction are no doubt fairly well understood. There are two thermometers in the left hand or dry bulbcompartment, one acting as a thermostat to control the tem-perature and the other controlling the humidity by acting inconjunction with the wet bulb thermometer in the right handor wet bulb compartment; the wet bulb temperature is pro-duced by a spray device discharging into a glass cylinder, asshown; in the upper compartment is the actuating mechanism. The electrical type of instrument is the most sensitive, andin fact, compares favorably with the best scientific instrumentsproduced anywhere, and for any purpose; the mechanicaltype is just as positive and accurate, but of a lesser degree ofsensibility, being therefore specially designed for work wherethe most exacting conditions do not exist. Both of these instruments are simple in d
