Finally the conical end M of a micrometer-screw (also rigidly attached to the bed plate) gives the remote end of the rod rr any desirable fiducial position. This micrometer M has the further advantage of permitting an independent corroborative standardization of the contact lever, as there would obviously always be sufficient elastic yielding in the apparatus to considerably shift the interference fringes; but it is better to free the rod from the coil at the rear end, also. In the experiments made, the breadth of the ray rectangle mm' of the inter- ferometer was 6 = cm.; the normal distance between the rod rr and the axis a, cm.; the length of the contact lever a to mm', cm.; and the length of the axle a, 10 cm. The rod rr may be easily withdrawn and others Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
