In a number of excellent papers Walshe1 has called attention to the possibilities of the clinical application of the Magnus-de Kleijn tonic neck reflexes. Reference to the literature shows that early in their work Magnus2 and de Kleijn made observations on man. Since that time a few continental workers have made similar observations in isolated instances. Finally, Simons3 attempted to apply the physiologic facts to a great variety of cases. We have attempted to elicit these tonic neck and labyrinthine reflexes in cases of hemiplegia, tumor of the brain, and in many cases of tuberculous meningitis. We believe that the reflexes may have some localizing value and considerable diagnostic significance, particularly in tuberculous meningitis.
Early in 1909, Magnus and de Kleijn elicited certain reflexes in decerebrate animals. As is well known, the decerebrate animal of Sherrington shows extensor rigidity of all the extremities. Magnus found that rotation
