    index fingers of the operator by the upper limbs, and tbus fixing the sternal ends of the ribs, is brought into use for the elevation of the ribs with considerable impetus ; moreover, the diaphragm descends by virtue of the impulse which is communicated to the abdominal con- tents. By this means a deep inspiration is quite passively produced (2nd movement, inspiratory). After a pause of a few seconds in 1st inspiratory position, the child is again swung upwards into the previous position (1st movement, 2nd position, expiratory), and while it sinks slowly forwards it brings its whole weight to bear on the thumbs, which rest on the anterior thoracic wall, and mechanical expiration again ensues. At this point any inspired fluids always pour copiously from the mouth and nose, and generally meconium from the anus. The proceeding is repeated eight or ten times a minute, but more slowly when the inspired fluids flow from the mouth and nose. Description of apparatus. Tracheotomy was performed, and a cannula tied into the trachea, this cannula being in connection with an india-rubber tube, interrupted by a T-piece closed by a clamp, for the purpose of admitting air when desired. (When this clamp was opened the manometer is said to have been readjusted.) The other end of this tube was connected with a V-tnbe filled with water to a marked point, about half-way up. Inspii'ation, therefore, pro- duced a rise of the water in the limb of the tube to which the india-rubber tube was attached, and expiration a corresponding fall. The readings in inches refer to the height of the fluid in this limb above the zero or Ime of original level (the actual height of the column of fluid «
