The lever is made of thin brass tubing rigidly attached at the fulcrum, Fig 4. This point is transversely pierced with a tube which firmly holds the axle which turns in bearings in the frame. The entire construction is such that, though light, the instrument is very rigid and compact. All parts are readily accessible. The horizontal arms of the lever are pierced with perpendicular holes at intervals of one centimeter from the fulcrum. These holes serve to mark centimeter intervals, and as points of attachment for the QU:. Fig. 2. Myograph. Posterio-lateral view. A. Frame. B. Lever. C. lyever rest or after-loading screw. D.

The method of mounting a muscle-nerve preparation is shown by the dotted lines. weight pan and other accessories. The openings in both ends are taper reamed to facilitate attachment of extensions. The forward arm to which the writing point is usually affixed is transversely pierced about two centimeters from the end by a pin which is permanently soldered in place, so that when a straw is forcibly thrust into the tube it is split, and thus expanded ; or if the end be cut obliquely, it is compressed firmly between the pin and the side of the tube, thus providing a simple means of instantly and rigidly affixing straws of various 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 Guthrie, Charles Claude, b. 1880.
