Barnuni and McNoahs metallic barrel (Fig. 3395)is coated on both sides with lead, and the joints madeby Iiveting and soldering. There are many patents for compositions, modes,and machinery for thus impreg-nating, and for coating bar- Fig. foi this purpose. Oil-test. For ascertainingthe degree of heat at which.
