First printing of an importent paper on temperature measuring, being Callendar's first work.""Callendar’s first publication, which was communicated to the Royal Society in 1886, dealt with platinum resistance thermometry. Sir Humphry Davy had discovered the dependence of the electrical resistance of metals on temperature (1821), and the German engineer Ernst Werner von Siemens had used this phenomenon in the construction of a platinum resistance thermometer (1861). Callendar made elaborate experiments on this subject at the Cavendish Laboratory in Cambridge, in which he compared the platinum resistance thermometer with Regnault’s normal air thermometer and from which he deduced that the resistance of a properly made platinum wire can be related to the reading of the air thermometer by a parabolic formula that was accurate within 1 percent.""(DSB).
