This varies alittle, according as the head and neck are raised, and so the dorsalcurve increases. This was so frequently observed in the second50 cases, where the glucose-stovain compound was alone used, as to SPINAL ANALGESIA AND EPIDURAL INJECTIONS 417 be remarkable. Of course this may be modified somewhat by raisingthe pelvis a little, as has usually been done, to hasten the flow of the.
