| the lamp. the carbon being perfectly
adjusted and its content being pure.
Under such conditions there is an in
tensive arc which IL reflected from mir
| rors and concentrated to establish the
great amount of light given by one Of
these projectors. However when the
carbon Is being fed toward the arc a
