In all, three pieces of apparatus were de-signed and tried out before obtaining a devicewhich vrould give accurate and satisfactory results. The base A Fig. I of the first instrumentwas designed to sit on the tops of the pans. Ahole, 3/4 in diameter was based in the middleof the base to take a vtooden upright 22 serai-circular wooden arc B was nailed to thisupright as shown. A cork float C 2 indiameter was fastened by means of a stiff wire toa movable member D 12 long. This member waspivoted to the upright to give a 5 to 1 Fie;
